构造角砾岩

矿石类型以含金方解石-石英复合脉为主，其次为含金构造角砾岩型和含金蚀变岩型。

The major ore type is gold-bearing calcite-quartz vein , secondly is gold-bearing tectonic breccia , and gold-bearing altered rock .

文登金矿是受脆性剪切带控制的构造角砾岩碎裂岩型金矿床，是脆性剪切作用形成的，为典型的动力成岩成矿。

The Wendeng gold deposit is a tectonic breccia cataclastic rock type gold deposit dominated by brittle shear zone and formed by brittle shearing . It belongs to the typical dynamic mineralization and diagenesis .

矿体顶板围岩主要为构造角砾岩和闪长岩，底板围岩一般是云母斜长变粒岩。

Country rock in floor of ore bodies is generally mica-plagioclase leptynite .

主要工业矿体受层间滑动构造角砾岩带控制。

The gold orebodies were controlled by main slip fault zone - structural breccia rock zone .

近矿围岩为含碳千枚岩，赋矿岩石为构造角砾岩。

The host rock is a tectonic breccia , the proximal enclosing rock is C phyllite .

据各类型角砾岩的成因及特征，总结了含铅锌矿角砾岩是由同沉积断裂角砾岩、滑塌角砾岩和构造&岩溶角砾岩组成的复成因角砾岩。

Accord ing to the geneses and characteristics of various types of breccia it is summed up that the Pb Zn ore bearing breccia are polygenetic breccia consisting of synsedimentary faulting breccia , slip breccia and structural karst breccia .

前言：兰坪金顶超大型铅锌矿容矿角砾岩分为两类：一是构造-膏溶角砾岩，不含矿，胶结物孢粉组合显示晚三叠世特征；

The host breccia of the Jinding Lead-Zinc deposit are divided into two types : ① structural gypsum breccia containing no ore , palynoflora association of whose adglutinate reveals Late Triassic ;

据围岩和构造条件将矿体分为次火山隐爆角砾岩类、接触带－构造角砾岩类和围岩中断裂构造角砾岩等3种类型。

According to the wall rocks and structural conditions the ore bodies may be divided into three types : subvolcanic_cryptoexplosion breccia type , contact zone_ structural breccia type , and wall rock_ structural breccia type .

另外穿脉巷道中，由于成矿后期构造作用，矿体顶板和底板均为被晚期方解石脉贯入的构造角砾岩，这给巷道的稳定性带来威胁。

In addition , the top and bottom of laneway are filled with calcite and formed breccia due to the later tectonic process in ort laneway , which not only result in dilution of ore , but also bring about much threat to the stability of laneway .
