九曲湾砂岩铜矿位于江南地轴西南缘,为一套中新生代山间坳陷盆地沉积.矿区出露白垩系,由紫红色泥质粉砂岩、粉砂岩、粉砂质泥岩、泥岩及细砂岩(深色层)与灰紫-灰绿-灰白-浅灰色含砾中、粗砂岩和细砂岩(浅色层)互层组成.深色层多为厚层状,浅色层多为薄层状.两色岩层组成含矿岩系,平均厚567米,自南而北急剧变薄. 矿体呈层状、似层状、透镜状或扁豆状赋存于浅色层中.在百余条浅色层中,已发现矿体近40条,空间上呈北北东向展布,边幕式排列(图1).
Located on the southwestern margin of the axis of Jiangnan, the Jiuquwan Bay sandstone copper deposit is a set of Mesozoic-Cenozoic mountain depression basin deposits exposed by the Cretaceous, consisting of purple-red muddy siltstone, siltstone, silty mudstone, mudstone and fine Sandstone (dark layer) and gray purple - gray-green - gray - light gray pebbles, coarse sandstone and fine sandstone (light-colored layer) interbedded layer.Dark layer is mostly thick layer, light layer mostly thin Layered two-color rock composition of ore-bearing rock series, an average of 567 meters thick, sharp thinning from south to north.The ore body is layered, like layered, lenticular or lenticular occurrence in the light-colored layer. In the remaining light-colored layers, nearly 40 ore bodies have been found, exhibiting a north-north eastward spatial distribution and a curtain arrangement (Figure 1).
