Sanmen volcano-tectono-depression is located in the north of the volcanic are in the coastal margin of Zhejiang-Fujian-Kuangdong provinces. In the depression there are over 50 mineralizations of iron, lead, zinc, copper, manganese, silver, molybdenum and sulphur. They are mainly volcano-sedimentary origin with late hydrothermal modification, such as Longchushan lead-zinc deposit in Linghai and Lijin iron-lead-zinc deposit in Sanmen. They are strictly stratabound. Orebodies are situated in the layer with definite rock assemblages. The composition and texture-structure of ores possess characteristics both of volcano-sedimentary and hydrothermal imprints. Wallrock alterations are mainly silicification, skarnization, chloritization etc.. showing vertical zoning. The formation of ore deposits can be subdivided into 3 stages, i. e. volcano-sedimentary stage, volcano-hydrometamorphic stage and volcano-hydrometa-somatic stage, thin mineralization temperatures are correspondingly 100~13℃, 200~400℃ and 230℃. The δ(34)S=+4~3‰ are

浙江三门中生代火山——沉积盆地的形成演化可分四个阶段。每一阶段均伴产有不同成因和各具特色的金属矿床,显示了陆相火山作用较为完整的成矿体系。其中层状矿床具有同生和后生的双重特征,多成因,多来源,是较典型的火山沉积——后期热液迭加改造型矿床。本文着重介绍它的主要特征及盆地的形成演化对火山成因矿床的控制。

The coastal region of southeast China is located in outer zone of middle part of the west pacific Metallogenic Zone. In this region are extensively distributed Mesozoic volcanic ore deposits and the zonation in both directions are observed. From south to north the assemblages zones of ore deposit Perpendicular to the coast are rare metals and REE-polymetal.

中国东南部中生代陆相火山金属矿床在空间上具特征的纵向与横向分带。平行海岸线的矿床组合分带由南东向北西,依次为铜带、银铅锌带(局部有铁、钼、稀有金属和金)、金银、铀带、稀土金属和铀带,它们受控于火山活动期的大地构造性质、火山物质来源和岩浆演化过程;垂直海岸线的横向分带由南向北依次为稀有和稀土金属带、多金属带,它们受控于基底构造层的大地构造性质、物质组分及区域地球化学背景场等条件。

The recently proved Lengshuikeng Pd—Zn—Ag Orefield has a huge amount of reserves and consists of three types of mineralization (porphyry. veined and stratabound-telescoped),With metallogenetic features of multiple genesis and a three in one combination in ore types.

冷水坑矿田是我国近年来探明的一个特大型铅锌银矿田。成矿类型有斑岩型、脉带型和层控叠生型等三种,具多成因、多位一体的成矿特点,它的形成与我国东部中生代陆相火山活动的火山喷气—热液作用有关矿田地处孤萝山破火山口西侧断陷带内,呈北东—南西向展布。北东向及其配套断裂和燕山中期的次火山岩体均较发育,是重要的成矿和控矿条件。花岗斑岩呈舌状侵位于侏罗系上统鹅湖岭组(J,e)地层,位于F_2逆断层的下盘,是斑岩型和脉带型矿床的主要含矿围岩。层控叠生型矿床的赋矿围岩为侏罗系上统打鼓顶组下段(J,d~1)顶部的石英正长质火山角砾岩层。矿体呈层状、似层状、透镜状,严格受层位控制。矿田中除铅、锌、银外,伴生组份S、Cd、Au、Cu、In等均具综合利用价值。
