【摘要】 根据阴极发光测试所得结果,岩浆成因和沉积成因的碳酸岩在阴极发光特征上有很大差异.沉积成因的碳酸盐岩阴极发光强,颜色鲜艳,为桔红—桔黄色:岩浆成因的碳酸岩阴极发光弱,颜色暗或不发光,一般为黑褐色.阴极发光测试结果,与野外观察及室内其它测试手段如碳氧同位素分析、电镜、包体测温、稀土元素等到试结果吻合.应用阴极发光手段方法简便、效果明显,可作为区分碳酸盐岩与碳酸岩的辅助手段之一.更多还原

【Abstract】 Based on results identified by cathodoluminescence, the differences of character of cathodoluminescence between carbonate rock and carbonatite genesis and sedimentary are as follows: the carbonate rock displays that light of cathodoluminescence is strong, and color is bright (from orange-red to orange-yellow ) , carbonatite is weak and dark (black-brown) . The result identified by cathodoluminescence is compatible with the results of isotopic analysis. SEM and REE pattern. Technology of athodoluminescence can be applied conveniently, as an auxiliary method, which can identify the carbonate rock and carbonatite.更多还原
