摘要
矿物是自然界中最常见的物质之一,也是土壤的主要组成部分,通过对土壤中所含矿物的种类、组合特征及含量进行分析,并结合土壤中其它组分的检验,可以实现对土壤物证的比对检验,也可对土壤的来源进行推断,为案件侦破提供方向和证据。本文介绍了在法庭科学领域土壤中矿物检验的意义以及国内外检验技术的研究进展,对我国矿物物证检验研究提出了建议。
Mineral,ubiquitous in the Earth and most abundant in soil,is therefore one kind of common evidence.Mineral is also of strong transferability and significant regional traits.Thus,soil evidence can be identified along with its provenance through the determination of both the composition and content of the mineral in soil so that the relevant criminal investigation can acquire the necessary clue.This paper analyzes the significance of mineral examination for forensic science,and summarizes the research progress in analysis of mineral evidence.
