近年来,实验岩石学的研究对象已从研究近地表的岩石和矿物转向研究地壳以至上地幔的岩石和矿物,并相应发展了高压实验技术。电子探针和穆斯保尔摄谱议已成为这一领域中必不可少的测试仪器。最初人们运用对于具有或者不具有钙长石及各种镁铁矿物的钠长石——正长石——石英——H_2O系的各种研究,来探讨花岗岩的成因。现在通常认为花岗岩主要是从液相形成,这种液相或者是原生岩浆,或者是由先成岩石再熔融而产生的次生液体。玄武岩浆系由上地幔中的二辉橄榄岩局部熔融所产生。在大气压或高压下研究镁橄榄石一透辉石一二氧化硅系,对玄武岩浆的这一形成机制进行了探讨。这就研究证明,
In recent years, the research object of experimental petrology has turned from the study of near-surface rocks and minerals to the study of rocks and minerals in the crust and the upper mantle, and correspondingly developed high-pressure experimental techniques. Electron probe and the Musk Paal spectroscopy has become an indispensable test instrument in this field. Originally, people used various studies on albite-orthoclase-quartz-H 2 O with or without anorthite and various types of mafic iron to investigate the genesis of the granite. It is now generally accepted that granites are formed predominantly from the liquid phase, either the native magma or the secondary fluid resulting from the remelting of the preformed rocks. Basalt magma is produced by partial melting of the lherzolite in the upper mantle. The formation mechanism of basaltic magma was investigated by studying forsterite-diopside-silica at atmospheric pressure or high pressure. This research shows that,
