Fluorite is important in most of the Malyy Khingan deposits particularly in the Khingan and Verkhniy Karadub ones. These deposits differ very substantially in mineralization scale but have numerous features in common. The fluorite in Verkhniy Karadub consists solely of the green variety and occurs as veinlets or less often as idiomorphic crystals. The position of the fluorite at Khingan is more complicated. It represented by two generations and various colors. This paper studied the fluorite composition pattern over time using ontogenetic analysis which is based on differential examination of the growth-zone sequence in particular crystal. The most important result is the identification of a clear-cut compositional pattern in the fluorite over time, in which the contents of the most of the trace components show a persistent tendency to decrease as the growth proceeds, and if the crystal has a uniform color, the composition varies over time in a single direction.
