| 摘 要： | 赣中变质岩带在空间上具递增变质带分布特征,根据随变质作用增强而出现的新变质矿物及矿物组合划分出绢云母绿泥石带、黑云母带、铁铝石带、十字石带、矽线石带,部分地段还出现混合岩带。矽线石发育于矽线石带的含榴矽线云母片岩、含矽线斜长变粒岩中,化学成分与其寄主岩石的化学成分、成物成分有一定的关系,富含Al、K和云母的含榴矽线云母片岩,其中的矽线石中Al含量相对高,K含量很低。而富含Si、Ca、Na、K和斜长石,贫Al和云母的含矽线斜长变粒岩,其中的矽线石中Al、Na含量相对稍低,K含量稍高。

| Abstract: | With the increase of metamorphic degree and appearance of typical metamorphic mineral from south to north, the metamorphic rocks belt in central Jiangxi province can be subdivided into five metamorphic zones : sericite-chlorite zone, biotite zone, almandite zone, staurolite zone and silicon zone. In this paper, the chemical composition characteristics and occurrence of silicon are preliminarily studied, and its genesis being investigated . |
