| 中文摘要:我国钨矿床类型主要有斑岩型钨矿、矽卡岩型钨矿、云英岩型钨矿、石英脉型钨矿、蚀变花岗岩型钨矿、砂钨矿和其它类型钨矿。其中，矽卡岩型钨矿和石英脉型钨矿是主要矿床类型。本文编制了中国钨矿空间分布及开发利用现状图，共划分出13个成钨区带。我国钨矿具有广泛展布且局部集中的特点，大中型矿区及白钨矿矿石类型资源储量占主导。我国钨矿床共（伴）生组分多、综合利用价值大，但富矿少、贫矿多。钨矿是我国优势的矿产资源，我国是世界上最大的钨生产国和供应国，钨年产量占世界年产量的81%。我国钨产业链覆盖完整，前端和中端具有明显优势，高性能、高精度的高档硬质合金仍依赖国外进口。 |

| Abstract:The tungsten deposits can be classified into 7 major types: porphyry-, skarn-, greisen-, quartz vein-, altered granite-type tungsten deposit, sand tungsten deposit and other type of tungsten deposit in China. The skarn- and quartz vein-type tungsten deposits are dominated in China among these types of tungsten deposits. The spatial distribution, development and utilization of tungsten deposits in China are compiled in the paper. Tungsten deposits are divided into 13 metallogenic belts (regions). Tungsten ore in China is characterized by wide distribution and local concentration. Tungsten resources and reserves are dominated by large- and medium-sized orefields and scheelite ores. There are many paragenetic and associated components in tungsten deposits with the comprehensive great utilization value in China. There are little rich tungsten ores, many poor tungsten ores. Tungsten deposits are the dominant mineral resources in China. China is the most significant producer and exporter of tungsten in the world. China's annual output of tungsten accounts for 81% of the world's annual output. Tungsten industry chain is integrated in China. The front end and the middle end of China tungsten industry chain have obvious advantages in the world. At the same time, the high-quality hard alloy with high performance and high precision relies on imports. |
