A medium - sized manganese ore is found in Tongling, Guangxi
A medium - sized manganese ore is found in Tongling, Guangxi By the Guangxi fourth geological team to bear the Yizhou area and Xincheng area 1: 50000 scale geological and mineral survey 2 projects, through the work, the current stage results. Which in the Mazi mining area of manganese oxide ore body 5, manganese carbonate layer 4, the initial estimate of manganese carbonate ore 11.1 million tons, up to medium-sized.
It is understood that the project team completed a total of 3784 square meters of geological mapping, remote sensing geological interpretation of 3800 square kilometers, field observation section of more than 60 total length of 393.2 km, nearly 3,000 samples of rock samples, water sediment measurements 234 square thousand Rice, soil measurement 1660 square kilometers, trench exploration 6400 cubic meters, the basic chemical analysis of 900 rock samples, spectral analysis of geochemical exploration of 8200 pieces. At present, these two projects have achieved initial results.
First, the comprehensive study of the stratigraphic space distribution, lithology assemblage, paleontological facies, lithofacies palaeogeography, sequence characteristics, etc., confirmed that the Yizhou area, especially the Xincheng area since the Falls (385Ma) by the North North East And the northwest to the regional impact of the formation of the formation of ditch, Taiwan phase pattern; to Nan Dan group of gray thin layer of sandy lumps, strip limestone as the boundary will be Miao - Tongling - Fulong area divided into a North The sedimentary facies of the basin in the northeastern trending basin is confirmed, and the distribution of the Lower Carboniferous Baoping Formation and its rock composition is confirmed, and the depth of the basin is measured. Second, the system of investigation and focus on anatomy, the initial identification of folds, the type of fault, evolution and other characteristics, initially that the Miao - Tongling - Fulong area north - north tectonic structure of the early formation of limestone rock breccia Filled with calcite, the middle of the original fracture along the crushed surface to form crushed rock, lacustrine limestone, later by the North West to the tectonic transformation, the overall control of Miao - Tongling - Fulong basin spatial distribution and basin uplift, the formation The edge of the platform is characterized by significant correlation between controlling the rock and controlled rock formation in the structure and structure of the carbonate - Improve the degree of research on the structure of the survey area. Third, in the area of Tongling, with the lithology of the lithology, stratigraphy and lithology construction of the three elements as the manganese ore exploration theory guidance, the Ma Si mining area to complete the main physical workload drilling 2000 meters, trough 3500 cubic meters, access to manganese oxide ore body 5 , Manganese carbonate layer 4, the initial estimate of manganese carbonate ore 11.1 million tons, up to medium-sized. Manganese ore exploration was a major breakthrough. The results show that the source of manganese material may be mainly composed of hydrothermal and improve the origin of manganese ore. The results show that the source of manganese material is mainly composed of hydrothermal sediment, and the source of trenches and basins is relatively closed. understanding. Five is the basic identification of the Upper Carboniferous Tai Po Formation (rock) spatial distribution and mineral content, is expected to submit dolomite exploration base 2. The results show that there are 11 geochemical data of Au, Cu, Pb, Zn, Ag, Sn, Mo, Mn, As, Sb and P, and the comprehensive anomaly is 32, Ore 2, tin-lead multi-metal 1.
About CHINA MINING
Since first held in 1999, the scope and influence of CHINA MINING has grown rapidly year by year. As a global mining summit forum and exhibition, CHINA MINING Congress and Expo has become one of the world’s top mining events, and one of the world’s largest mining exploration, development and trading platforms, covering all aspects of the whole mining industry chain, including geological survey, exploration and development, mining rights trading, mining investment and financing, smelting and processing, mining techniques and equipment, mining services, etc. playing an active promotion role in creating exchange opportunities and enhancing mutual cooperation between domestic and foreign mining enterprises.
CHINA MINING Congress and Expo 2017 will be held at Meijiang Convention and Exhibition Center in Tianjin in September 23-25, 2017. We invite you to join the event and to celebrate the 19th anniversary of CHINA MINING with us. For more information about CHINA MINING 2017, please visit: m.balanzskin.com.
