ABSTRACT: This study is aimed to provide some new informations on the titanium content and titanium partitioning in rocks, and titanium deposits. Titanium is most abundant element in the earth`s crust .and has a strong affinity foroxygen... At the present» titanium metal and alloys are- used in the aerospace Industries as structural components stre.og.htto high, temperatures.,In the primary titanium deposits, titanium minerals such as rutile and ilmenite which have trade grade,, form as products of the crystallization of igneous magmas and as recrystallizauon products in metamorphic rocks. The behavior oftitanium In magmatic crystallization is depends on such factors as the initial titanium contents of the magma» thechemical activities-of iron, silicon, and. aluminum» the partial pressure of oxygen, and the temperature of crystallization.Rutile-bearing metamorphic rocks are generally related to hightemperature and pressure-facies rocks. Anorthositemassifs are economically important sources of titanium minerals.
