1. During diagenetic process , there may exist the fractional crystallization of clino - pyroxene , plagioclase , olivine and ti - fe oxide , and the accumulation of olivine . the alkalic - ultramafic dikes formed by low degree partial melting ( 3 . 4 % ) of enriched mantle , consist of single olivine pyroxenolite , the dominating olivine fractionation is evident
   成因上为富集地幔部分熔融作用的结果，但在成岩过程中也可能存在单斜辉石、斜长石、橄榄石和ti - fe氧化物等矿物的分离结晶作用。
2. The microscopical observation proves that the main types of granitoid rocks are granodiorite and quartz monzodiorite , and the enclave is mainly monzodiorite . the rock - forming minerals are mainly k - feldspar , plagioclase , amphiboie , biotite , quartz , magnetite , titanite , apatite , epidote , etc . the zonation of the feldspars is very popular . the dark - colored minerals , such as biotite and titanite , have been highly oxidized
   通过对本区花岗岩类样品进行显微观察研究，知其主要的岩石类型为花岗闪长岩、石英二长闪长岩，其中的岩石包体主要为二长闪长岩，其造岩矿物为钾长石、斜长石、角闪石、黑云母、石英、磁铁矿、榍石、磷灰石和绿帘石等，长石中环带现象比较常见，黑云母、榍石等暗色矿物颜色较深，表明其氧化程度较高。
3. The main characters of the thermal fluid activity are recognized as follow : many types and stages of veins are widely developed ; vitrinite reflectivity of different areas varies apparently with the depth ; there was a high temperature field during the formation of the thermal fluid , meanwhile , the volcaniclastic rocks were modificated by the thermal fluid activity , for example , sericitization of plagioclase , chloritization of volcanic detritus in andesitic detris tuff ; in the tufaceous mud , the thermal fluid activity accelerates " maturating " of the organic carbon by heating ; and the trace elements show an anomaly in the wall rocks
   同时，受热流体活动的影响，热流体对火山碎屑岩具有一定改造作用，如在安山质岩屑凝灰岩中，斜长石绢云母化、火山岩岩屑绿泥石化明显；在凝灰质泥岩中，热流体对围岩中有机碳具有明显的“催熟”加热作用，微量元素则出现异常现象。
4. The main element analysis of whole rocks , the ree analysis and the trace element analysis have been done for the granitoid samples in this area . the chemical composition analysis has been done for the amphiboie and biotite minerals . the epma and x - ray powdered crystal diffraction have been done for k - feldspar , plagioclase , amphiboie , biotite , quartz , magnetite , titanite
   对本区花岗岩类样品进行了全岩主量元素、稀土元素及微量元素分析，对角闪石和黑云母单矿物进行了化学成分分析，对钾长石、斜长石、角闪石、黑云母、及石英、磁铁矿、磷灰石和榍石进行了电子探针和x射线粉晶衍射分析。
