摘要
本文在阐述四川雅安地区红色花岗石石材产出的区域地质特征的基础上。重点探讨了由自变质作用生成的鸡爪纹在时间、空间上的变化规律,由于自变质作用程度不同,而产生了由北至南,即由宝兴、芦山、天全,至汉源、荥经、石棉等地的鸡爪纹从极少到有的变化规律,从而更好地指导本地区花岗石石材的找矿和应用。
The paper describes the district geological character of the red granite stone in Ya＇an, Sichuan, and discusses variety regulation of ＂claw-veins＂ which was created by self-metamorphism on time and space. Due to varying degree different of self-metamorphism, ＂claw-veins＂ graw out of few from BaoXing,LuShan, TianQuan to Rong, Jing,HanYuan,ShiMian, and guides better to search and apply the red granite in the area.
