摘　　要：通过对白银矿田找矿勘探和再找矿历史的研究,分析不同时期的找矿思路,对以往找矿成功经验和失败的教训进行总结和反思,不仅有助于丰富地质找矿理论,也对当前条件下进行再找矿具有重要意义。尤其是近年来,在"海底火山机构-热卤水循环动力学"学术思想指导下,在白银矿田小铁山矿床西段(11-14线)深部和折腰山矿床深部发现新的富铜矿体,显示已有工业矿床,深部及其周边地段具有广阔的找矿前景,为进一步找矿提供了依据。By studying the history of prospecting and ore rehunting in Baiyin orefield and analysing the oresearch thinking at different periods, some successful experiences and failing lessons during the orehunting practice are sumed up Thus is not only enriched the geology and orehunting theory, but also layed a foundation for ore rehunting at present conditions Especially, under the guidance of academic thought 'Submarine volcanic apparatus-hot brine circulation dynamics' in recent years, new Curiched ore bodies have been discovered in the deep of the west segment of Xiaotieshan deposit, and in the deep of Zheyaoshan deposit, indicating that there is broad orehunting prospect in the deep of economic deposit existed and its surroundings The basis for ore rehunting is provided by renewal the ore hunting thinking
