脉岩

This dissertation focus on rutiles, apatites epidotes and vein minerals from CCSD drill core and outcrops of Sulu-Dabie UHPM rocks, by detailed study of petrography, petro-chemistry, and mineral-chemistry, the implication of these minerals to UHPM and continental subduction-exhumation were discussed.

大别地表超高压变质岩中的这些副矿物和脉体矿物为主要研究对象，通过详细的岩相学、岩石化学、矿物化学等研究，对这些副矿物在超高压变质作用及大陆深俯冲—折返过程的指示意义进行了较为深入的探讨，在以下几个方面取得新的认识：1。

Serpentine rock is primarily composed of one or more magnesium silicate minerals such as chrysotile -- often occuring as fibrous veinlets in serpentine, the most common type of asbestos which separates into thin, strong, and flexible fibers that are heat resistant.

蛇纹石岩主要是由一种或更多种镁硅酸盐矿物，如温石棉-蛇纹石纤维中常见的细脉，其中的石棉形成薄的，坚韧，有弹性的耐热纤维分隔层。

Along with the increasing distance from the main ore-controlling structures, or from the deeper to shallow parts of an ore body, the species and content of metallic sulphides seem to increase.

随远离主干断裂或由矿体的深部到浅部，金属硫化物的种类和含量呈升高的趋势，往往由少硫化物蚀变岩型向多金属硫化物石英脉型转化，矿脉中的上部矿体或同一矿体的上部，金属硫化物的种类和含量较高，这种变化规律和矿脉的地球化学特点是吻合的。

There are two types of gold deposits in this area, namely altered rock type and quartz vein type.

本区金矿床包括两种类型：柴胡栏子金矿床为蚀变岩型金矿；莲花山和红花沟金矿床属石英脉型。

The quartz vein and altered rock types of gold deposits, with similar geological environments, ore-constraints and distribution laws, predominate in the belt.

石英脉型、蚀变岩型金矿是带内主要的矿床类型。它们的产出地质环境相同，成矿控制条件及时空分布规律相类似。

Daqingshan gold deposit is a Carboniferous carbonaceous-rock-hosted quartz vein type.

大青山金矿是产于石炭系炭质岩系中的石英脉型金矿。

The ore-control structure can be divided into two types which are transtension fracture and transpression fracture. The former controls quartz vein ore, and the latter controls altered rock ore.

控矿构造可分为两种类型，既压扭性和张扭性，前者控制着蚀变岩型矿体分布，后者则控制着含金石英脉型矿体分布。

The species and abundance of metal minerals increasing from SE to NW in horizon, corresponding transformation from sulfide altering orebody type to quartz vein orebody type.

同时在矿田水平方向上，由于SE→NW金属矿物的种类和含量呈增加的趋势，由少硫化物蚀变岩型向多金属硫化物石英脉型变化。

Furthermore, the rock-forming and ore-forming process of the deposit is featured by multi-stage and multi-phase superimposing, and the process of ore-forming is coupling with the process of rock-forming.

今后的深部找矿工作尤其是杨梅岭矿段深部应该注意寻找两个时期分别形成的石英脉型和矽卡岩型矿体。

According to a vast amount of geochemical research works on gold deposits , some sedimentary-exhalation type gold deposits have been distinguished. In addition, the close spatial and temporal relation of sedimentary-exhalation to the Archaean lode gold deposits that have distinct characteristics of epigenetic mineralization also has been discovered.

大量的金矿床地球化学研究工作已识别出一些沉积喷流型金矿床，此外还发现即使是具有明显后生成矿特征的太古宙绿岩带中的脉状金矿床也显示出其同沉积喷流作用密切的时空关系。
