Detrital zircon populations of the South Qiangtang terrane (SQT) provide vital information for reconstructing Tethyan evolution Tibetan Plateau but are obscured by undefined affiliation detrital samples and superimposition multiple tectonothermal events. We outlined SQT based on geological mapping collated Cambrian-Triassic to investigate representative populations. Although diachronous strata ...

Abstract The Ordovician–Silurian (~485–419 Ma) was a time of considerable evolutionary upheaval, encompassing both great diversification and one the first major mass extinctions. Ordovician coincided with global climatic cooling paleocontinental collision, ecological impacts which were mediated by region-specific processes including substrate changes, biotic invasions, tectonic movements. From ...

The Ordovician biodiversification is considered one of the most significant radiations in marine ecosystems entire Phanerozoic. Originally recognized as ‘Ordovician Radiation’, a label retained during 1980s and 1990s, term ‘Great Biodiversification Event’ (GOBE) was coined late 1990s subsequently adopted by scientific community. biodiversification, has always been long-term adaptive radiation, ...

The Great Ordovician Biodiversification Event” (GOBE) was arguably the most important and sustained increase of marine biodiversity in Earth’s history. During a short time span of 25 Ma, an “explosion” of diversity at the order, family, genus, and species level occurred. The combined effects of several geological and biological processes helped generate the GOBE. The peak of the GOBE correlates...
