我国东南沿海粤、闽、浙、苏、皖诸省广泛分布新生代玄武岩。本文目的在于,研究包裹于碱性玄武质岩石中的两类超镁铁岩深源包体的矿物岩石学和地球化学,进而讨论包体的起源和成因。这二类深源包体是:一,橄榄岩类包体,又称绿色包体,以尖晶石二辉橄榄岩为主,分布遍及全区,主要产地见表1脚注;兼有石榴石二辉橄榄岩,见于浙江巨县和福建明溪。二,辉石岩类包体,又称黑色包体,以二辉岩和单斜辉石岩为主,伴生辉长岩和角闪石岩,主要见于广东普宁麒麟。
The southeastern coast of Guangdong in Guangdong, Fujian, Zhejiang, Jiangsu and Anhui provinces widely distributed Cenozoic basalts. The purpose of this paper is to study the mineralogy and geochemistry of two types of ultramafic inclusions in alkaline basaltic rocks, and to discuss the origin and genesis of the inclusions. These two types of deep-source inclusions are: I. Peridotite-type inclusions, also known as green inclusions, dominated by spinel lherzolites, distributed throughout the region, the main origin shown in Table 1 footnote; both garnet lherzolite , Found in Zhejiang Ju County and Fujian Mingxi. Second, pyroxene clades inclusions, also known as black inclusions, to two pyroxene and clinopyroxenite-based, associated gabbros and amphiboles, mainly found in Puning, Guangdong Unicorn.
