Abstract:

The present study aims at understanding the physico-chemical condition in which different coloured fluorites have been precipitated at Ambadongar. Although many techniques are available for genetic studies of rocks and minerals, in studying crystallization temperatures, the author has applied fluid inclusion techniques to conclude homogenization temperatures of Ambadongar fluorites. This study would also give an idea about the composition of the original magma from which fluid is generated and trapped in crystals during mineralization. Ambadongar fluorite occurs as vein and vug fillings localized along fractures within carbonatite and sandstones. Fluid inclusion studies of blue-green fluorite show that they crystallized at the highest temperature of all fluorites, with a temperature range of 168.2 to 192.1oC. Purple fluorite has been crystallized at a lower temperature than blue-green fluorite and possibly below 170oC. Yellow and colorless fluorites are late crystallized fluorites at low temperatures between 130.8oC and 119.3oC.
