TIMS Techniques for Measuring Strontium Isotope Ratios in Apatite Grains and Application to Igneous Rock Petrology. [PDF]
Rapid Commun Mass SpectromABSTRACT Rationale This study evaluates the potential of Sr isotopic compositions in apatite grains from magmatic rocks as a proxy for initial 87Sr/86Sr ratios, addressing the need for alternative approaches to conventional whole‐rock analyses in isotopic studies of granitoid systems.

Environmental Effects of Volcanic Volatile Fluxes From Subaerial Large Igneous Provinces
Geophysical 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]
Fanāvarī-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 <
