项目摘要

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

中国地质省由西伯利亚板块、塔里木华北板块、中央造山带、华南板块、青藏云南板块和印度板块组成。目前我们对世界上任何一个国家开采新的矿产资源都非常悲观。但需要强调的是，在全国范围内，只有中国是开发大量矿藏的富有成效的国家。 1993年以来，我国已发现和开发矿产地约70处。这些矿产地几乎全部分布在我国中南部，即中央造山带、华南板块、藏滇板块等地区。该区域正是本研究的目标、领域。从新发现的矿床中提取的矿产商品的主要元素主要是铜、铅、锌、金、银、锡和钨。此外，还有少量矿藏，主要产锰、铁和铀。一些矿床在选矿过程中会提取稀土元素 (RE)、镍、钼、金、银和锑等副产品。铜矿床分为超大型（以铜产量1Mt以上为特征）、大型（1Mt至50万吨）、中型（50万至5万吨）和小型（5万吨以下）。新发现的超大型、大型矿床大多分布在目前勘察领域。铜产量矿产资源评估显示，超大型矿床超过1Mt，大型矿床超过2.81Mt，中型矿床超过0.55Mt，小型矿床超过0.0012Mt。新发现的铅、锌矿床仅分布在华南板块，共编号为6个矿床。所有矿床中的 5 个矿床被归类为生产 1 至 5 吨铅和锌的大型矿床。通过矿产资源评估预计铅、锌产量超过1.7Mt。 10年来新发现金银矿床30处。矿床几乎全部分布在华南板块。金、银资源评估估计，黄金资源量超过305吨，白银资源量超过6300吨。新发现的锡、钨矿床也分布在华南板块，经评估超过90万吨。较少的
