摘要
粤北城口—九连钨多金属成矿带位于北西向半隐伏—隐伏构造岩浆岩带和海西期隆拗过渡带。钨成矿与燕山第三期、四期花岗岩岩浆活动关系密切，成矿岩体同位素年龄97．5-157Ma。钨矿化类型复杂，其中石英脉型钨矿是主要矿床类型。根据该成矿带钨的成矿地质条件及找矿信息，目前除寻找石英脉（带）型钨矿外，还应寻找蚀变花岗岩型和矽卡岩型钨矿。
Chengkou-Jiulian tungsten polymetal minerogenic belt is situated in a NW spreading （semi-） buried tectonic magmatite zone and in a transitional area of up-warping and down-warping. The genesis of tungsten ore is in affinity to granite magrnatic activities in the third and forth periods of Yanshan circle. The isotopic ages of minerogenic lithosome are between 97.5 million years and 157 million years. The tungsten mineralization is in various types,in which quarz tungsten ore was the major deposit type. The authors suggest that ore prospecting attention should be paid to altered granite and skarn tungsten ores in addition to looking for quarz tungsten ore based on tungsten ore geology and prospecting information along the minerogenic beh.
