应该重视岩(矿)石物性标本采测的代表性

Importance of Representativeness of Rock (Ore) Physical Property Simple Collection and Test

在贵州山区沉积岩层厚、碳酸盐岩十分发育、风化严重、岩性复杂多变,给地球物理勘查工作中野外岩(矿)石物性标本采测造成困难,一些地区甚至因自然条件的原因戓人为因素造成物性数据失去真实性、代表性,使物探异常解释出现误判。针对贵州物探工作中岩(矿)石物性标本采测存在的问题,本文提出岩(矿)石物性工作应该重视标本的代表性,以提高物性数据的精准度,充分发挥其在异常研究及异常解释上的作用。

In the mountain area of Guizhou,the sedimentary rock is thick,the weathering is serious and the lithology is complex,it makes difficult for field rock property collection and test in geophysical prospecting.In some area,for the natural or human reason,the property information is not realistic and representative,the explanation of geophysical anomaly usually wrong.In this paper,it's thought that the representation of simples should be paid more attention for rock property study,so the information accuracy will be improved,the function in anomaly study and explanation will be given effectively.
