角砾岩

This thesis has emphasized studies on forming mechanism of dioritic quenched enclaves in the subvolcanic dikes and cryptoexplosive breccia at depth of the Zoujiashan uranium deposit, systematically studied the diagenetic ages, geochemical characteristics and Nd, Sr, Pb and Lu-Hf isotopic compositions of the Xiangshan volcanicintrusive complex and mineralization at depth of the Xiangshan ore-field.

本文重点解剖了相山次火山岩中闪长质淬冷包体及邹家山富大铀矿床深部隐爆角砾岩的成因机制；系统研究了相山火山-侵入杂岩的成岩时代及其Nd、Sr、Pb和Lu-Hf同位素组成；同时还对相山火山-侵入杂岩的岩石地球化学特征及相山矿田深部的成矿作用进行了深入研究。

The hypo-volcanic crytoexplosion Breccia rock body and the felstone in the east-western shear zone are the important symbol of the exploration.

东西向脆－韧性剪切带内次火山隐爆角砾岩体、霏细岩脉的存在是区内重要的找矿标志。

Ore-bearing breccias can be divided into complete-pipe and compound mineralizing types in the east part of north Huaiyang tectonic zone , in which the former type keeps certain distance from the hypabyssal rock, the latter one is accompanied by the hypabyssal rock in space.

北淮阳构造带东段含矿角砾岩主要有全筒矿化型和复合矿化型两种，前者与浅成岩有一定距离，后者在空间上与浅成岩伴生。

The cryptoexplosion of gas and liquid is internal cause of cryptoexplosion breccia type and breccia type gold polymetallic deposits, lithogenesis and mineralization were the products of the same geological process of different stage.

隐爆角砾岩型金矿床是国内外一种重要的金矿类型，分布广泛，除大量的中小型矿床外，还有一些世界级的超大型矿床[7～ 8]、①。

The gold deposit types are com plicated,can be divided into five types;hydrothermal breccia gold deposit,similar beded disseminated gold deposit in limestone,old karst cave gold deposit,porphyry gold deposit and skarn gold deposit.The form of these gold deposits are related to Tongshi subvoleanie complex.

该区金矿形戚与铜石次火山杂岩体有关，区内金矿类型复杂，可划分为隐爆角砾岩带型金矿、似层状畏染状灰岩中金矿、古溶洞型金矿、斑岩型金矿、矽卡岩型金矿等5种矿化类型。

The mineralization-alteration in Shuangfengshan appears in downward succession of silica breccia zone, low grade gold-bearing silica rock zone, quartz stockwork zone, pyrite montmorillonite zone and propylitic alteration zone.

这两个成矿阶段同源同位的蚀变矿物晕叠套，造成双峰山矿床蚀变分带从上至下为隐爆矽质角砾岩化带、低金品位矽质岩带、石英网脉带、黄铁矿蒙脱石化带和青磐岩化带。

The Yiarmand gold deposit occurs in hydrothermally eruptive breccia of the 2nd Member of Lower Carboniferous Dahalajunshan Formation and its underlying arsenopyritized and pyritized tuffaceous clastic rocks,and the ore forming process can be divided into hydrothermally eruptive and sedimentary stage and metasomatic stage.

伊尔曼德金矿床赋存于下石炭统大哈拉军山组第二岩性段硅化热液喷发角砾岩及其下伏上泥盆统吐呼拉苏组毒砂黄铁矿化凝灰质碎屑岩中，成矿作用可分为热液喷发沉积期和热液交代蚀变成矿期。

Altered fracturezone type and quartz veitl type of gold deposits developed in the Qiyugou area of the eastern Qlnling fold zolle belong to a metallogenlc series relaied to the mid -- late Yanshania cafe--alkline granitoids.

该系列金矿是在燕山中晚期钙碱性花岗质岩浆基础上发育起来的，具有同源、同期、同成因、不同空间成矿的特征，称之为以隐爆角砾岩型为主的金矿床系列。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
