一、含矿岩系特点本矿床位于江南古陆东侧,吴兴-昌化加里东期隆起区南缘,北东与北北东向断裂交汇处的中生代晚侏罗世寿昌期断陷盆地中。上与白垩纪红层,下与晚侏罗世火山岩,均呈不整合接触(图1)。其含矿岩系属侏罗系上统寿昌组,在矿区内的分布面积约11平方公里,西北和东南侧分别与晚侏罗世火山岩和早古生代碳酸盐岩呈断层接触(图2)。寿昌组沉积中心在竹林桥附近,总
Characteristics of ore-bearing rock series The deposit is located in the Shouchang faulted basin in the Mesozoic and Late Jurassic to the east of Jiangnan ancient land, the Wuxing-Chang’an Caledonian uplift south margin and the NE-NE-EHR intersection. Upper and Cretaceous red beds, and Late Jurassic volcanic rocks, showed unconformity contact (Figure 1). The ore-bearing rocks belong to the Jurassic Upper Shouchang Formation and have a distribution area of about 11 km 2 in the mining area. In the northwest and southeast, they are in fault contact with Late Jurassic volcanic rocks and Early Paleozoic carbonates (Fig. 2 ). Shouchang Deposition Center near the bamboo bridge, the total
