On land, especially in the Euramerican part of Pangea, the equatorial regions are covered by forests. The moist tropical climate produces a lush plant growth, which eventually becomes the great Coal Deposits (hence the name Carboniferous - "coal bearing"). The fern-like but seed-bearing pterido...

The large amount of Neoproterozoic and Lower Paleozoic ages obtained in this study suggests that these periods played a significant role in the continental crustal growth history of Western Europe.doi:10.1016/j.gr.2009.05.007Jérémie Melleton
in the Upper Paleozoic of Sulige Gas Field.The test data of fluid inclusions and the burial history show that two periods from the late stage of Early Jurassic to the late stage of Late Jurassic(190~154Ma bp)and Early Cretaceous(137~96Ma bp)are the main gas accumulation period in the ...
GEOCARBSULFOR, and the original GEOCARBSULF, are driven primarily by the carbon isotope record, and as such, the model distinguishes a major change in the carbon cycle from the Ordovician to Carboniferous periods, which we attribute to the expansion of land plants and the rise of the first fo...
Hydrocarbon Accumulation Periods in the Upper Paleozoic Strata of the Western Ordos Basin, China, Based on Fluid Inclusions and Basin Modeling The upper Paleozoic strata in the western part of the Ordos Basin have rich oil and gas resources but low exploration levels. These strata were subjected ...
Trilobites, existing today only in fossil form, was a class of early arthropod. When life exploded into animal form marking the beginning of the Paleozoic, it was this prolific arthropod that became the signpost for the era. Eras are geologic time periods that have characteristics that sets it...

The distinguishing criteria include crystalline morphology, luminescence, grain size and forming stage (including the stage of deposition and different periods of the diagenesis progress). Geochemical proxies, such as an Al-Fe-Mn ternary diagram, negative correlations of Zr vs. SiO2, and positive ...
