成矿的

It is believed that the iron, gold and cobalt ores in Kaxiutata were formed at different stages of the same ore_forming event, and the magnetite ores are products of the contact metasomatism between the magma and the strata, while the enrichment of the gold and cobalt resulted from the subsequent sulfide deposition at the meso_hypothermal stages.

The δ〓S value of pyrite, sphelerite and arsonopyrite is in the range of 4. 0‰ and -4. 2‰ with the highest frequency occurring around zero, indicating a uniformed sulfur source. The large variation and mainly negative values (0.2‰～-11. 3‰) of δ〓S for stibnite could be interpreted by isotope fractionation. The carbon isotopic characteristics exhibit a mixing nature of magmatic carbon and organic carbon.

矿床中的热液成因黄铁矿、闪锌矿和毒砂的δ〓S＝4.0‰—-4.2‰，呈塔式分布，δ〓S集中在0附近，表明其成矿体系具有均—化硫的同位素组成，而辉锑矿的δ〓S变化范围较大(0.2‰—-11.3‰)，除一个样品外均为负值，这是硫同位素分馏作用的结果。

The study of the geological characteristics, ore-forming condition and genetic type from the Pingdingshan gold deposit, shows that the cryptomerous diorite and dioritic porphyrite in different stages formed a vein rock zone with gold containing ore bodies in the area, and five vein ore bodies were blocked out by spreading out with the NNE direction in the field.

黑龙江嘉荫平顶山岩金矿床的地质特征、形成条件和成因类型的研究表明：矿区内不同阶段的细晶闪长岩、闪长玢岩形成一个含金矿体的脉岩带；矿床范围内圈定5条呈脉状沿北北东向展布的矿体；矿石类型为石英脉型和蚀变岩型；金以裂隙金、晶隙金和明金为主，以银金矿的形式存在，且主要与石英、黄铁矿、毒砂和水云母共生；成矿作用分为热液期及表生期，其中热液期又分为4个成矿阶段，即纯石英阶段，黄铁矿毒砂石英阶段，黄铁矿毒砂水云母石英阶段和石英碳酸盐阶段。

The writer carries on processing to the Laichau area ETM remote sensing phantom data with application digital image processing method, and has obtained the good effect. She has withdrawn the mineralization alteration information and strengthened the loop of wire phantom characteristic. She has verified the golden ore deposit was in the loop of wire structure connection, the junction cuts as well as the ring structure edge spot. With the aid of in the remote sensing study information analysis method, the writer withdraws the mineralization advantageous loop of wire structure from the remote sensing phantom, and uses the mineral resource appraisal analysis system MORPAS software developed by China University of Geology to linear structure quantitative, gained massive quota information related with the gold mineralization.

本文应用数字图像处理方法对莱州地区的ETM遥感影像数据进行处理，取得了较好的效果，提取出了矿化蚀变信息并增强了线环影像特征，已探明的金矿床均处于线环构造交汇、交切以及环形构造边缘部位；借助于遥感地学信息分析方法，从遥感影像中提取成矿有利的线环构造，并利用中国地大开发的矿产资源评价分析系统MORPAS软件对线性构造定量化，获取了大量与金矿化有关的定量信息。

It is exist that of a horizontal zonality of different types of ore deposit, namely: copper-- stibium,gold,fluorite-- troilite,clay-- iron-- manganese, It is proved by the studies of this project that boundary surface between Emeishan basalt and Maokou limestone in western Guizhou is a importent strata to form ore deposits It will be usefull for ore prospecting in future.

本项目论证了并提出了贵州西部峨眉山玄武岩与茅口灰岩的接触界面是一个重要的成矿与赋矿的层位，相信会对今后的找矿工作有一定的帮助。

By using these anomaly evaluation methods, we fail to have a good understanding of the superficial appearance and essence from the development and evolution of the petrogenetic and metallogenic system, and the constraining of anomalies by supergene factors, genetic mechanism of anomalies and geological-geochemical environment produced by anomalies are less studied and only the information of the anomaly itself is extracted and used.

这些异常评价方法缺乏从成岩成矿系统的发展演化上去认识异常的表象与本质，关于表生因素对异常的制约和异常形成机制及异常产生的地质-地球化学环境的研究不够，只是提取和利用异常本身的信息。
