The Significance of Magnetic Fabrics Preserved in Hydrothermally Altered Rocks

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Anisotropy of Magnetic Susceptibility (AMS) and Anisotropy of Magnetic Remanence (AMR) are critical petrofabric tools for investigating the evolution of volcano‐magmatic, tectonic, and surface process systems. These highly sensitive techniques can distinguish multiple magnetic fabrics within individual samples, crucial in assessing archives of

Two-Stage, Extreme Albitization of A-type Granites from Rajasthan, NW India [PDF]

, 2017
Albitization is a common process during which hydrothermal fluids convert plagioclase and/or K-feldspar into nearly pure albite; however, its specific mechanism in granitoids is not well understood. The c.

Turbidity in alkali feldspars from granitic pegmatites

, 1994
Alkali feldspars from pegmatite of Brazil and Spain have microscopic to submicroscopic inclusions giving a >turbid> and >clouded> appearance. Inclusions are isotropic, irregular and spatially associated with patch/vein lamellae in network and/Or isolated masses. Inclusions have no detectable lines in XRD and microprobe analyses show strong variability:
