摘要
通过对遵义地区关土、黄层顶、五里堡、大坡、三岔等典型矿床地质特征进行分析,研究该地区水泥用灰岩矿床的成矿规律.结果表明:遵义地区的水泥用灰岩矿属于沉积型灰岩矿床,矿体呈层状,与岩层产状一致,矿石总体质量稳定;夜郎组是该区最重要的一个赋矿层位,具有厚度大、质量好、找矿前景好的特点,经济价值较高;茅口组下灰岩段矿石质量最优,找矿前景好;关岭组灰岩段厚度较大,质量一般;嘉陵江组赋矿层位矿体厚度一般,质量较好,但受岩溶发育和顶板岩性影响,不利于矿石开采,找矿前景较差.
Abstract
By analyzing the geological characteristics of typical deposits such as Guantu,Huangceng-ding,Wulipu,Dapo and Sancha in Zunyi area,the metallogenic regularity of cement limestone deposits in this area is studied.The results show that the cement limestone deposits in Zunyi area belong to sedimentary limestone deposits.The ore bodies are layered,consistent with the occurrence of rock strata,and the overall quality of the ore is stable.The Yelang Formation is the most important ore-bearing stratum in this area.It has the characteristics of large thickness,good quality and good prospecting prospect,and has high econom-ic value.The ore quality of the lower limestone section of Maokou Formation is the best and the prospecting prospect is good.The thickness of the limestone section of the Guanling Formation is large and the quality is general.The thickness of ore body in the ore-bearing layer of the Jialingjiang Formation is general and the quality is good.However,due to the influence of karst development and roof lithology,it is not conducive to ore mining and the prospecting prospect is poor.
