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.
