Petroleum titanium ore is a fine and medium-grained sandstone, mainly of quartz composition, with fine impregnations of the quartz-leucoxene aggregate and impregnation with heavy oil. Basically, the ore is represented by two types: the main ore is thin-grained ore and the less widespread sulphide type of ore, represented by breccias and blocks of sulphide cement and impregnations of minerals (anatase, rutile, quartz). The scale of the distribution of this type of mineralization is insignificant and is predicted to range from 3 to 10%.
Ore separations are characterized by interspersed texture, where in the sulphide (pyrite) cement dispersions of quartz, ilmenite, rutile are formed scattered individualized precipitates. In some areas of titanium minerals microcracks of monazite are observed. It is characteristic that in the impregnations of titanium minerals there is no germination of quartz. It is not a quartz-leukoxene aggregate - the main ore mineral of petroleum titanium ores, but a completely new type of titanium mineralization represented by grains of rather large sizes (0.1-0.3 mm).
