摘要
蔡家坪铅锌矿位于著名的北武夷铜铅锌银多金属成矿带内，矿体主要赋存于侏罗系下统水北组层间破碎带内—大致顺层侵入的流纹斑岩与围岩接触带和流纹斑岩墙或斑岩脉内、外接触带中。矿体呈透镜体状、带状。不同成因矿体的产状差异较大，产状在20~75°之间。矿体主要金属矿物组合为方铅矿、闪锌矿、黄铁矿等。矿石构造以块状构造为主，次为细脉状、网脉状构造等。矿床属中低温火山沉积—层间破碎带—岩浆热液叠生型及次火山斑岩型矿床，属次火山热液矿床。
Caijiaping Pb-Zn Ore District located in the famous North Wuyi polymetallic metallogenic belt of Cu, Pb, Zn and Ag. Ore bodies mainly occur in the Jurassic North Water Group under the EC rhyolite porphyry and the inner and outer contact zone. Ore bodies are lentoid or stripped, and there is great difference at attitude of ore bodies with different genesis, which has inclination between 20~75°. Ore bodies composed with galena, sphalerite, pyrite, etc. Structure of ore mainly is massive, next for veinlet and stockwork. The ore district belongs to the low temperature volcanic-interlayer fracture zone-the magmatic hydrothermal-sub volcanic porphyry type deposit, which belongs to the sub volcanic hydrothermal deposit.
