| 摘 要： | 南阳独山玉是中国四大名玉之一,矿床产于次闪石化辉长岩体内。本文在野外工作的基础上,通过对矿床地质特征的总结,研究了玉化带、玉脉密集体、玉脉的分布特征和规律,划分了五种玉脉类型。初步探讨了矿床成因,提出了岩浆分异作用、动力变质作用、热液蚀变是成矿的主要地质作用。

| Abstract: | Nanyang Dushan chalchiguite is one of China’s four famous jades.The ore deposit occurs in gabbro rocks with hypoamphibole alteration.On the basis of fieldwork and research on the features and regularity of the jade mineralizing zone and jade veins,the paper summarizes geological characteristics of the ore deposit,dividing the veins into five vein type.It discusses the genesis of ore deposit preliminarily,putting forward that magma fractionation,metamorphism,hydrothermal alteration are the main mineralization. |
