【摘要】：吉林通化集安地區(qū)發(fā)現(xiàn)了儲量較大的蛇紋石質(zhì)玉石礦床.X射線熒光光譜分析(XRF)顯示蛇紋石質(zhì)玉石中Si O2含量為35.21%~37.18%,Mg O 46.94%~49.72%,Fe O/Fe2O3之比在0.174~0.685之間.XRD分析顯示在0.733 nm、0.366 nm和0.250 nm處存在有利蛇紋石的特征衍射峰.集安蛇紋石質(zhì)玉主要礦物為利蛇紋石,并常含有鎂橄欖石.紅外光譜顯示在3 650~3 700 cm-1、950~1 100 cm-1、400~700 cm-1存在有特征的利蛇紋石吸收峰.本玉石礦床屬區(qū)域變質(zhì)型蛇紋石礦床,利蛇紋石應(yīng)為橄欖石在低溫條件下水熱蝕變的產(chǎn)物.
[Abstract]:X-ray fluorescence spectroscopy (XRF) analysis of serpentine jade deposits in Tonghua Ji'an area, Jilin Province shows that the content of Sio 2 in serpentine jade is 35.21 100% and 37.18% respectively. The ratio of mg O 46.94 and mg O 46.94 to Fe O/Fe2O3 is between 0.174 and 0.685. XRD analysis shows that the content of Sio _ 2 in serpentine jade is between 0.366nm and 0.250 nm. There is a characteristic diffraction peak in favor of serpentine. The main mineral of chrysotile jade in Ji'an is serpentine, and often contains forsterite. Infrared spectra showed that there was a characteristic absorption peak of serpentine at 3 650 cm-1950~1 100 cm-1400~700 cm-1. This deposit belongs to the regional metamorphic serpentine deposit, and serpentine should be the product of low temperature water thermal alteration of olivine.
