叠生成矿作用在赣北是一种最重要的成矿作用,塔前-朱溪多金属成矿带就是一例.该成矿带位于景德镇与乐平县的交界处,呈北东向延展达35公里以上.带内有关的多金属矿床,既受中石炭统黄龙组、下二迭统茅口组层位控制,又受中生代地洼阶段中酸性斑岩类叠生成矿作用的制约,几乎每个矿床都具有叠加式层控矿床的特征. 成矿带地质构造特征成矿带的基底由前震旦纪变质岩系组成.盖层主要为上古生界地层,其中的中石炭统黄龙组
The stratigraphic mineralization is one of the most important metallogeny in northern Jiangxi, an example is the Tazian-Zhuxi polymetallic metallogenic belt, which is located at the junction of Jingdezhen and Leping County, extending north-eastward to 35 Km above the belt.The relevant polymetallic deposits in the belt are controlled not only by the Huanglong Formation of the Carboniferous and the Maokou Formation of the Lower Permian but also by the superimposed mineralization of the acidic porphyry in the Diwa stage of the Mesozoic. Each deposit has the characteristics of superimposed stratabound ore deposit.The geological structure of the metallogenic belt The basement of the metallogenic belt is composed of pre-Sinian metamorphic rocks, and the caprock is mainly Upper Paleozoic strata, of which the Carboniferous Huanglong Formation
