赣南钨矿成矿特征与找矿前景

The Metallogenic Features and Ore-finding Potentiality of the Tungsten Deposits in South Jiangxi Province

赣南钨成矿区地处南岭成矿带中东段,分诸广山东坡、于山、武夷山3个区域构造单元。震旦寒武系为钨矿源层,燕山期成矿花岗岩的侵入演化是钨成矿定位的首要地质条件,与成矿围岩构造多样性耦合,一体多位、一体多型、一体多矿成矿。赣南进入拓深找矿阶段,通过老点新评、老区新探、新区探矿,再探100万t钨矿。-

The tungsten metallogenic district of South Jiangxi Province situates in the mid-east part of the Nanling EW metallogenic belt. It subdivides into three regional tectonic areas, i.e., east Zhuguangshan, Yushan and Wuyishan. The Simian and Cambrian strata in the area are regarded to be the sources of W element. The Yanshanian metallogenic granitoid is the leading geological factor in the mineralization progress of tungsten, added by strata and the structures. It results in the metallogenic features of ＂muhi-ores, multi-types and multi-deposits in one-body＂. The targets of the geological exploration are aimed at the deeper parts of the area. 10 000 thousands tons of WO3 may be found through the renew-geological exploration of the old ore-points, the renew-geological exploration of the old areas and the geological exploration of the new areas.
