Mineralogy of the Fuller's Earth of Rajasthan, India

The paper incorporates the results of grain size and mineralogical investigations carried out on the clays of the Eocene Fuller's earth formation, collected from various localities in Rajasthan. The major clay mineral is palygorskite-attapulgite, The heavy mineral assemblage suggests a metamorphic provenance. The depositional environment of this Fuller's earth formation seems to be in alkaline, hypersaline coastal lagoons.
