Migmatite-Like Textures In Anthracite: Further Evidence For Low-Grade Metamorphic Melting And Resolidification In High-Rank Coals, James C. Hower, Susan M. Rimmer, Maria Mastalerz, Nicola J. Wagner

Center for Applied Energy Research Faculty Publications

Previous studies demonstrated that melting, initiated by supercritical fluids in the 375–400 °C range, occurred as part of anthracite metamorphism in the Appalachian Basin. Based on the known behavior of vitrinite at high temperatures and, to a lesser extent, at high pressures, it was determined that the duration of the heating, melting, and resolidification event was about 1 h. In the current study, featureless vitrinite within banded maceral assemblages demonstrates the intimate association of melted and resolidified vitrinite with anthracite-rank macerals. By analogy with metamorphosed inorganic rocks, such associations represent diadysites and embrechites, i.e., cross-cutting and layered migmatites ...

When Dinosaurs Walked Through Diamonds: Constraining The Age Of Early Cretaceous Footprints In Volcanic Crater Sediments, Yasmin Jackson 2021 Southern Methodist University

When Dinosaurs Walked Through Diamonds: Constraining The Age Of Early Cretaceous Footprints In Volcanic Crater Sediments, Yasmin Jackson

SMU Journal of Undergraduate Research

The volcanic rocks of the Catoca Diamond Mine, northeastern Angola, were formed in an eruption ~118 million years ago. Above these rocks, researchers discovered Early Cretaceous mammalian, crocodilian, and sauropod dinosaur footprints in crater lake sediments. These footprints are among the relatively few vertebrate fossils from the Cretaceous Period (145-66 million years ago) found in Sub-Saharan Africa. The ~118 million-year-old age, which is the maximum age of the footprints, is provided by the uranium and lead isotope ratios in the zircon crystals from these volcanic rocks. The presence of dinosaur footprints limits the minimum age to 66 million years ago ...
