| 摘 要： | 前进场岩体在岩石地球化学方面以过铝、富集ＬＲＥＥ、具中等负Ｅｕ异常为特征，∑ＲＥＥ介于１０７．８１－１４３．２４μｇ／ｇ之间，结合其野外地质特征和区域构造分析，本文认为该岩体为板块碰撞期间于晚石炭世由沉积物质部分熔融而形成的Ｓ型花岗岩。

| Abstract: | The Qianjinchang batholith is characterized geochemically by Peralumin-ous nature,enrichmoent in LREE and possession of a medium negativc Eu anomaly,It contains a lot of xenoliths of sedimentary rocks ard its emplaec-ment resulted in very wide aureole in the host rocks.These characteristics combined with regional tectonic analysis demonstrate that the batholith was formed by partial melting of sedimonts during the collison stage in Late Carboniferous. |
