Description: The plate tectonic concept has nearly revolutionized the geo-sciences in the last decades. Many geodynamical, geophysical and geological phenomena could be understood for the first time. The investigation of the present-day global crustal kinematics is a crucial contribution which can be delivered by space geodesy only. Since the beginning of the MERIT-Campaign continuous good quality laser ranging data to LAGEOS are available. Using these data a precise estimation of present-day global-scale tectonic motion is possible. During the WEGENER/MEDLAS project the worldwide tracking network has been densified by a number of fixed and mobile stations in the southern Europe and eastern Mediterranean. Having now for a number of sites three to four occupations within four years significant site motions can be extracted. The derived motions are essential input information for deformation analyses and the interpretation of plate tectonic parameters.

Description: During the 3D seismic reflection survey within the project Integrated Seisrnics Oberpfalz 1989 (ISO89) the vibroseis source signals were recorded simultaneously with five threecomponent geophone borehole chain SEKANS or a single threecomponent borehole geophone, respectively, in the KTB pilot hole. The aim was to measure the traveltimes of direct waves in the depth range between 3220 and 3420 m in order to deduce spatial velocity inhomogeneities between surface and recording depth from traveltime residuals in the surroundings of the KTB. These data shall be used for improved static corrections if distinct from statics obtained by short refraction lines and first arrival analysis of surface data. A short description of the method is given which is based on approximation by least square fitted planes. Data examples and preliminary results are presented.

Description: The tool chain SEKAN 5 developed and constructed by PRAKLASEISMOS was proved to be capable of withstanding long-term operation under the given pressure and temperature conditions in a chemically active Dehydrill HT mud in the KTB Oberpfalz VB lA (350 bar, 110 °C, pH 10-11). The tool comprises five identical seismic receiver sondes which are equipped with a three-component receiver system, an electrically driven clamping unit and a magnetic compass system. The results of the reference tests and the measured compass values were subjected to critical checks. For the observation period the reference tests on different days for each individual sonde indicated good agreement with respect to specific signal forms. The differences in orientation determined from the seismic data and the compass values are between -11 degrees and -26 degrees. The cause of the differences can be explained in that the wave paths lie outside of the observation plane.

Description: The high reflectivity of the upper and middle crust of the Oberpfalz, both for near vertical and wide-angle reflections, was one reason for selecting this area as site for the German Continental Deep Drilling Program KTB. A peculiarity in the middle crust beneath the KTB site is the so-called Erbendorf-Body (EB) giving rise to extremely strong wide-angle reflections. It deserves special interest because its position right on the border between the Saxothuringian and Moldanubian zones of the Vari scan fold belt, the unusual high p-wave velocities (over 7.0 km/s) in its lower part at 11 to 14 km depth, and associated dipping reflectors suggest a possible lower crustal origin of the EB. A specially designed and so far unique wide-angle 3D-survey was carried out as part of the program "Integrated Seismics Oberpfalz 89" for investigating the spatial extent, the velocity distribution and the internal structure of the EB. The first results show clearly that the EB ist not a local phenomenon beneath the DEKORP4 line, but that it exists, yet with remarkable complexities, beneath the whole covered area between the Franconian Line and the Falkenberg granite complex. The wide-angle shots were also recorded by four 3-component geophones in the KTB pilot hole at 3195 to 3295 m depth and provided convincing evidence for s-wave splitting in the upper crust SE of the KTB location. This anisotropy effect seems to be related to the overall strike and dip of rock foliation in the zone of Erbendorf-VohenstrauB (ZEV).

Description: Data are presented from integrated special experiments which have been performed in conjunction with a seismic 30 reflection survey within the framework of IS089 ( Integrated Sei smi cs Oberpfal z 1989) coordinated by DEKOR(PG erman Continental Seismic Reflection Program) between July and Novembero f 1989. The main objective was to study the nature of P- and S-wave reflections and velocities, the Poisson's ratio and the seismic anisotropy in a medium of crystalline rocks around the KTB site (Continental Deep Drilling Program), where the borehole has reached a depth of 4000 m. A digital 5-unit geophone chain with 25 m spacing and three components was used for downhole recording. The program described here consists of: 1) shearwave 2D reflection profiling (SCMPw} ith two 10-12 km long lines crossing the KTB-site, source: 2 horizontal vibrators with different orientations, 3-component recording; 2) shearwave moving source profiling (S-MSP); downhole recording of the source points of the SCMP; 3) vertical seismic profiling (VSP) down to 3660 m with different source azimuths and offsets (zero-offset, 4 km, 8 km); P- and S-wave sources: explosives, horizontal and vertical vibrators, and horizontal hammer techniques. 4) multiple azimuth shearwave experiment (MASE) with 4 km and 8 km offset and horizontal vibrator sources (radial and transversal orientation). The VSP surveys display steeply dipping reflections, increasing in number below 3000 m depth. Horizontal structures, preferentially seen in the surface profiling, are the exception. Polarization analysis of shearwaves shows dominant azimuths in shearwave splitting which correlate with maximum horizontal stress (N 158° E) and with azimuth and dip of foliation.

Description: The moving source profiling (MSP) measurements are done by moving seismic sources along a surface line crossing the well site while a chain of geophones, placed within the well bore at a certain depth, records the seismic response. A multifold coverage of the subsurface can be obtained by repeating the source profile for a number of different geophone depths. This idea of altering the conventional vertical seismic profiling (VSP) geometry to allow illumination of subsurface structure away from the well is an attractive idea because it is designed to better locate horizons below the drill bit. If these target horizons can be correlated with reflectors in usual seismic profiles, recorded on the surface, the latter can be calibrated by the MSP results. Two MSP experiments were realized in the KTB pilot borehole. The first (MSP 1) included two N-S and E-W orientated source profiles of 10 km length and a single threecomponent geophone at 3585 m depth. Later a full MSP experiment (MSP 2) was run for one NE-SW orientated source profile and 20 different geophone depths. The source line was extended 7 km to the Northeast and 3 km to the Southwest of the well. A vibrator source produced seismic signals every 50 m. These shots were recorded by three-component geophones at depths from 3210 m to 3685 m with 25 m intervals resulting in a 20-fold coverage of the illuminated subsurface. Due to the difficulties encountered in crystalline environments, different processing techniques were combined for interpretation of the MSP data set. Aside from comparing measured first-break times with theoretical ones to determine seismic velocities of the overburden an MSP-CDP transformation for migration were applied. The steeply dipping boundary of the Falkenberg granitic intrusion was mapped as a distinct velocity contrast east of the KTB well. On the other hand, some remarkable seismic reflectors at depths between 4000 m and 10000 m are predicted to be hit by the future KTB main borehole.

Description: A depth migration is very sensitive to tl1e velocity model especially in the case of steeply dipping reflectors like the so-called SE reflectors at the KTB site. Velocity models derived from first breaks in vertical seismic profiling (YSP) experiments were used and compared with velocity data at the top of the crystalline refractor derived by short range measurements. Because of high picking errors, the possibility to compare seismic events with information of the upper part of the KTB HB hole allows only a very limited calibration of the velocity model. Based on the cutting profile, we assume that the reflectors SE-2 and SE--3 represent faults at 3600-3660 m depth and 5440-5560 m depth ( or a lithological contrast at 5540-5610 m depth). We suppose that the velocity of an average model starts at about 5.2 km/s at the surface, reaches a value of 6.0 km/s in about 2.5 km depth and remains approximately constant below. In that case, the reflector SE-1 will be hit at a depth of 7 .0 km. Because of the steep dip of reflector SE-1 which increases the size of the error range (from inaccurate velocity models and picking errors). the tolerance of about ±0.4 km is very high.

Description: The 3-D expanding spread experiment, performed within ISO 89 at the KTB site, has been evaluated under two aspects. The first aspect was the estimation of velocity-depth functions. Due to the limited reflection strength, estimating NMO velocities as a function of twoway traveltime was possible in east-west direction only. Thus the calculation of interval velocities, requiring the correction of 3D effects, was not possible. The second aspect was the directional dependency of the P-wave velocity at the top of the crystalline by evaluating the direct waves. After eliminating the effects of the lithology, a least-mean-squares anisotropy-velocity ellipse was fitted to the data with WSW as the direction of the maximum velocity and a velocity contrast of about 6%.

Description: A preliminary interpretation of the major 3-D reflectors is given by correlation with the surface geology and the drilled sections of the KTB Vorbohrung and the Hauptbohrung. Possible explanations for the reflections are discussed: lithological boundaries, cataclastic fault zones (partly filled with fluids) and other structural properties (e.g. foliation). Flat reflectors near the surface (MFl - 4) can be correlated with Permocarboniferous and Mesozoic sediments of the South German Platform. Special attention is drawn to a group of steeply NE-dipping reflectors (SEl, SE2, SE3) which are, obviously, produced by en-echelon fault structures of the Franconian Lineament. In the boreholes, SE2 can be identified as a bundle of faults near 3600 m. The calculated depth of the most prominent reflector SEl in the Hauptbohrung is between 6600 and 7100 m. It represents, probably, a deepreaching reverse fault zone which produces an offset of the reflections of the midcrustal "Erbendorf body" (B1 - B2/G4 - Gl).

Description: The determination of 3D-static corrections usually is possible only with the exact knowledge of thickness and velocity of the superficial layers. In order to determine these parameters extensive additional measurements are necessary, e.g. refraction seismics. These measurements can be reduced considerably if there is already a borehole in the survey area; the shots generated for the seismic survey can be recorded with a borehole geophone chain. The direct traveltimes determined from these records are lying on a 2nd-order plane (ideally a hyperboloid). If these traveltimes are influenced by e.g. differences in the elevations of the source location or velocity inhomogeneities, the first arrival traveltimes scatter around such a hyperboloid. The static corrections can be determined from the difference between the measured traveltime and the ideal hyperboloid. Further measurements are not required, because a precise knowledge of the parameters of the weathered layer is not necessary. In the following a method is presented (developed by Albrecht (1991) and Teichert (1991)) to determine the theoretical hyperboloid. Another method, described at the end of this report, is the determination of average velocities from picked and corrected first arrival traveltimes.

Description: A kinematic evaluation of first breaks of the direct P-wave in several VSPs, carried out at the KTB pilot hole in 1988 and 1989, is presented. After picking and correction to vertical traveltime, average and interval velocities were computed. The average velocity increases with depth caused by the successive closing of microcracks under increasing confining pressure. Tl1is average velocity-depth curve is the most accurate velocity information at the KTB site and can be used in migration and time-depth conversion problems in 2D- and 3D reflection surveys.

Description: The recordings of the wide-angle shots by 3-component geophones in the KTB pilot hole exhibit the effect of shear-wave splitting, that is the most diagnostic evidence of seismic anisotropy (Crampin, 1989). The possible reasons for seismic anisotropy will be discussed and the lateral extension of the anisotropic region will be estimated.

Description: Based on the DEKORP ISO 89 borehole experiments, the question of the existence of "seismic anisotropy at the KTB deep drilling site" has to be answered unambiguously with "yes". The anisotropy could be quantified in situ for a gneiss packet where it is apparently influenced by both rock foliation and cracks. The values obtained in the direct vicinity of the KTB pilot hole, however, cannot be extrapo l ated into its surroundings without modification: While the general trend of anisotropy with high velocity values towards SE-ESE is conserved, the amount of anisotropy shows smaller average values. This seems to reflect the inhomogeneous distribution of metamorphic rocks and granite in the target area. The direction of high seismic velocities (ESE) coincides approximately with the postulated direction of maximum horizontal tectonic stress in the Oberpfalz region.

Description: The detection of permeable fractures is one of the research objectives of the KTB-project. Among seismic methods the tube wave survey is suggested for this purpose. Open permeable fractures intersecting the borehole may generate secondary tube waves which show up as V-shaped traveltime patterns (Chevron pattern) in sonograms. We investigated tube waves transmitted and recorded by the VAL-(Variable Acoustic Logging)-tool technique. The depths of tube wave generation were determined. 85 percent of them correlate with planar structures seen in acoustic borehole televiewer (BHTV) logs. BHTV data reveal many structures. One third of these coincide with tube wave events in the VAL data. To verify the hypothesis that the occurence of a structure in both, traveltime and amplitude displays of BHTV data indicates an open fracture, we compared this dataset with stronger tube wave events assuming that the latter can be correlated to open fractures. We found no evidence for the correctness of the hypothesis. We compared tube wave events with caliper logs, temperature and mud conductivity anomalies during hydraulic tests, temperature anomalies during heat exchange test, core sample observations and gas-geochemical anomalies The comparison between these various borehole data is not as satisfactory as to ensure the reliability of tube wave analysis to determine open fractures. Earlier investigations suggest that amplitudes of tube wave events are related to hydraulic permeabilities. Deficiencies of the present tube wave dataset (VAL) and missing fluid logging for calibration purposes prevents us from quantitative analysis.
