摘　　要：综述了成矿预测研究中不利预测因素与标志的含义、作用。不利预测因素与标志是指对矿床的形成、保存和找寻具有明显不利影响的有关预测因素和预测标志。不利预测因素包括不利的构造因素、不利的岩浆岩因素和不利的岩相古地理因素以及不利的变质作用。不利的预测标志包括不利的地球物理、地球化学异常标志,不利的预测标志包括不利的地球物理、地球化学异常标志,不利的围岩蚀变标志和不利的矿物学标志。对不利预测因素与标志的研究可以从不同的侧面认识、分析有关预测找矿的地质问题,从而在开阔预测思路、提高预测效率和降低勘查成本等方面起到有益的作用。This paper summarizes the significance and effect of adverse forecasting factor and indicator in metallogenic forecasting research. Factor and indicator of adverse forecasting indicates related forecasting factor and indicator which have distinct adverse influence to the formation , preservation and prospecting of ore deposits . Adverse forecasting factor includes that of adverse structure, adverse magmatic rock , adverse lithofacies paleogeography and adverse metamorphism. Adverse forecasting indicator includes that of adverse geophysical and geochemical anomaly, adverse wall rock alteration and adverse mineralogy. According to the adverse forecasting factor and indicator , the metallogenic forecasting is analysed from different aspects. This research will provide beneficial reference to widen the trend of thoughts , guide prospecting and exploration , improve efficiency of forecasting and lower prospecting cost.
