May 1, 2021 · Gas results of the Silurian show some of the greatest variation in oxygen contents measured in halite during the early Paleozoic. The Mallowa salt (Carribuddy Group) of the Canning Basin (Australia) comes in with a low oxygen content of 12.9% (DM) and comparable 14.3% using the BCM method ( Table 1, Suppl. Fig. S4). Cenozoic volcanic and Paleozoic magmatic-metamorphic basement rocks have been proposed as the principal sources of lithium in the salars of the Altiplano-Puna plateau (Risacher and Fritz 2009; Hofstra et al. 2013; Meixner et al. 2020; López Steinmetz et al. 2020, among others).

This event is sometimes called the "Cambrian Explosion," because of the relatively short time over which this diversity of forms appears. It was once thought that Cambrian rocks ...

The Paleozoic Era ended with the approximately 47-million-year-long Permian Period, a major juncture in Earth history when the vast Pangean supercontinent continued its assembly (Fig. 1), and the global biota faced its greatest diversity crisis, the end-Permian mass extinction, the most extensive biotic decimation of the Phanerozoic.The Mesozoic Era followed with the approximately 50-million ...The Paleozoic ("old life") era is characterized by trilobites, the first four-limbed vertebrates, and the origin of land plants.

The Late Paleozoic Ice Age (LPIA; ca. 335–260 million years ago) was one of the most significant glacial events in Earth’s history. It records cycles of ice advance and retreat in southern high-latitude Gondwana and provides a deep-time perspective for climate–glaciation coevolution. However, climate records using clay mineral proxies from …Aug 25, 2023 · Carboniferous Period, fifth interval of the Paleozoic Era, succeeding the Devonian Period and preceding the Permian Period.
