摘　　要：德化县东洋矿区金矿位于东南沿海中生代火山岩带中,为近年来发现的规模较大的金矿床。矿体主要赋存于次流纹斑岩及外接触带附近,为火山-次火山热液型金矿床。矿体呈不规则状、透镜状和脉状,矿石组分简单,品位偏低,工程控制和推(预)测金金属量可达大型,随着找矿勘查工作的深入,区内金矿规模将会进一步扩大。The Dongyang gold deposit in Dehua County of Fujian Province occurs in the Mesozoic volcanic rock belts of Southeast Coast in China, and is a recently discovered large-scale gold deposit. The orebodies are mainly hosted in subvolcanic rhyolite porphyry or near the outer contact zone, and this deposit is a volcanic-subvoleanic hydrothermal one. The orebodies show irregular, lenticular or veined shapes; the ores have simple composition, with a low gold grade; and the engineering-controlled and predicted metal amounts of gold have reached a large scale. With the increasing exploration work, the scale of this deposit is expected to be larger.
