摘　　要：下坂金矿位于中国东南沿海中生代陆相火山岩带之中,是近年来勘查的金矿床。通过对矿床的地质学、矿床学、地球化学等特征的研究,该矿床成因上与流纹斑岩关系密切,具有广义斑岩型矿床特点。The Xiaban gold mine is situated at the Mesozoic volcanic zone of continental facies in the coast area of Southeast China and is one of gold deposits discovered in recent years in Fujian Province. Based on the characteristics of geology, mineral deposit and geochemistry for the Xiaban gold deposit, it is considered that the Xiaban gold deposit has a close relation with the rhyolite porphyry and is provided with the characteristics of generalized porphyritic type deposits.
