国外典型矿床发现规律与启示

通过对70个国外典型矿床发现史的研究,总结出国外矿床发现的一些规律:(1)公司在矿床勘查过程中起主要作用,地调机构在勘查中也起了重要补充作用;(2)理论上讲,矿床勘查遵循循序渐进的勘查程序,市场经济体制下的勘查实践反映勘查行为往往跨越式进行,满足在技术要求可行条件下的勘查效益最大化;(3)资料再开发、老矿区外围找矿具有较大的成功率;(4)综合勘查技术的应用在矿床勘查中起着十分重要的作用;(5)矿床勘查具有高风险和长周期,勘探工作需要进行锲而不舍的努力;(6)不同形式的联合勘查是取得勘查成功的重要保证.此外,该文还对我国的矿产勘查也提出了若干启示和建议.

DISCOVERING RULE AND INSPIRATION OF OVERSEAS TYPICAL DEPOSITS

Based on the research and analyses on 70 overseas typical deposits,the rules of discovering history for these overseas deposits were summarized: (1) In the course of ore prospecting,companies play a main role and geological investigation institutions take on supplement;(2) Although there is a gradual procedure in geological prospecting in terms of theory,the practical procedure under market system is often anomalous because prospecting organizations want most benefit;(3) Further data exploitation and looking for ores in the periphery of old mines are shortcut for deposit discovering;(4) Comprehensive prospecting technology has a very important effect;(5) The ore prospecting requires perseverance because of its high venture and long period;(6) multifarious combined prospecting is an important for successful reconnaissance. Some good inspiration and advises for Chinese mining were also put forward in the paper.
