    Notes: [Auszug] INITIATION and growth of explosion. Some recent experiments1 have shown that if azide crystals of different sizes are heated at a fixed temperature, crystals greater than a critical thickness will explode, whereas those below a critical thickness will decompose slowly. The critical thickness ...

    The domain structure of a transitional anorthite; a study by direct lattice-resolution electron microscopy (1973)
    Springer
    Contributions to mineralogy and petrology 41 (1973), S. 47-52 
    Details
    ISSN: 1432-0967
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences
    Notes: Abstract Direct resolution of lattice planes corresponding to a-, b- and c-reflections in a transitional anorthite has shown that the material consists of domains of body-centered anorthite (I-An) and primitive anorthite (P-An) in approximately equal proportions. The domains of P-An appear lenticular in shape. Their thickness and orientation readily account for the observed streaking of the c- and d-reflections. Adjacent domains of P-An (separated by a domain of I-An) are observed to be either in register or in antiphase relation, the fault vector being the body-centering vector.

    A transmission electron microscope study of naturally deformed orthopyroxene (1976)
    Springer
    Contributions to mineralogy and petrology 57 (1976), S. 163-177 
    Details
    ISSN: 1432-0967
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences
    Notes: Abstract A model is proposed for the production of clinopyroxene lamellae in orthopyroxene by a dislocation mechanism based on simple shear. Four possible shears are described. Two shears apply to each subcell of orthopyroxene, one with ψ=13.3° in one sense, the other with ψ=18.3° in the opposite sense.The senses of shears of the same magnitude in adjacent cells are also opposite. All shears produce the same structure, but in two discrete orientations which can be distinguished from electron diffraction patterns. However, the operative shear cannot be uniquely determined from the diffraction patterns alone. The characteristics of the diffraction contrast fringes and associated partial dislocations observed by transmission electron microscopy in a naturally deformed orthopyroxene are shown to be consistent with the proposed model.

    Dislocation structure of the deformation lamellae in synthetic quartz; a study by electron and optical microscopy (1970)
    Springer
    Contributions to mineralogy and petrology 29 (1970), S. 104-115 
    Details
    ISSN: 1432-0967
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences
    Notes: Abstract Single crystals of experimentally deformed synthetic quartz showing optical deformation lamellae were examined by transmission electron microscopy. Dislocations are distributed fairly uniformly throughout the crystal. However, parallel to the trace of the deformation lamellae, which may be irrational, there are walls of tangled dislocations whose characteristics suggest that they are directly associated with the lamellae. The nature and formation of the optical image is discussed in detail.

    Dislocations associated with optical features in naturally-deformed olivine (1971)
    Springer
    Contributions to mineralogy and petrology 30 (1971), S. 53-63 
    Details
    ISSN: 1432-0967
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences
    Notes: Abstract Transmission electron microscopy has been used for the direct observation of dislocations in naturally-deformed olivine. The dislocations are arranged in arrays forming low-angle sub-boundaries which have been identified with features observed in the optical microscope. Comparison of this dislocation substructure with that observed in olivine, and in metals, experimentally deformed under various conditions, suggests that the deformation in nature has occurred by creep. Possible mechanisms of creep, involving the cooperative glide and climb of dislocations, are discussed.

    Transmission electron microscope study of the domain structures associated with the b-, c-, d-, e- and f-reflections in plagioclase feldspars (1974)
    Springer
    Contributions to mineralogy and petrology 44 (1974), S. 237-249 
    Details
    ISSN: 1432-0967
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences
    Notes: Abstract Ten specimens of plagioclase feldspars (An100 to An25) have been examined by transmission electron microscopy using dark field and direct lattice imaging. The specimens are classified into two groups: (i) those that have been quenched from the melt (synthetic An100, An95, An66 and An50) and (ii) those that have been cooled relatively slowly (An94, An77, An75, An52, An32 and An26). The observed contrast is interpreted in detail using the two-beam dynamical theory of electron diffraction contrast. The fault vectors of the antiphase boundaries (APBs) observed in An100 and An77 are determined. Direct resolution of the sublattice and superlattice in specimens of intermediate composition (An75 to An25) indicates that the superlattice is not a regular array of out-of-step faults and is probably due to a simple sinusoidal distortion of the structure. Only three specimens (An100, An77 and An50) exhibited a single structural type. All the remaining specimens consisted of intergrowths of two structural types. The structural type present in any particular specimen depends upon its An-content and thermal history. The rate of transformation from any structural type to a lower-temperature structural type appears to decrease with decreasing An-content.

    Two-dimensional lattice images of stacking disorder in wollastonite (1976)
    Springer
    Contributions to mineralogy and petrology 55 (1976), S. 303-309 
    Details
    ISSN: 1432-0967
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences
    Notes: Abstract Two-dimensional lattice images of low-temperature triclinic wollastonite (α-CaSiO3) indicate that two types of stacking disorder occur: (1) simple stacking faults and (2) twinning which also involves displacement in the composition plane. Both types of defect produce very similar structures with monoclinic symmetry (parawollastonite). Dislocations are involved at the termination of lamellae of parawollastonite in a triclinic matrix and a model for the dislocation core is proposed.
