First total amount estimation of the key mineral resources within 2000m under the earth surface accomplished in China
From the review and acceptance conference for national key mineral resource total amount estimation on December 30, 2013, reporters obtained the newest information about the mineral resource potential assessment project. After 8-year efforts, China has accomplished estimation of the total amount of 23 key minerals within 2000m under the earth surface including iron, aluminum, copper, lead and zinc, which is of great significance for mineral prospection and exploration and state resource strategies.
According to academicians and experts Zhao Dapeng, Chen Yuchuan, Zhai Yusheng, Pei Yongfu, Zhang Hongtao and Zhong ziran, the project set up a mineral resource estimating system based on deposit model comprehensive geological information. Tectonic mapping based on plate tectonics and metallogenic dynamics provided a solid foundation for mineralization environment prognosis. Deposit comprehensive information prospecting model was established on the basis of mineral prognosis categories of metallogenic series. Directed by comprehensive information mineral resource quantitative prognosis method, target regions (minimum regions for prognosis) delineation and unfound resource estimation were conducted and first-hand statistics were collected.
Directed by the above estimating system, the project delineated 50,000 prospecting targets and metallogenic prospects of different levels, from which provincial metallogenic prospects and national ones were selected. The potential resources in each target and prospect were estimated and evaluated. The distribution diagram of each mineral and its prospect was compiled, as well as the prospection diagram. The statistics have been widely applied to national and provincial mineral resource planning, strategies for mineral prospecting breakthrough and mining management, etc. (Yu Defu) (Translated by TLRHVC)
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 2014 will be held at Meijiang Convention and Exhibition Center in Tianjin on October 20-23, 2014. We invite you to join the event and to celebrate the 16th anniversary of CHINA MINING with us. For more information about CHINA MINING 2014, please visit: www.chinaminingtj.org.
