台湾软玉的矿物成分、显微结构特征及形成世代
Mineral Composition, Microstructure Characteristics and Generation of Taiwan Nephrite
摘要
Abstract
The nephrite samples from Hualien Fengtien nephrite belt of Taiwan are studied by Fourier transform infrared absorption spectra and XRD, indicating that the nephrite samples are mainly composed of tremolite. The major absorption frequencies of the samples appear around 940 -1 105 cm-1, 650 -760 cm-1, 460 -510 cm-1 and 3 670 cm-1, and the main X-ray spectrogram are 0. 844 3 -0. 845 8 nm( 110) , 0. 271 1 -0. 271 5 nm(151) , 0. 313 1.-0. 313 5 nm(310) and 0. 328 3 -0. 328 6 nm (240).The microstructures of nephrite are felt-like blastic texture, columnar blastic texture, bundle-like blastic texture and parallel fibroblastic texture. The tremolite went through four different generations. The first is coarse columnar. The second is fine columnar, interspersed among the first generation. The third is felt-like aggregate. The fourth is parallel fiber-shaped, formed in last stage.关键词
