摘要: 河南省商城县汤家坪钼矿为典型的花岗斑岩型钼矿床,花岗斑岩体具有超酸、富碱、高钾的特点,钼矿化与钾化、硅化关系密切。对应钼矿范围出现较强的Mo异常,ΔT表现为相对负磁异常。根据矿床地、物、化特征建立了花岗斑岩型钼矿综合找矿模式,依照模式寻找到半隐伏大型钼矿床1处,并客观评价了国内多个Mo异常,取得了较好的应用效果。Abstract: The Tangjiaping granite?porphyry type molybdenum deposit in Shangcheng County of Henan Province is a typical granite?por?phyry type molybdenum deposit with ultra?acid, alkali?rich and K?high characteristics. Molybdenum mineralization is closely related to potash alteration and silicification. Relatively strong Mo anomaly is consistent with the extent of the molybdenum deposit, and ΔT ex?hibits relative negative magnetic anomaly. Based on geological, geophysical and geochemical characteristics, the authors established an integrated ore?prospecting model for the granite porphyry type molybdenum deposit and, on such a basis, found a semi?concealed large molybdenum deposit and objectively evaluated quite a few Mo anomalies in China, thus achieving fairly good application results.
