激光显微光谱分析法考查锡矿带脉石中微量元素的赋存状态

本文根据各种元素的原子被激发以后部可以产生一组特征谱线,且当元素含量不太高时,谱线的强度与元素的含量成正比关系,以jf l矿物的蒸发量的多少,对矿物内各元素含量之间的相对比值不产生影响等条件,利用矿物中微量元素与载体矿物中相似元素的谱线黑度值之间,消长关系来考查矿物中微量元素的贼存状态。

EXAMINATION ON MIOROELEMENT OCCURRENCE STATE OF VEINSTONE IN TIN ORE ZONE WITH LASER MICROSPECTROSCOPY

This paper is writlon on the basis of thc iollowing fact: each kind of the element will emit a group of characteristic spectrum when its atoms are stimulanted.When the element concentration is not too high,spectrum intensity is proportional to the element concentra- tion.Furthermore,the vaporization amount of the ore does not affect the relative ratio between the different element concentrations in the ores.
