The discovery and a preliminary study of Dahua tremolite jade in Guangxi

The tremolite jade newly found in Dahua County of Guangxi was studied by such means as polarizing microscope, X-ray diffraction, electron microprobe, infrared spectrum and scanning electron microscope. The results show that the major mineral composition of Dahua tremolite jade is tremolite. A study of the texture and structure shows that its major texture is almost the same as that of Hetian jade, suggesting that Dahua tremolite jade is also a typical tremolite jade. It could be classified as gemstone according to its gemological characteristics, and it has been carved into ornaments for selling on the market. The genesis of the jade and the significance of its detection are also discussed in this paper.
