摘　　要：豫西是中国重要的金、银、钼、铅锌及多金属产地,近年来不断有新的矿床陆续被发现,多位专家学者对该区的资源量预测差异较大。本文运用地球化学块体理论,通过对区域化探数据的处理和计算,划定豫西金地球化学块体边界,计算了金、钼各含量级别对应的地球化学块体的面积、可供金属量和成矿率。通过计算预测豫西金资源量,分别预测得到豫西Au资源总量为2 445 t,Mo资源总量为1 110万t,目前探明储量占预测资源量的比例还很小,与世界同等级别异常的矿集区相比,其探明资源量明显偏低,资源潜力可观。Western Henan is an important base area of China＇s gold,silver,molybdenum,lead,zinc and polymetallic resources.In recent years,new ore deposits have been discovered in succession.Geologists＇ estimations of resources quantities in this area are quite different from each other.On the basis of geochemical blocks theory and through regional geochemical data processing and calculation,the authors delimited the boundaries of western Henan gold geochemical blocks and calculated their areas,amounts of metals available and mineralization rates according to different levels of gold,molybdenum content.Using calculating method to predict the amount of gold resources in western Henan,the authors obtained 2 445 t for total gold amount and 11.1 million tons for molybdenum.At present,proved reserves account for a very small proportion in forecast resources.Compared with anomaly ore-concentrated areas of the same level in the world,the proved resources of this area are obviously low.Therefore,it has considerable resource potential.
