Nickel-metal deposits have been systematically surveyed for more than half a century, and the difficulty of prospecting has increased. Recently, the Ministry of Land and Resources, Key Laboratory of Magmatic Ore-forming and Prospecting, in view of the particularity of the magmatic copper-nickel sulphide deposit, broke through the previous model of metallogenic belt evaluation, and carried out the prospecting potential and prospect evaluation for the first time.
It is understood that the laboratory has clarified the metallogenic characteristics of China's magmatic copper-nickel sulphide deposits, and deeply explored the deep-sedimentation pre-enrichment of small-scale rock masses into large-scale ore-forming mineralization theory, which is compared with the world's important similar ore-concentrating areas. The metallogenic potential and prospecting potential of China's magmatic copper-nickel sulfide deposits are proposed. Select the northeastern margin of Tarim Craton, the Qilian-Longshou Mountain and the Qaidam Craton Perimeter, the northern margin of the North China Craton and the western margin of the Yangtze Craton and the concentrated distribution area of ​​the copper-nickel ore. Analyze regional geological, mineral, geochemical, remote sensing and other prospecting information, use petrology and geochemical methods to explore its magma formation and evolution and deep geological processes, determine ore-controlling factors and prospecting indicators, and determine its ore-bearing properties. In the research process, highlighting the field needs of prospecting practice, focusing on the key scientific issues that constrain the prospecting breakthrough, and integrating with the production of first-line scientific and technological personnel, to achieve a win-win situation in the theory of mineralization innovation and the practice of prospecting breakthrough. Explore the establishment of new metallogenic and ore-seeking models, and provide practice and demonstration for mineralization and prospecting of other minerals and metallogenic types.
