Figure 11 in A methane seep from the deep-marine, late Eocene Keasey Formation, Rock Creek, Columbia County, Oregon

Figure 11. Depiction of solemyid burrow (Fig. 11A, from Hickman 1984) and lucinid burrow (Fig. 11B, from Hickman 1994, 2003b). Such burrows span oxic-anoxic boundaries to provide their symbionts with sulfide from the sediment and oxygen from the water column and as well as meeting their own oxygen needs. The presence of an articulated fossil solemyid in life position (i.e. in situ) indicates the presence of an ancient oxic-anoxic interface, regardless of whether the burrow is clearly preserved. Extensive bioturbation characteristic of the massive Keasey siltstone and mudstone units is likely to obliterate uncemented burrow ichnofabrics of solemyids. See Droser & Bottjer (1989) for history of bioturbation. On the other hand, burrows of decapods are more likely to be preserved since decapod crustaceans secrete a calcareous cement that prevents burrows from caving — e.g. collophanite (an amorphous calcium phosphate). See Weimer and Hoyt (1964).

Growth-related formation mechanism of I3-type basal stacking fault in epitaxially grown hexagonal Ge-2H

The hexagonal-2H crystal phase of Ge recently emerged as a promising direct bandgap semiconductor in the mid-infrared range providing new prospects of additional opto-electronic functionalities of group-IV semiconductors (Ge and SiGe). The controlled synthesis of such hexagonal (2H) Ge phase is a challenge that can be overcome by using wurtzite GaAs nanowires as a template. However, depending on growth conditions, unusual basal stacking faults (BSFs) of I3-type are formed in the metastable 2H structure. The growth of such core/shell heterostructures is observed in situ and in real-time by means of environmental transmission electron microscopy using chemical vapour deposition. The observations provide direct evidence of a step-flow growth of Ge-2H epilayers and reveal the growth-related formation of I3-BSF during unstable growth. Their formation conditions are dynamically investigated. Through these in situ observations, we can propose a scenario for the nucleation of I3-type BSFs that is likely valid for any metastable hexagonal 2H or wurtzite structures grown on m-plane substrates. Conditions are identified to avoid their formation for perfect crystalline synthesis of SiGe-2H. This data set contains all the processed supporting videos of in-situ TEM observations .
