| 摘 要： | 厂坝铅锌矿床中钠长石岩的产状、常量元素、微量元素、稀土元素和放射性同位素等地质地球化学特征表明．该岩石为中泥盆统成矿流体在海底沉积和交代围岩形成的典型热液沉积岩——钠长石岩，其物质来自矿体的下状沉积地层柱和海水。该沉积岩在后期的强烈变质改造过程中，发生了重结晶作用。

| Abstract: | The albitites discussed in this paper are located in the lower part and at the bottom of orebody No.2 in the Changba Pb-Zn ore dePosit. Their geological and geochemical characteristics such as occurrence, Major elements, trace elements, rare-earth element composition and radioactive isotopic composition indicate that the rocks are typical submarine hydrothermal sediments deposited by ore-bearing fluids. The material came from underlying sediments and sea water. During the Yenshanian Movement, the rocks underwent strong metamorphic re formation and complete recrystallization. |
