| 摘 要： | 四川省雷波县瓦岗磷矿位于川西南磷矿矿集区的南部,矿体赋存于下寒武统麦地坪组第二段,呈层状展布于瓦尼觉背斜两翼,含矿建造为硅质岩-碳酸岩-磷块岩,矿石结构构造为球状、团块状、条带状,文章通过对矿石和围岩地质特征研究,认为矿床形成于海湾潮下低能带的古地理环境,成因主要为富磷生物碎屑沉积聚集而成。

| Abstract: | The phosphate deposit is located in the southern part of phosphorus ore deposit-clustered area in the west Sichuan province. Ore bodies occur in 2nd member of Lower Cambrian Maidiping formation as layers at two limbs of Waijue anticline. Siliceous rock-carbonate rock-phosphate rock is the ore-bearing formation. The ore is in spherical, clumps, banded structure. We studied geological characteristics of the country rock and considered that the deposit is formed under subtidal low energy zone environment by accumulation phosphorus-rich biofragments. |
