对鄂尔多斯盆地东胜地区和吐哈盆地十红滩地区砂岩型铀矿的岩石学特征、地质构造、含矿建造与古水文地质条件及铀矿的成矿特点等进行了综合分析与研究。

This paper reports the investigation on the petrology of spinel harzburgite and olivine pyroxenite in the Darbut ophiolitic mélange, as well as the worm-like intergrowth texture composed of Cr-spinel and orthopyroxene wide-spreading in harzburgite. Our study shows that the observed intergrowth texture is not a graphic texture or a symplectite as assumed by previous research, instead, it is a product of the evolution of the Cr-rich magma formed after the melting of the primitive mantle.

通过研究西准噶尔达拉布特蛇绿混杂岩中方辉橄榄岩和橄榄辉石岩的岩石学特征，分析方辉橄榄岩广泛发育的铬尖晶石和斜方辉石构成的蠕虫状共生连晶结构的成因，得出结论认为：这种共生连晶结构不是前人所认为的文象结构或者石榴石的后成合晶，而是原始地幔岩熔融形成富铬岩浆的演化产物。

Taking the Late Mesozoic basic-intermediate dike swarms from this area as the main object, we have studied their Petrology, Geochemistry and Isotopic Chronology, and discussed the property of their magmatic source, tectonic setting and origin as well. The significant conclusions acquired are as follows: 1, The Late Mesozoic dike from the coastland of Fujian Province appears as clusters, intruding into the Late Mesozoic granite or volcanic rocks, and the lithologies are diabase, hornblende diabase and quartz-diorite etc, mainly diabase. The mode of their occurrence is mainly precipitous and they tend towards NE, approximately EW or NNE. The dike swarms did not suffer metamorphose or distortion, holding the stress state as the dike formed.

本论文以该地区晚中生代中–基性岩墙群为主要对象，研究了它们的岩石学、地球化学及同位素年代学等，对岩浆源区的性质、构造环境、成因等进行了讨论，获得以下重要认识： 1、福建沿海地区晚中生代中–基性岩墙成群产出，侵入到晚中生代花岗岩及火山岩中，岩性有辉绿岩、角闪辉绿岩和石英闪长岩等，以辉绿岩类为主，产状较陡，北东、近东西及北北东走向，大多未发生变质或变形，保持了岩墙形成时的应力状态。
