最近,我们在浙西淳安县姜家公社附近出露的上震旦统西峰寺组内,发现了三个主要含磷层。自下而上分别称为第Ⅰ、Ⅱ、Ⅲ含磷层。其厚度分别为4米、5米和2.3米。三个含磷层集中在60.8米厚的范围内。这个剖面的岩石组合与常山县西门外西峰寺标准剖面很不相同,故对研究浙西晚震旦世古地理环境和指导找矿,都是有意义的。 Recently, we found three major phosphorous layers in the Upper Sinian Xifengsi Formation exposed near Jiangjia Commune in Chun’an County, western Zhejiang Province. Bottom-up are called Ⅰ, Ⅱ, Ⅲ phosphorus layer. Its thickness is 4 meters, 5 meters and 2.3 meters respectively. The three phosphorous layers are concentrated in the range of 60.8 meters thick. The rock assemblage in this section is very different from the standard section of Xifeng Temple outside the west gate of Changshan County. Therefore, it is meaningful to study the late Sinian paleogeographic environment and ore prospecting in western Zhejiang.
