一、岩体地概况 (一)地质特征位于山东省沂源县东南部韩旺、张家坡一带的韩旺花岗岩,呈北北西——南南东向展布,长22公里、宽1—4公里,面积约55平方公里(图1)。该岩体侵位于泰山群雁翎关组各种混合岩、变质岩之间,形态极为复杂。除主体(约20平方公里)外,大都(尤其是边部)呈不规则的枝状、条带状穿插体,主体内亦大量产出围岩残留体。岩体,包括各种穿插体与残留体的展布方向与泰山群变质岩系的片理、片麻理一致。
I. Overview of Rock Mass (I) Geological Features The Hanwang granite is located in the Hanwang and Zhangjiapo southeastern part of Yiyuan County, Shandong Province. It is a north-west-south-south-east distribution with a length of 22 kilometers and a width of 1-4 kilometers. An area of about 55 square kilometers (Figure 1). The rock body invaded Taishan Qunling Yan Ling Guan various mixed rocks, metamorphic rocks, the form is extremely complex. In addition to the main body (about 20 square kilometers), most of the (especially the side) was irregular dendritic, strip-like interlacing body, the body also produced a large number of residual rock mass. The distribution direction of the rock mass, including various interspersed bodies and remnants, is consistent with that of the Taishan Group metamorphic rocks.
