| 摘 要： | 在室内对新疆塔里木盆地西北缘柯坪地区碳酸盐岩的反射光谱进行了测量。分析结果表明：碳酸盐岩的特征吸收谱带位于２３００～２３５０ｎｍ，随着碳酸盐岩中Ｍｇ２＋含量的增加，其特征吸收谱带的中心波长位置具有向短波长方向移动的特点；同时，随着碳酸盐岩中碳酸盐矿物含量的增加，其特征吸收谱带的深度（Ｄ）也有增大的趋势，并且岩石的平均反射率（Ｒ）也随着增高。根据这些特征可以判定碳酸盐岩的岩石类型及碳酸盐矿物的相对含量

| Abstract: | A study on reflectance spectra features of carbonate rocks form the Kalpin Uplift, NW margin of Tarim Basin is carried out. The results indicate that carbonate rocks have characteristic absorption band between 2 300 to 2 350 nm due to CO 2- 3, and that the depth of absorption band( D ) and average reflectivity of the rocks are increased with carbonate mineral content. And also the band center moves to shorter wavelength with the incraese of Mg 2 content. Based on these characteristics, the different kinds of carbonate rocks and relative content of carbonate minerals can be effectively distinguished. |
