云南镍钴矿成矿规律及找矿方向
Metallogenic Regularity and Prospecting Direction of Nickel and Cobalt Deposits in Yunnan Province
摘要
Abstract
Nickel and Cobalt are critical strategic minerals in short supply in China.Ensuring their availability is of utmost importance for national stability and development.As the hotspot for non-ferrous metals,Yunnan Province has 42 nickel deposits and 48 cobalt deposits,and these identified resources are in the forefront of the country,with good nickel and cobalt prospecting potential.Based on previous research,this study reviews the genetic types,temporal and spatial distribution,and mineralization of nickel and cobalt deposits in Yunnan Province,summarizes the metallogenic regularity,and discusses the prospecting direction.Nickel and cobalt deposits in Yunnan Province can be divided into 6 types:magmatic type,magmatic hydrothermal type,Marine volcanic type,metamorphic type,medium-low temperature hydrothermal type and weathering type.Nickel and cobalt deposits are mainly concentrated in the Yangtze landmass and Sanjiang orogenic belt,nickel deposits are mainly formed in the Indosinian and Himalayan ages,cobalt deposits are mainly formed in the Himalayan,Jinning and Indosinian ages.The magmatic and weathering nickel and cobalt deposits are closely related to the basic-ultrabasic rock intrusion activities of the Indosinian Yangtze landmass.The medium-low temperature hydrothermal cobalt deposits are related to the tectonic activities in the Sanjiang orogenic belt formed by the Himalayan orogenic activities.The marine volcanic type and sedimentary metamorphic type cobalt deposits are located in the Kunyang Group and Dahongshan Group in the Yangtze landmass,which are related to the volcanic activities of the Jingning Age.Based on the analysis and summary of mineralization rules of nickel and cobalt deposits in the province,combined with the results of potential evaluation,a total of 8 prospecting potential areas are delineated in this paper.Therefore,this study provides insights for the exploration and deployment of nickel and cobalt ore in a new round of prospecting breakthrough strategic action in Yunnan Province.关键词
