摘要
用于地质应用的裂变径迹分析涉及一系列实际考虑因素.其中包括现场采样,常用矿物的分离,这些矿物的制备以供分析以及所需基本参数的测量.本次文章主要从多种矿物的蚀刻条件来进行综述.自发裂变径迹是通过化学蚀刻在矿物颗粒中揭示出来的,因为蚀刻剂优先蚀刻径迹核心中高度无序的部分.矿物中的整体蚀刻速率并不均匀,并且在不同的晶体学方向上会有所不同,因此,径迹的形状和大小会有所不同,为了更加有效的观察和统计径迹,选择合适的蚀刻条件是非常重要的.
Abstract
Fission track analysis for geological applications involves a number of practical considerations.These include on-site sampling,separation of commonly used minerals,preparation of these minerals for analysis and measurement of the required basic parameters.This article mainly reviews the etching conditions of various minerals.The spontaneous fission track is revealed in the mineral particles by chemical etching,because the etchant preferentially etches the highly disordered part of the track core.The overall etching rate in the mineral is not uniform and will vary in different crystallographic directions.Therefore,the shape and size of the track will be different.In order to observe and count the track more effectively,it is very important to select the appropriate etching conditions.
