摘要
自然重砂测量是矿产勘查的最直接手段,在实践中能够有效揭示找矿线索。吉林省开山屯铬铁矿床具有悠久的开采历史,通过对与基性—超基性岩密切相关的开山屯铬铁矿床的标型矿物,即铬铁矿、黄铁矿、自然金、辰砂等自然重砂矿物的统计分析,异常的空间分布特征以及空间组合特征,全面展示了开山屯铬铁矿床自然重砂矿物异常的规律性。并结合该矿床化探异常的综合研究,确定了铬铁矿重砂异常的矿致性质以及重要的找矿指示意义。同时建立起开山屯铬铁矿床的重砂找矿模式,并对模型进行了初步探讨。
Heavy minerals survey is a direct prospecting which can reveal clues to ore deposits. Kaishantun chromite deposit has a long mining history. This paper, based on a study on its typomorphic minerals related to basic to ultrabasic rocks, chromite, pyrite, natural gold and cinnabar by their anomaly spatial distribution and combination, combines with chemical prospecting to determine the heavy mineral anomaly and its indication, and establishes a heavy minerals prospecting model of Kaishantun chromite deposit.
