河南西峡县洋淇沟橄榄岩矿床地质特征及开发利用

Geological characteristics and development utilization of Yangqigou peridotite deposit in Xixia County,Henan Province

河南省西峡县洋淇沟橄榄岩矿床位于河南省西峡县西坪镇洋淇沟的西北部,赋存于中—新元古界峡河岩群界牌岩组松树沟—洋淇沟岩体中,本文介绍了洋淇沟橄榄岩岩体的地质背景及岩相构造特征、形态产状、岩石类型、化学成分、形成时代及成因等,分析了矿石加工技术性能及产品应用,认为洋淇沟橄榄岩矿床出露地表,易于开采,橄榄岩可用于耐火材料、铸造行业、农用肥料、建筑行业、工程陶瓷、工艺品、酸化橄榄岩浸取镁等行业,通过对洋淇沟橄榄岩矿床的进一步研究,为合理开发利用洋淇沟橄榄岩矿产资源提供地质依据。

The Yangqigou peridotite deposit,is located in the northwest Yangqigou,Xiping Town of Xixia County,Henan Province.It occurs in the Songshugou-Yangqigou Rocks of the Jiepaiyan Formation of the Xiahe Group of the Middle-New Proterozoic.The article introduces the geological background and lithofacies structural characteristics,morphological occurrence,rock types,chemical composition,formation age and genesis of the Yangqigou peridotite rock body,and analyzes the performance of ore processing technology and product application.The Yangqigou peridotite deposit is exposed to the surface and is easy to mine.The peridotite can be used in refractory materials,foundry industry,agricultural fertilizers,construction industry,engineering ceramics,handicrafts,acidified peridotite leaching magnesium and other industries.Through the following study of Yangqigou peridotite deposit,the article provides a geological basis for the rational development and utilization of peridotite mineral resources in Yangqigou.
