赣南是世界著名的脉状钨矿产地,许多地学工作者对其作过详细研究。本文在前人工作的基础上,拟对脉状钨矿的某些地球化学特征及分布规律作进一步探讨。一、地质简况赣南位于南岭山系东段(图1)。泥盆纪以前,这里地壳大幅度下陷,沉积了巨厚的复理石建造、碎屑岩建造、碳酸盐建造及火山岩建造。区内震旦系、寒武系、奥陶系广泛分布。下古生代末期的强烈地壳运动,使泥盆纪以前的地层普遍上升褶皱,并伴有大规模酸性
Gannan is a world famous vein tungsten ore, many geoscientists made a detailed study of it. Based on the previous work, this paper intends to further investigate some geochemical characteristics and distribution of the vein-type tungsten ore. First, the geological profile Gannan is located in the eastern section of the Nanling Mountains (Figure 1). Before the Devonian, the crust was subsided here drastically, with massive thick flysch, clastic rock formation, carbonate formation and volcanic rock formation. Sinian, Cambrian, Ordovician widely distributed. The strong crustal movement at the bottom of the Paleozoic resulted in the general increase of folds in the Devonian strata and the accompanying large-scale acidity
