最近几年昆阳磷矿二采区(17~#—28~#半剖面线之间)进行了生产加密勘探。笔者一直在该区从事矿山地质工作。现就该矿段磷块岩矿床的某些地质特征,提出几点肤浅的认识: 一、矿体赋存层位及 含磷岩系特征 下寒武统为主要含磷岩系。共发育了五层磷块岩,其中目前开采的中谊村段上下两层磷块岩,质优量大,构成“昆阳式”磷块岩工业矿床,而闻名中外。 现将五层含磷岩系特征由新到老分别简介如下:
In recent years, the second mining area of Kunyang Phosphate Mine (17 ~ # -28 ~ # half-section line between) conducted production-intensive exploration. I have been engaged in mine geological work in the area. Now some of the geological characteristics of the phosphate rock block of the mine, put forward some superficial understanding: First, the ore-bearing strata and phosphorus rock characteristics of the Lower Cambrian as the main phosphorus-bearing rock series. A total of five layers of phosphate rock were developed. Among them, the upper and lower two layers of phosphate rock currently being mined in Zhongyi Village are of high quality and good quality and constitute the “Kunyang-style” phosphorite industrial deposit, which is famous both at home and abroad. Now five layers of phosphorus rock characteristics from new to old are as follows:
