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.

THE PRECAMBRIAN HISTORY OF THE ORIGIN AND EVOLUTION OF THE SOLAR SYSTEM AND EARTH. PART 1
The paper provides a review of early stages of development the Solar System and the geological history of Earth with reference to the latest data on the origin of the Solar System and the formation of the first continental rocks and results of studies of

Basement Nature of the West Junggar Terrane: Insight from the Age and Hf-O-H2O of Xenocrystic Zircons from Jurassic Basalt [PDF]
The West Junggar region is located in the southwestern part of the Central Asian Orogenic Belt (CAOB). The basement nature of the West Junggar terrane—whether ancient or juvenile—has long fueled debate.

Plagioclasites from chromite-bearing ultramafic rocks of the Rai-Iz massif
The corundum-bearing and without-corundum plagioclasites from chromite-bearing ultramafic rocks of Rai-Iz massif were studied. Chemical composition of the rock-forming minerals and rock geochemical characteristics was determined.
