Igneous rocks yield valuable paleoclimate and geochemical data through the analysis of their trapped volatile components and isotopic compositions.

The analysis

The claim that igneous rocks provide paleoclimate and environmental data via isotopic composition and trapped volatiles is directly supported by multiple retrieved studies. Specifically, paper [1] discusses using micro-FTIR to measure volatiles in minerals and glasses within igneous systems to understand paleoclimate, while papers [3] and [4] analyze isotopic compositions (such as mercury isotopes) in various igneous rocks to trace volatile inventories, crust-mantle interactions, and environmental changes. There are no refuting papers.
