摘　　要：通过1988—1990年对前期保存的岩心进行重新取样分析测试,发现了达到工业品位的金的赋矿有利地段。实物地质资料的二次开发对该矿的找矿突破起到了关键作用。此后开展的几次勘查成果,保守累计至少金属资源量达到中-大型规模,经济效益显著。对该矿的成矿地质特征及成因进行了分析,指出了找矿方向。该实例表明,随着找矿理论的不断深入,通过研究周边已知矿床成矿模式及控矿条件,运用相似类比方法,科学开发已有的实物地质资料,是实现找矿突破的有效途径。This paper describes in brief more than 30 years＇ prospecting process in the Xianren rock gold deposit of Changning, Hunan Province, since 1978. Especially, through re-sampling and analyzing of the past cores preserved from 1988 to 1990, the target gold-bearing area reaching gold industrial grade was found. During the process, second-round development of geological samples played a key role in finding the gold deposit. Thanks to the multi-times explorations since then, the metal resources of the deposit have arrived the middle to large scale at least and the economic benefit is remarkable. This paper analyzed the metallogenic geological characteristics and genesis of the gold deposit, and pointed out the direction of ore-prospecting. The case study demonstrates that the second-round scientific development of geological samples is an effective way to realize prospecting breakthrough, with the deepening of the prospecting theory and by studying the known ore deposit metallogenic model and ore-controlling conditions as well as using similar analogy methods.
