摘要
用荧光光度术详细地研究了滇西镇安盆地泥炭、软褐煤中的树脂体。结果表明,泥炭、软褐煤中的树脂体具有非常复杂的荧光特性。首先来说,其荧光颜色多样,从绿至红均有,但以绿至黄为主。不同荧光颜色的树脂体其I546不同,介于28-<1之间,从绿色荧光到橙色荧光,I546逐渐减小。短波技荧光呈现负变化;长波长荧光呈现正变化。树脂体的荧光光谱亦非常复杂:单峰或三峰,λmax=48h-67hnm;Q=h.h85-7.854。随激发照射时间增长,绿色荧光树脂体的光谱会向长波长方向“漂移”。
A detailed study by means of fluorescence on the resinite in the peat and soft brown coal ftom thezhenan basin,Western Yunnan, has been made. The results show that the fluorescence feature of theresinite is considerallly comp1iCated. The fluorescence color of the resinite is ftom green to red, principally, from green to yellow. The I546 of different fluorescence resinites is in the range from 1 to 28; theshort wavelength fluorescence resinite has negative alteration in I546;nevertheless,the long wavelengthfluorescence resinite has posithe alteration in I546. The fluorescence spectra of the resinite is also considelably complicated;one or three peaks; λmax ranging from 480nm to 670nm;Q from 0. 085 to 7. 854.With time of exiting increasing,the fluorescence spectra of the green fluorescence resinite mny 'shift'from short wavelength to long wavelensth.
