ROW: Experimental and Theoretical Investigations of GraniticPhase Equilibria

低钙、高温的花岗岩岩浆在地壳伸展的地方很常见。这种高温岩浆的结晶不能用通常的方法完全描述。本文建议对这类岩浆进行理论和实验研究。作为研究铁对长石体系钠区相关系影响的主要实验和热力学研究的第一阶段，将确定含有矿物铁长石的体系中的相关系。这些结果将用于评价熔体中铁矾石的热力学混合行为和许多花岗岩岩浆的稳定性关系。

Low-calcium, high temperature granitic magmas are common where the earth's crust has been extended. The crystallization of such high temperature magmas cannot be completely characterized by the usual approaches. It is proposed here to conduct a theoretical and experimental investigation of this kind of magma. As the first stage of a major experimental and thermodynamic investigation of the effect of Fe on the phase relations in the sodic regions of the feldspar system, phase relations in a system containing the mineral fayalite will be determined. These results will be used to evaluate of the thermoynamic mixing behavior of fayalite in melts and the stability relations in many granite magmas.
