REAL STRUCTURE AND PHYSICAL PROPERTIES OF CHROMITES AS AN INDICATOR OF THEIR GENESIS

Abstract

Spinels (Mg,Fe2+)(Cr,Al,Fe3+)2O4 are the most informative minerals for reconstruction of PT crystallization parameters and differentiation conditions of ultramafic melts [1]. It is known that the real structure and physical properties of spinels are governed by their formation conditions (chemical composition of the melt, temperature and pressure of crystallization, and others) [2, 3].
