广西忻城县里苗-塘岭锰矿床控矿因素及成矿模式
|
摘要
广西宜州市龙头锰矿是我国石炭系锰矿的典型代表。2014～2016年,中国冶金地质总局广西地质勘查院在南丹-宜州地区开展矿产地质调查工作取得了新的突破,圈定了弄竹、塘岭找矿靶区。两个靶区经后续广西地勘资金勘查,在里苗-塘岭一带估算锰矿资源量达8000多万吨,成为我国石炭系最大的锰矿。为了揭示该矿床的成矿机制,本文从区域成矿地质背景、矿床地质特征、构造环境、岩相古地理、锰质来源、矿化富集规律等方面分析了其控矿因素,圈定了成锰盆地边界线,建立了成矿模式。认为里苗-塘岭锰矿床是受NE向同沉积断裂控制的海底热水沉积矿床,是走滑拉张断陷-含锰热水-台沟相沉积环境耦合作用的产物。
The Longtou manganese deposit is one of the typical Carboniferous manganese deposits in China. During 2014-2016,the Guangxi Geological Exploration Institute of China Metallugical Geology Bureau has made a new breakthrough of mineral prospecting in the Nandan-Yizhou area,and has delineated two ore-prospecting targets of the Nongzhu area and Tangling area. In the follow-up fund exploration of Guangxi Geological Prospecting Bureau,the amount of manganese ores estimated in the Limiao-Tangling area reached more than 80 million tons,and then became the largest Carboniferous manganese deposit in China. The metallogenic mechanism of the deposit is revealed in charge of the analysis on multiple geological studies,such as regional metallogenic geological setting,mineralogical characteristics,tectonic environment,lithofacies palaeogeography,manganese source and the regularity of mineralization enrichment. Furthermore,based on the analysis of the ore-controlling factors mentioned above,the boundary of manganese basin is delineated,and the metallogenic model is established. It is considered in this paper that the Limiao-Tangling manganese deposit is a submarine hydrothermal sedimentary deposit controlled by NE-trending synsedimentary faults,as well as the coupling interactions of strike-slip extensional depression,manganese-bearing hydrothermal water and platform-trench facies sedimentary environment.
