摘要
在峡江县马埠地区进行1:5万峡江县幅区调工作中,在原石溪组之下发现一套岩性底部为灰白色石英质砾岩与灰白色含砾石英砂岩互层,下部为猪肝、土黄、青灰色粉砂岩、含粉砂质泥岩、含碳质泥岩,间夹少量薄层细砂岩,发育平行层理,中部为浅灰色石英质砾岩与灰色粗中粒长石岩屑砂岩互层,上部为紫红色含角砾流纹质弱熔结凝灰岩组合的地层,并采获植物化石Manica。其时代属早白垩世。其岩石地层单位划归石溪组下部。
The new plant fossil Manica belonging to early Cretaceous is found in low part of Shixi formation during geological survey of 1:50000 Xiajiang map. The lithology of hosting fossil is charaterized by grey white with quartz psephyte interbeded quartz sandstone in the bottom, green grey siltstone siltpelite?carbargillite mud in the low part, grey quartz psephyte and feldspar sandstone in the middle part, weak welded purple tuff in the upper part. The stratitgraphy of the rock is classified into low part of Shixi formation.
