浅谈区域岩石物性调查的必要性和可行性

本文在总结我国开展区域岩石物性调查状况之后,给出区域岩石物性调查定义,阐述了开展区域岩石物性调查的必要性和可行性.区域岩石物性调查,在区域上有计划地进行,强调采样的整体性(不缺少岩性系列)和代表性(突出各系列重点岩性),采用综合物性测定和研究的方法,进行多方面相关关系研究.它不同于常规物性工作,具有更深刻、更广泛实际的意义.它能为区域地质调查,区域物、化探设计和解释,以及解决某些特定地质问题提供基础资料,现阶段开展区域岩石物性调查势在必行.

A PRELIMINARY DISCUSSION ON THE NECESSITYAND FEASIBILITY OF CARRYING OUT PHYSICAL PROPERTY SURVEY OF REGIONAL ROCKS

Following a summarization of the state of regional rock physical property surveyin China,the present paper has given such survey a clear definition and sets forth its necessity and feasibility. The regional rock physical property survey should be carried out inaccordance with a plan, the integrity (i. e., no lfthologic series being absent) and represeotativeness (i. e. key rocks in various series being made prominent) of sampling must be emphasized, and the method for integrated physical property determination and investigationought to be adopted so as to carry out correlative studies of various aspects. Unlike the routine physical property work, such survey has a more profound and extensive practical significance. It can provide basic data for regional geological survey, design and interpretationof regional geophysical and geochemical prospecting, and solution of some specific geologicalproblems. It is thus absolutely necessary to conduct ragional rock physical property surveyat the present stage.
