| 摘 要： | 中俄双方技术人员在额尔古纳地区上护林盆地进行了１：２．５万比例尺的立体地质填图，这种以找矿模式为指导，以全面查明盆地地质构造特征为目的的立体地质填图有如下几个特点：（１）超前编图，提高填图工作的目的性；（２）地表精细地质填图，以填岩性图、蚀变图为重点，密切配合放射性测量；（３）作构造物探剖面，将物化探成果转化为地质语言；（４）布设基准孔，了解盆地深部地质构造特征。

| Abstract: | Stereoscopic"geological mapping(scale 1: 25000)was carried out in Shanghulin Basin in Ergun area by both technical personnel from China and Russia. This kind of "stereoscopic"geological mapping,guided by prospecting model and aimed at overall investigating the geological structural characteristics of the basin, is characterized by the following features: 1.Compiling the geological map in advance in order to highlight the objective of geological mapping;2. Detailed surface geological mapping with emphasis on lithologic mapping and alteration mapping and in close coordination with radiometric survey; 3. Structural geophysical profiling to transform geophysical and geochemical exploration results into geologese;4. Laying out base hole to understand the geological structural characteristics in the depth of the basin. |
