本岩体中橄榄石矿物特征的研究资料已有较多的记载,尤其是最近几年,又更多地描述了橄榄石晶体的方位定向性,以及该矿物的带状消光和笔者提出的2V值异常等应力作用特征。反映了橄榄石矿物是在一定的物理化学条件中受应力作用而形成的,并且这种应力作用所形成的痕迹(系指晶体定向、带状消光和2V值异常),在橄榄石矿物中永久地保存下来了。本文对橄榄石矿物晶体所受应力作用的机制进行了分析讨论,并结合岩体地质概况提出本岩体的最终侵位方式是冷侵位的见解。应当指出,笔者仅仅是着重从岩体侵位过程的应力特点出发,而不过多地涉及其它地质因素。由于笔者水平有限,以及超基性岩体侵位方式
The olivine mineral characteristics of the rock body has more information on the research records, especially in recent years, more description of the orientation of the olivine crystal orientation, and the banded extinction of the mineral and the author proposed 2V Abnormal value and other stress characteristics. Reflecting that olivine minerals are formed under the stress of certain physico-chemical conditions and that traces of this stress action (referred to as crystal orientation, banded extinction and 2V anomalies) are permanent in olivine minerals Saved. In this paper, the mechanism of the stress on the olivine mineral crystal is analyzed and discussed. Based on the geology of the rock mass, the final emplacement mode of this rock mass is the opinion of cold emplacement. It should be pointed out that the author only focuses on the stress characteristics of the emplacement process of the rock mass rather than involving other geological factors. Due to the limited level of author and the emplacement of ultramafic rocks
