赣北九岭成矿带昆山钨钼铜矿床地质特征

Geological Characteristics of Kunshan W-Mo-Cu Deposit in Jiuling Metallogenic Belt in Northern Jiangxi

昆山钨钼铜矿床是近几年在赣北九岭成矿带发现的系列矿床之一,是一个以石英细脉带型为主的矿床。矿体主要赋存在岩体外接触带的双桥山群浅变质岩中。在南区,钨、钼紧密共生,组成钨钼复合矿体,并具有上钨下钼的特点;在中区,则以铜矿体为主。矿体多呈隐伏状,部分出露地表。矿体形态较复杂,呈复脉状、脉状。矿石类型主要有钨矿石、钼矿石、铜矿石和钨钼矿石。主要有用矿物为黑钨矿、白钨矿、辉钼矿、黄铜矿等。矿床的主要成因类型是外接触带细脉带型矿床。

Kunshan W-Mo-Cu deposit is mainly a quartz veinlet belt type deposit, which has been prospected in recent years in Jiuling metallogenic belt in northern Jiangxi province. Ore body mainly occurred in quartz veinlet belt which located in outer contact. Cu and Fe minerals are closely associated and form the compound ore bodies in the north section, while ore bodies are formed mainly by Cu minerals in central section. Most of the ore bodies are concealed and part of them outcrop. The major useful minerals which form ore bodies are wolframite, scheelite, molybdenite and chalcopyrite. The genetic type of the deposit is meso-hydrothermal and quartz veinlet belt.
