斜長角閃巖

Hornblende bearing varieties bridge the gap over to amphibolites which are in bands and dikes. 含角閃石的變種填補(bǔ)了帶狀和脈狀角閃巖的中間相。

The characteristics and distributing features of the amphibolites from Archaean era are discussed in this paper. 本文研究了金廠峪金礦太古代斜長角閃巖中構(gòu)造巖的特征和分布特點(diǎn);

While, the sodium amphibolites in the later stage compatible with the present foliation, might be related to the structure deformation. 晚期的鈉質(zhì)角閃石構(gòu)成了現(xiàn)存片理，可能與后期構(gòu)造變形有關(guān)。

These basic volcanic rocks underwent high pressure metamorphism for two times, at least, in which sodium amphibolites are formed by high pressure metamorphism with different genesis. 這些基性火山巖至少發(fā)生了兩期高壓變質(zhì)，兩期高壓變質(zhì)形成的鈉質(zhì)角閃石具有不同成因。
