Environmental Effects of Volcanic Volatile Fluxes From Subaerial Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 103-116., 2021

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.

Thermobarometry of Ca-amphibole in a Typical Low–temperature I-type Granite from Kashmar, Iran [PDF]

open access: yesFanāvarī-i āmūzish, 2007
The Kashmar granitoid (42.5 Ma) occurs in NE Central Iran Plate (CIP). It mainly includes felsic metaluminous (ASI ≤ 1) I–type granite and granodiorite plutons. Microprobe analyses show that the Kashmar amphiboles are low in Ti and (Na+K)A contents (all <

Carboniferous high-potassium I-type granitoid magmatism in the Eastern Pontides: The Gümüşhane pluton (NE Turkey)

open access: yesLithos, 2010
Abstract The Gumushane pluton, a high-K calc-alkaline I-type granodiorite/granite complex, forms an important component of the pre-Liassic basement of the Eastern Pontides (NE Turkey). In its eastern part, the pluton shows a compositional zonation ranging from biotite–hornblende granodiorite in the NW through biotite–hornblende granite to ...
