Mineralogy and paragenesis of the fluorite deposits from the Kerio Valley, Kenya

Abstract

Investigation of the mineralogy and paragenesis of the fluorite from the Kerio Valley shows that the mineralization resulted from residual magmatic solutions, which also led to the replacement of the crystalline limestone. Two types of inclusions–primary and secondary–are recognised. Four varieties of fluorite occur in the area. They are paragenetically related in the following order: white and yellow-brown varieties mineralized first, then the dark-grey variety and lastly the violet one.
