ROW: Experimental and Theoretical Investigations of GraniticPhase Equilibria

低钙、高温的花岗岩岩浆在地壳延伸的地方很常见。 通常的方法无法完全表征这种高温岩浆的结晶。 这里建议对这种岩浆进行理论和实验研究。 作为 Fe 对长石系统钠离子区域相关系影响的主要实验和热力学研究的第一阶段，将确定含有铁橄榄石矿物的系统中的相关系。 这些结果将用于评估铁橄榄石在熔体中的热力学混合行为以及许多花岗岩岩浆中的稳定性关系。

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.
