摘要
贵州遵义-水城地区二叠纪锰矿已先后发现锰矿床(点) 29个,累计提交锰矿资源储量达1. 76亿吨,所有锰矿床均位于黔北裂谷盆地分布范围内,据其特征可分为"遵义式"锰矿和"水城式"锰矿,典型矿床分别为铜锣井-深溪锰矿床和徐家寨锰矿床。结合锰矿成矿地质背景,本文将贵州遵义-水城地区二叠纪锰矿成矿带划分为遵义-黔西、水城-宣威2个锰矿成矿亚带、5个矿带和18个锰矿预测区。通过总结提取贵州二叠纪锰矿"古天然气渗漏沉积型锰矿床预测要素",根据预测要素、成矿规律开展找矿潜力分析,预测遵义-水城二叠纪锰矿成矿带资源潜力2. 45亿吨,找矿潜力巨大。
29 manganese deposits(sites)has been found in the Zunyi-Shuicheng Permian Manganese Deposit of Guizhou Province with proven reserves of 176 million tons.All the manganese deposits are located in the northern Guizhou rift basin.According to their features,they are divided into“Zunyi”manganese deposit and“Shuicheng”manganese deposit,the typical deposits are Tongluojing-Shenxi manganese deposit and Xujiazhai manganese deposit.In this paper,the Permian manganese deposits in Guizhou are divided into Zunyi-Qianxi and Shuicheng-Xuanwei manganese metallogenic belts and 7 small metallogenic belts and 13 manganese ore prediction area.The“predictive elements of ancient natural gas seepage sedimentary manganese deposits”of the Permian manganese deposits in Guizhou are summarized and extracted,according to the predictive factors and metallogenic rules,the prospecting potential is analyzed and the Permian manganese ore resources in Zunyi and Shuicheng,the source potential is 2.68 billion tons and the prospecting potential is huge.
