摘要
台马岩体的地质学岩石学特征和锶、氧同位素特征一致表明,岩体的形成时代为海西晚期—印支早期;紫苏辉石花岗斑岩岩浆属壳源重熔岩浆,并在上侵定位过程中发生过深部同化混染作用。
Geology, petrology and the strontium and oxygen isotopes of Taimaintrusion simultaneously show that the intrusion formed in Late Hercyni-an Early Indosinian period. The magma of the hypersthene granite-porphyrybelongs to the crustal remelting type. In the process of emplacing, themagma experienced deep assimilation and contamination.
