Depth of or e deposit formation and prognosis of deep- seated or e deposits.Geological Bulletin of China, 2007, 26(12):1509- 1518Abstr act: This paper deals with the depths of mineralization and vertical range of metal precipitation of different endogenic ore deposits.The lower limit of the depth of hydrothermal mineralization may reach 10- 12 km below the surface. The depth ranges of differenttypes of deposit are closely related to the characteristics of particular geological structure and magmatism at the time of mineralization,and the ore deposits show a very large variation space. The depth of metal deposit formation is constrained by the depth ofemplacement of parent ore magmas, while the depth of magmatic emplacement is in turn related to such factors as the quantity ofvolatile components in parent magmas, fluid separation time and partitioning coefficients between minerals and melts and between hydrothermalfluids and melts. Thus, we may explain the differences in mineralization depths of porphyry Cu (- Mo) deposits, porphyryMo (- Cu) deposits and porphyry W deposits. The depths of mineralization are also related to geothermal gradients and permeability ofporous rocks. Because the solubility of volatiles such as CO2 is very sensitive to pressures, the use of the fluid inclusion geobarometercan be considered to determine the depth of mineralization. During prognosis and prospecting of deep- seated granite- related polymetallicore deposits, it is important to look for the top belt or cupola of hidden intrusions.Key words: Formation depth of ore deposits; prognosis of deep- seated ore deposits; hydrothermal ore deposit; top belt and cupola;hidden intrusion at depth全国重要矿产和区域成矿规律研究进展综述内容提要：对重要矿产开展全国性的资源潜力评价，是国情调查的重要组成部分，而开展重要矿产和区域成矿规律的研究，又是矿产资源潜力评价的基础性工作。自年的年间，通过对多个典型矿床的野外调查，开展了典型矿床和区域成矿规律的全面研究，编制了成矿规律研究的技术要求，组织了全国性的技术培训，指导了大区和省级项目成矿规律研究工作，完成了大区和省级项目典型矿床和成矿规律研究成果的验收、汇总和综合，编制了全国单矿种（组）成矿规律相关专题图件，建立了相应的数据库，提出了一系列新认识、新技术和新方法，包括同位素定年的方法和成矿规律编图方法，为矿产资源潜力评价奠定了扎实了理论基础，有效地指导了潜力评价和地质找矿工作，培养了人才，锻炼了队伍，取得了良好的经济效益，显著地提升了我国成矿学的研究水平。关键词：矿种成矿规律；区域成矿规律，潜力评价；成矿预测；研究进展：， （），：；若干成矿预测理论研究综述王明志, 李闫华, 鄢云飞, 李艳军(中国地质大学资源学院, 湖北武汉430074)摘要:成矿预测研究一直是矿床勘查研究的热点, 对现代矿产勘查与评价实践具有重要的指导意义。近年来据成矿预测理论的研究进展, 对相似类比预测理论、地质异常预测理论、成矿系列理论及成矿系统理论、矿床成因模式理论、综合信息成矿预测理论等研究现状及进展进行了全面的综述, 概述了成矿预测理论发展的趋势,认为未来一定时期内, 成矿预测方法研究将会向定量化、精细化方向发展, 深部隐伏矿床(体)的“定位” 预测是主要的研究方向。关键词:成矿预测理论;定量化;精细化;矿体定位预测中图分类号:P612 文献标识码:A文章编号:1671 -1211(2007)04 -0363 -07OverviewofResearchforMetallogenicForecastingWANGMing-zhi, LIYan-hua, YANYun-fei, LIYan-jun(FacultyofEarthResources, ChinaUniversityofGeosciences, Wuhan, Hubei430074)Abstract:There search of metallogenic forecasting theory which has important indicating significance for todays exploration and evaluation for mineral resources has been one hotspot in these fields.Base dupon the progress in theory of Metallogenic forecasting in recent years,the theories such as similarity and analogy forecasting theory, geo-anomaly forecasting theory,Metallogenic series theory, metallogenic system theory, mineralization mode theory and information contentMetallogenic forecasting theory are summarized comprehensively in the paper, which is the tendency of these developingTheories with some suggestions.The investigative methods of metallogenic forecasting theory are considered to be quantitative and available in the future.At the same time, the ore body location forecasting of deep concealed ores will comingThe main investigative goal.Keyword:metallogenic forecasting theory;quantitative;fine;ore body location forecasting我国深部找矿研究进展综述曹新志a , 张旺生b , 孙华山a(中国地质大学a .资源学院;b .地球科学学院, 武汉430074)摘要:进入21 世纪以来,深部矿已成为我国矿产勘查的重要对象,从而标志着矿产勘查进入了一个新的阶段。由于深部矿相对浅部矿具有埋深大、矿化信息弱、综合地质研究程度低的特点,使传统成矿理论的指导作用和勘查技术方法应用的有效性受到较大的影响,造成深部矿勘查的难度加大。为了减少深部矿勘查的盲目性和风险性,人们重视和加强了深部找矿地质成矿理论和技术方法的研究,并取得了一定的进展。研究资料表明,成矿系统、第二矿化富集带、矿床成矿深度厘定、矿床深部成矿特征、矿田深部构造以及深部找矿前景的定量评价等研究内容已成为当前我国深部找矿工作中地质成矿理论研究的热点,大深度物探技术和深穿透的化探新方法、高分辨率航卫遥感技术以及大深度的钻探技术等方法的研制和应用已成为深部找矿技术的发展方向。关键词:深部找矿;成矿理论;技术方法;研究进展中图分类号:P62 文献标识码:A 文章编号:1000-7849(2009 )02-0104-06Progress in the Study of Deep Exploration in ChinaCAO Xin-zhia , ZHANG Wang-shengb , SUN Hua-shana(a .Faculty o f E arth Resources ;b .F aculty o f E arth S ciences , ChinaUniv ersity of Geosciences , Wuhan 430074 , China)Abstract :In this century , deep mineralization has become an important object of mineral explo ration inChina , th
