    Notes: Major and trace element analyses have been obtained by wavelength dispersive X-ray fluorescence for the Geological Survey of Japan Igneous rock series and selected samples from the Sedimentary rock series reference samples. Additional trace element data for the Igneous rock series were obtained by instrumental neutron activation analysis. Samples were analyzed multiple times for 10 major elements (with loss-on-ignition) and the following trace elements; As, Ba, Ce, Co, Cr, Cs, Cu, Eu, Ga, Hf, La, Lu, Nb, Nd, Ni, Pb, Rb, Sb, Sc, Sm, Sr, Ta, Tb, Th, U, V, W, Y, Yb, Zn and Zr.

    Notes: Abstract Tholeiitic lava flows (Kirkpatrick Basalts) and dolerite sills and dikes (Ferrar Dolerites) of the Jurassic Ferrar Group from Antarctica and dolerite sills from Tasmania, Australia are characterised by initial strontium isotope ratios ranging from 0.7089 to 0.7153. The mean and standard deviation of 85 analyses is 0.7115±0.0012. Some of the scatter in the initial 87Sr/86Sr ratios can be attributed to sample inhomogeneity, analytical uncertainties and sample alteration. The published major element data show well-defined trends that are consistent with an evolution by fractional crystallization. Recognition of a parental magma is difficult due to the fractionated nature of the rocks. Trace element analyses, particularly the rare earth elements (REE) support a differentiation model. Compared to mid-ocean ridge basalts, Ferrar Group rocks are enriched in light REE. Kirkpatrick Basalts from the central Transantarctic Mountains show significant correlations between initial 87Sr/86Sr ratios and major elements only for SiO2 and CaO. The general lack of strong correlation is the basis for rejecting the possibility of wholesale contamination by sialic material as a possible cause of the high 87Sr/86Sr ratios. Selective contamination of the basaltic magmas is a possibility and cannot be completely discounted. It would probably involve a fluid phase in order to transport and mix the light REE, Rb, 87Sr, and other elements. By analogy with selective contamination of ocean ridge basalts by sea water it is difficult to envisage a similar process acting on magma emplaced in a non-marine environment. Because of the elevated values of the initial 87Sr/86Sr ratios, their similar average value over 2,500 km and the large volume of magma involved (4× 105 km3) a mantle origin for the high Sr ratios is preferred. Models to account for the enrichment of Rb and light REE in the Antarctic mantle during or prior to the Jurassic include: 1. addition of continental material from a Palezoic Mesozoic subduction zone; 2. metasomatism of volatile elements from the lower mantle; and 3. evolution of a mantle with a high Rb/Sr ratio.

    Notes: [Auszug] Mt Erebus is the only active and the largest of three volcanoes which form the bulk of Ross Island, in the Ross Sea (77.55 S, 167.17 E). It is made up chiefly of anorthoclase phonolite lavas and has sustained an active lava lake, at least since 1972, and possibly for more than a century. Most of ...

    Notes: Abstract Airborne correlation spectrometry (COSPEC) was used to measure the rate of SO2 emission at White Island on three dates, i.e., November 1983, 1230 ± 300 t/d; November 1984, 320 ± 120 t/d; and January 1985, 350 ± 150 t/d (t = metric tons). The lower emission rates are likely to reflect the long-term emission rates, whereas the November 1983 rate probably reflects conditions prior to the eruption of December 1983. The particle flux in the White Island plume, as determined with a quartz crystal microbalance/cascade in November 1983, was 1.3 t/d, unusually low for volcanic plumes. The observed plume particles, as shown from scanning electron microscopy, include halite, native sulfur, and silicates and are broadly similar to other volcanic plumes. Gas analyses from high-temperature volcanic fumaroles collected from June 1982 through November 1984 werde used together with the COSPEC data to estimate the flux of other gas species from White Island. The rates estimated are indicative of the long-term volcanic emission, i.e., 8000–9000 t/d H2O, 900–1000 t/d CO2, 70–80 t/d HCl, 1.5–2 t/d HF, and about 0.2 t/d NH3. The long-term thermal power output at White Island is estimated at about 400 MW.

    Notes: Abstract Water, F, and Cl contents of melt inclusions in phenocrysts from the 2-ka-old Taupo and Hatepe plinian tephras, and the ∼22-ka-old Okaia tephra from the Taupo volcanic center, New Zealand, were measured by electron and ion microprobe. Major and trace element chemistry of the inclusions is similar to that of bulk rock, supporting our assumption that volatile contents of inclusions are representative of the magma in which the crystals grew. Inclusions in the 2-ka Taupo plinian tephra contain a mean of 4.3 wt% H2O, 450 ppm F, and 1700 ppm Cl; from the Hatepe plinian tephra 4.3 wt% H2O, 430 ppm F, and 1700 ppm Cl; and from the Okaia tephra 5.9 wt% H2O, 470 ppm F, and 2100 ppm Cl. Sulfur was below the detection limit of 200 ppm. The constant H2O, F and Cl from a number of stratigraphic horizons in the tephra deposits suggest that the Taupo and Hatepe plinian tephras (〉8.2 km3 magma volume) were derived from a magma body that did not contain a strong volatile gradient. By inference, there is no pre-eruptive volatile difference between these plinian eruptions and a phrea-toplinian eruption which occurred between the two. Virtually no major element zonation is seen in this eruptive sequence. Although the Okaia tephra was also erupted from the Taupo volcanic center, probably from a similar vent area, its higher volatile contents and distinct composition as compared to the Taupo tephras show that it was derived from a different, and possibly deeper, magma body.

    Notes: Abstract Use of an airborne quartz crystal microbalance cascade impactor instrument together with a correlation spectrometer has allowed the flux of particles and their size distribution to be determined at Mount Erebus. The plume contributes 21±3 metric tomnes/day of aerosol particles to the Antarctic upper troposphere. The aerosol particles consist of larger (5–25 μm) particles of elemental sulfur and silica, a middle sized group of iron oxides and smaller particles (less than 1 μm) of complex liquids. Unlike many volcanic plumes, the Erebus plume has only a small amount of sulfate particles. The concentrations of particles in the Erebus plumes was 70–370 μm/m3. Limited sampling of the Antarctic atmosphere at 8 km altitude but hundreds of km away from Erebus obtained a few large particles of sulfur and silicates, suggesting a similarity with the Erebus plume. The fallout of these particles occurs slowly over a broad area of the Antarctic continent.

    In:  Supplement to: Krissek, Lawrence A; Kyle, Philip R (1998): Geochemical indicators of weathering and Cenozoic palaeoclimates in sediments from CRP-1 and CIROS-1, McMurdo Sound, Antarctica. Terra Antartica, 5(3), 673-680, hdl:10013/epic.28325.d001
    Publication Date: 2023-06-27
    Description: The CRP-1 core penetrated 148 m of Quaternary and lower Miocene glacigenic sediments. This material complements the Eocene trhough Miocene strata that was cored previously at CIROS-1, 70 km to the south. The paleoclimatic records of CRP-1 and CIROS-1 have been examined by calculating the Chemical Index of Alteration (CIA) of Nesbitt & Young (1982), using new data for CRP-1 materials and the data of Rose & Pyne (1988) for CIROS-1 mudstones. The CIA is calculated from the relative abundance of Al, K, Ca, and Na, and its magnitude increases as the effects of chemical weathering increase. However, changes in sediment provenance can also effect the CIA, and such changes appear to dominate some parts of the CRP-1 and CIROS-1 record. Relatively large (47-60) and variable CIA values in the lithologically defined „lower sequence“ at CIROS-1 record the influence of chemical weathering during the late Eocene, a result of relatively mild climates and glacial influence, but not glacial dominance. CIA values do decrease upsection through the Eocene, however, suggesting gradual climatic deterioration. The Oligocene and Miocene „upper sequence“ at CIROS-1 is characterized by lower (45-50) and more uniform CIA values. This part of the record clearly is affected by an increased contribution of mafic material derived from the McMurdo Volcanic Group, but also may indicate a change in paleoweathering intensity. CIA values for CRP-1 are uniformly low (〈45) and decrease slightly upsection, suggesting glacial dominance, although an increased influx of McMurdo Volcanic Group material is also indicated.
