| 摘 要： | 为重力调查、地震勘探以及地质研究提供基础性数据,笔者通过收集、整理区域物探、矿区物探等前人工作中已获得的物性数据以建立河南省岩石物性数据库,以此为基础对河南省33 070个岩石密度数据进行了数理统计,给出了全省全岩、各岩石大类、类、亚类的密度统计值,并发现它们之间具有不同程度的差异性,可供在河南省境内开展相关地质调查工作时参考使用。

| Abstract: | By collecting and sorting out previous physical data from regional and district geophysical exploration to establish petrophysi-cal database of Henan Province, this paper provided basic data for gravity survey, seismic exploration and geological research. On such a basis, mathematical statistic analysis was done for the density data of totally 33 070 rocks within Henan Province, and the density sta-tistics of total rocks of the whole province were presented. It is found that there exist varying degrees of differences between big groups, groups and subgroups, and these differences can be used as references in geological survey of Henan Province. |
