【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。更多还原

【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 2 nd 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.更多还原
