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.

Tectonostratigraphic History of Mesopotamian Passive Margin during Mesozoic and Cenozoic, South Iraq. [PDF]
Passive margin of Mesopotamian zone formed by two tectonic phases: opening and closing phases. Opening tectonic phase (Permian-Jurassic) represents the beginning of Wilson cycle. This phase includes three stages: pre-rifting, rifting and post-rifting. In

Peneplains and tectonics in North-East Greenland after opening of the North-East Atlantic
Elevated plateaus with deeply incised valleys characterise elevated, passive continental margins (EPCMs) in all climate zones. These features are, however, a topic of debate regarding when and how the large-scale landscapes formed.

Geochemistry, petrogenesis, and tectonic setting of volcanic rocks in the SW of Torud (Shahrood) [PDF]
The study area is located in the south of Damghan, 160 km south of Shahrood, and 17 to 30 km south of Torud village. The area geologically, lies in the Cenozoic magmatic belt, a part of the Alpine-Himalayan belt, in the north of the structural zone of ...

The Holocene temperature conundrum answered by mollusk records from East Asia
Scientists have been puzzled by the disparity between climate simulations of the past 12,000 years and geological records. Dong et al. reconstructed past annual and seasonal temperatures from land snail records to examine the potential seasonal bias.

A review of amber and copal occurrences in Africa and their paleontological significance
The paleontological interest for fossil plant resins (amber and copal) has greatly increased in the last decades, as field studies have resulted in the discovery of various new deposits worldwide.
