Geochemical Investigations of Fuller’s Earth Deposits around Thano Bula Khan Area, Sindh, Pakistan

Abstract

Fuller’s Earth is essentially composed of clay minerals. The fuller’s earth deposits are present in the Tiyon formation (Ypresian-Lutetian) at both the flanks (Eastern and Western) of Surjan Anticline around the valley of Thano Bula Khan, Sindh. Geochemical study of the fuller’s earth deposits is conducted using X-ray Fluorescence (XRF) and Energy Dispersive Spectrometry (EDS). The study revealed the chemical composition of the fuller’s earth bed; that served as basic information (data) to interpret the depositional environment and depositional settings under which the fuller’s earth was formed. The present investigations also provide the clues to discourse the provenance of the deposits.
