... that Glossopteris , which is abundant in the Permo-Carboniferous Coal Measures re-appears in the Desert Sandstone. As yet its presence has not been delected in the Taeniopteris- bearing … beds, nor in the Lower Cretaceous Rolling Downs Formation,” (which lay stratigraphically between the coal measures...

..., fusion of mineral grains, hardening, and similar morphological and chemical changes to those observed in earthenware ceramic and clay brick-making processes. Heat for pyrometamorphic transformations need not come from contact magmatic heat, but also from other sources, such as combustion of coal beds...

... ), the frequently observed low-Ca pyroxene shell at chondrule edges and the correlative core to edge silica activity gradient have also been considered as resulting from gas–melt interaction processes. Tissandier et al. (2002) demonstrated experimentally that partially molten olivine bearing chondrule-like...

... in the latter cases due to the presence of marker bedding planes. For the Lonar crater, the only markers that can be trusted for structural measurements are the subhorizontal flow layers in the undeformed target basalt. These layers are, however, less identifiable when the thickness of the layer is rather high...

...” and “Stefan” at the very edge of the Coulomb-Sarton Basin. 1 Wegener attained the distinction of a crater bearing his name because the rediscovery and general recognition of his work on continental drift happened to coincide with the initial photographic mapping of that side of the Moon. Wegener had...
