摘要
岩石空间产出特征、岩相学、岩石化学、稀土元素地球化学特征及成岩成矿作用特征等分析研究表明,硅质钠长石岩是经沉积变质、硅质钠质交代作用形成的,原岩组成多样,主要为碳质板岩,其次为条带状泥砂质白云岩,局部也可以是辉绿辉长岩。
The analysis and study of the spatial occurrence characteristics of the siliceous albite rock, petrofabrics, petrochemistry, REE geochemistry and diagenetic-minerogenetic characteristics indicated that the siliceous albite rock was formed through the sedimentary-metamorphism,siliceous-sodic metasomatism. Their primary rock assemblage is various,and composed mainly of carbonaceous slate,then minor striped mud-sand dolomite,and may be some diabase-gabbro locally.
