Fundamental study of characteristics of mineral distribution and mineral resource assessment in the Southeastern part of China

中国地质省由西伯利亚板块、塔里木-北中国板块、中央造山带、南中国板块、藏滇板块和印度板块组成。目前，我们非常悲观地认为，世界上任何一个国家都不可能获得新的矿产资源。但需要强调的是，只有中国才是全国范围内开发大量矿藏的丰硕国度。自1993年以来，中国已发现和开发了近70个矿床。这些矿床几乎都分布在中国的中南部，即中央造山带、中国板块南部、藏滇板块。这一区域正是本文研究的对象、领域。从新发现的矿床中提取的矿物商品的主要元素主要是铜、铅、锌、金、银、锡和钨。此外，少量矿藏主要生产锰、铁和铀。形成了一些矿藏，副产品如Rare-…在选矿过程中，提取了更多的稀土元素(RE)、镍、钼、金、银和锑。铜矿床可分为超大型铜矿床，其特征是铜产量在1百万吨以上，大型在1百万~50万吨之间，中型在50万~5万吨之间，小型在5万吨以下。新发现的特大型、特大型矿床主要分布在本探区。铜生产矿产资源评价表明，超大型铜矿床确定的铜矿产量超过1Mt，大型铜矿床超过2.81Mt，中型铜矿床超过0.55Mt，小型铜矿床超过0.0012Mt。新发现的铅锌矿床仅分布在中国板块南部，共6个矿床。所有矿床中的5个矿床被归类为产铅、锌1~5Mt的大型矿床。通过矿产资源评价，预计铅锌产量在170万吨以上。近10年来又新发现了30个金银矿床。几乎所有的矿床都分布在南中国板块。金和银的资源评估估计，黄金超过305吨，白银超过6300吨。新发现的锡钨矿床也分布在南中国板块，估计超过90万t。较少

The geologic province in China consists of Siberia plate, Tarim-North China plate, Central Orogenic belt, South China plate, Tibet-Yunnan plate, and Indian plate. In the present we are very pessimistic to take new mineral resources in any country in the world. However, it is emphasized that only China is fruitful country developing a lot of mineral deposits within the nation. Approximate 70 mineral deposits have been discovered and developed in China since 1993. Almost all of these mineral deposits distribute in the Central to Southern part of China, that is, in Central Orogenic belt, South China plate, Tibet-Yunnan plate. This region was just the target, field of the present study. The major elements extracted for mineral commodities from the newly discovered deposits are principally copper, lead, zinc, gold, silver, tin, and tungsten. In addition, small amounts of mineral deposits produce mainly manganese, iron and uranium. Form some of mineral deposits, the by-products such as rare- … More earth elements(RE), nickel, molybdenum, gold, silver, and antimony are extracted during the mineral processing. The copper ore deposits are categorized into the Super Large size characterized by the Cu production above 1Mt, Large size by 1Mt to 500,000t, Medium size by 500,000 to 50,000t, and Small size below 50,000t. The Super Large and Large size mineral deposits discovered newly distribute mostly in the present examined field. The mineral resource assessment of Cu production reveals that more than 1Mt are determined from the Super Large size deposits, more than 2.81Mt from the Large size deposits, more than 0.55Mt from the Medium size deposits and more than 0.0012Mt from the Small size deposits. The newly discovered Pb and Zn deposits distribute only in the South China plate and are numbered totally 6 ore deposits. The 5 deposits of the all deposits are categorized into the Large size deposits producing the lead and zinc of 1 to 5Mt. The estimated Pb and Zinc production through the mineral resource assessment is more than 1.7Mt. The 30 gold and silver deposits have been discovered newly for these 10 years. Almost all deposits distribute in the South China plate. The resource assessment of Au and Ag estimates more than 305t for gold and more than 6,300t for silver. Tin and tungsten deposits discovered newly also distribute in the South China plate, being assessed that more than 900,000t. Less
