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...

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 ore-forming materials of the deposits at Wubu, Dalingkou and others are considerd to be from upper mantle and lower crust on the basis of the isotopie characteristics of sulfur, lead, hydrogen anb oxygen in southeast Zhejiang. The ore-forming hydrothermal fluid was predominated with the magma tic water early in the oreforming processes.and then meteoric water prevailed.Mineralization was associated with subaerial vokanism of Mesozoic age. The ore-forming materials of the deposits of Qiwan, Niaoao, Zhitouling...

The ore-forming materials of the deposits at Wubu, Dalingkou and others are considerd to be from upper mantle and lower crust on the basis of the isotopie characteristics of sulfur, lead, hydrogen anb oxygen in southeast Zhejiang. The ore-forming hydrothermal fluid was predominated with the magma tic water early in the oreforming processes.and then meteoric water prevailed.Mineralization was associated with subaerial vokanism of Mesozoic age. The ore-forming materials of the deposits of Qiwan, Niaoao, Zhitouling and so on were derived from the metamorphic rocks of Chencai Group. The medium water of ore-forming hydrothermal fluid was predominated with the metamarphic water trapped during the metamorphism period of the primary rocks of Chencai Group. The mineralization was also associated with the metamorphism in Caledonian pericd.

本文根据浙东南地区两类铅锌(银)矿床的硫、铅及氢氧同位素特征,认为:五部、大岭口等矿床的成矿物质主要来自上地幔及下地壳:在成矿作用早期的成矿热液以岩浆水为主。晚期则主要为大气降水:成矿与中生代陆相火山作用有关。七湾、乌岙、治头岭等矿床的成矿物主要来自陈蔡群变质岩:成矿热液中的介质水,主要为陈蔡群变(?)成矿与加里东期变质作(?)

Rare metals deposits related to volcanism can be classified into 3 genetical types , namely ,rare melals-bearing volcanites deposits, post volcanic hydrothermal deposits and volcanite-weathered deposits. The controlling factors of endogenetic mineralization can be preliminary discussed from the condition of volcano-magmatism, volcano-tectonic and stratigraphic country rocks . It is pointed out that volcanite type rare metal deposit would be prospective in China.

陆相火山作用有关的稀有金属矿床可划分为三种类型,即含稀有金属火山岩矿床,火山期后热液矿床和火山岩风化矿床。从火山岩浆作用、火山构造及围岩地层成矿条件,初步探讨了内生成矿控制因素,并指出火山岩型稀有稀土矿床在我国具有找矿前景。
