TLDR
In this paper, the mineralogical characterizations of some Indian vermiculites and chlorites are reported, and significant differences in X-ray and thermal properties are observed, presumably due to presence of mixed layer minerals and/or other contaminations.Abstract:

Iron Oxide Removal from Soils and Clays by a Dithionite-Citrate System Buffered with Sodium Bicarbonate
TL;DR: In this article, the bicarbonate-buffered Na2S2O4-citrate system was used for removing free iron oxides from latosolic soils, and the least destructive of iron silicate clays.

The Geology of Vermiculite Occurrences
TL;DR: In this paper, it was shown that most and possibly all macroscopic-type vermiculite deposits formed by the action of supergene solutions on biotite and phlogopite are of super-gene origin.
