长白山地区黑曜岩地质特征及宝玉石特性研究

长白山位于华北地台东缘,是国内唯一的复合型火山.区内断裂构造发育,火山运动频繁,其独特的中心喷发方式,形成了独具特色的长白山黑曜岩.文章从长白山火山地质特征入手,通过对样品检测、分析研究,揭示了长白山黑曜岩产出特征、高温高压形成机理,及具有高能量、强吸附、弱电磁、富含微量元素的特性,得出了其为国内独有的宝玉石、养生保健石的结论.

STUDY ON THE GEOLOGY AND GEMSTONE CHARACTERISTICS OF THE OBSIDIAN FROM CHANGBAISHAN MOUNTAIN

Changbaishan Mountain,situated in the eastern margin of North China platform,is the only composite volcano in China.The regional fractures are developed,with frequent volcanic movement.The central eruption of the volcano formed the exceptional Changbaishan obsidian.On the basis of the volcanic geologic characteristics of Changbaishan region,with testing and analysis of obsidian samples,this paper reveals its occurrence,forming mechanism of high-temperature and high-pressure,as well as the characteristics of high energy,strong adsorption,weak electromagnetism and rich content of microelements.It is concluded that the Changbaishan obsidian is a specific gemstone with health care function.
