Abstract

A fluorite-calcite mineral association is to be reported and studied to the first time at Wadi Um Esh El Zarqa in the central Eastern Desert. This is a fissure filling vein deposit occurring in a. country of dioritic and amphibolitic rocks. The vein is trending generally N—S and is 1.20 ms width and about 400 ms in length. The fluorite has a mean specific gravity of 3.16, while the calcite has an average gravity of 2.72. The fluorite is altered to calcite. It is shown that the investigated flourite is formed most probably during a main pneumatolytic process and not during a hydrothermal phase.
