摘要
豫西南地区是中国中部重要的多金属成矿远景区。对区内成矿地质条件和典型矿床特征进行了总结,认为①与官道口群碳酸盐岩和栾川群碎屑岩-碳酸盐岩沉积建造有关的层状铅锌银矿床、②与燕山期花岗(斑)岩有关的铅锌银(铜)矿床、③与古生界海相火山-碎屑岩建造有关的锌铜(铅、银、金)矿床是今后调查的3种主要矿床类型,并圈定出12处找矿远景较好的矿集区(矿化集中区)为重点工作地区,为下一步找矿勘查工作部署提供了依据。
The southwestern Henan Province, central China, is an important polymetallic ore prospect area. According to the metallogenic geological conditions and typical features of the deposits in the area, three major types of deposit are summarized as follows: ① stratiform lead-zinc-silver deposits related to the Guandaokou Group carbonate rocks and Luanchuan Group clastic-carbonate rocks; ② lead-zinc-silver (copper) deposits related to Yanshanian granite (porphyry); and ③ zinc-copper (lead-silver-gold) deposits related to Paleozoic marine pyroclastic rocks. The three major types of deposit are those that will be surveyed in the future. In addition, 12 ore deposit (mineralization) concentration areas with good ore prospects have been outlined, which will provide a basis for future ore prospecting.
