重砂测量是一种简便、经济、收效显著的找矿方法。在豫西用以找金,其效果更为突出。近年来,用化探方法在豫西圈出了一些有意义的金异常,其中有些与过去1:20万或1:5万重砂测量中所圈定的异常重合较好,在客观上起到了重砂与化探相互验证的作用。由于重砂法直接研究有用矿物的机械分散晕的分布规律及其特征,进而指出找 Heavy sand measurement is a simple, economical and effective method of prospecting. To find gold in the western Henan, the effect is more prominent. In recent years, some significant gold anomalies have been excavated in the west of Henan Province by the method of geochemical exploration, some of which coincide well with the anomalies defined in the past 1: 200,000 or 1: 500,000 heavy sand measurements and objectively The role of heavy sand and geochemical exploration in mutual verification. As the heavy sand method directly study the distribution of useful minerals scattered mechanical halo and its characteristics, and then pointed out that to find
