The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

PERMIAN FUSULINID ASSEMBLAGES AND STRATIGRAPHY OF THE TRANSCAUCASIA
The Permian sequence of the Transcaucasia, which comprises the Davaly, Asni, Gnishik, Arpa, Khachik, and Akhura Formations, is described. A precise dating of the formations based on the analysis of fusulinid assemblages is also provided.

Upper Permian bryozoans of central East Greenland [PDF]
The bryozoan fauna in the Upper Permian Wegener Halvø, Ravnefjeld and Schuchert Dal formations, central East Greenland is of modest diversity, with only 15 genera identified. Bryozoans are most abundant in the Wegener Halvø Formation where they are important in the formation of carbonate buildups.

The Middle and Upper Permian Deposits in Gorski Kotar: Facts and Misconceptions
The frequent occurrence of sandstones and other coarse-grainedsedimentary rocks in Gorski Kotar indicates molasse type sedimentationas a consequence of the intensive erosion of all uplifted terrain ina tectonically active area.
