Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement
Geophysical Monograph Series, Page 27-82., 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.

Magmatic fractionation of trace elements in biotite with emphasis on indium in the Salmi batholith, Russian Karelia [PDF]
, 2020 Biotite is one of the most common ferromagnesian phases in granitic systems and has a crystal lattice allowing for a range of cation substitutions. The mineral can record whole rock chemistry, mirror processes in the rocks and indicate local metal ...

Meccanismi di sostituzione del titano nella biotite in funzione dell'ambiente petrogenetico. [PDF]
, 2022 The purpose of this thesis is to investigate on the relationships between mechanisms of Ti substitution in biotite and petrogenetic environments. Ti can be accommodated in biotite according to three main substitution mechanisms: Ti-vacancy, where ...

Electron Microprobe Analysis of Biotite with Reequilibration Texture in Altered Trachyte
Yankuang ceshi, 2019 BACKGROUND The chemical composition of biotite contains important genetic information. The in-situ analyses of biotite with metasomatic texture can reflect the migration of the elements during the metasomatic alteration, and provide mineralogical ...
