| 摘 要： | 通过对相山铀矿田钻孔资料、地球物理资料的综合研究,笔者编制了相山火山盆地火山岩组间界面、基底界面等高线图,初步查明了组间界面、基底界面形态特征和埋藏深度,认为火山岩组间界面变异部位为上部铀矿的重要赋矿空间（第1成矿空间）;基底界面控制着晚期花岗斑岩,也控制着下部铀矿的空间定位（第2成矿空间）.组间界面（变异部位）、基底界面与断裂构造复合处,为铀矿最有利的赋存部位.

| Abstract: | By means of the integrated study of boreholes and geophysical data, contour maps of inter- faces between volcanic formations and of basement have been compiled for Xiangshan volcanic basin. The morphological characteristics of interfaces and its buried depth have been preliminarily identified. Thetransformed parts of interfaces between volcanic formations are regarded as the upper ore- hosting space （called the first ore - forming space）, while the interfaces of basement which controll both younger gra- nitic porphyry and the lower uranium mineralizing space （called the second ore- forming space）. The best ore- forming area is located in the faults compounded with interfaces between volcanic formations and covers to basement. |
