统计国外13个铜-金矿床的勘查策略和技术方法可知,这类矿床要运用多种手段综合勘查:磁法、激发极化法、电阻率测量等物探方法;水系沉积物,岩石碎屑,土壤地球化学测量;地质填图,钻探方法验证异常等。中国的15个铜成矿带,绝大多数具有斑岩型铜矿,具备斑岩型铜-金矿床的产出环境,但目前这类矿床具有一定规模的却很少。在勘查策略方面存在着对伴生金资源的严重浪费,综合手段不够系统,也不够灵活的问题。在找寻、勘探、评价的策略上除应加强研究力度外,还要克服“施工一个钻孔就要得到一定储量”的倾向。
Statistics abroad 13 copper - gold exploration strategy and technology shows that such deposits to use a variety of means comprehensive exploration: magnetic method, induced polarization, resistivity measurement and other geophysical methods; sediments, rock debris, Soil geochemical survey; geological mapping, drilling method validation anomalies. Most of the 15 copper metallogenic belts in China have porphyry-type copper deposits, which have the production environment of porphyry copper-gold deposits. However, there are only a few such deposits at present. There is a problem of serious waste of associated gold resources and lack of systematic and flexible means of exploration in the exploration strategy. In the search, exploration, evaluation of the strategy should be strengthened in addition to research efforts, but also to overcome “construction of a hole will have a certain reserve ” tendency.
