Some suggestions for the improvement of the regional geological mapping system and practical skills
摘要
Abstract
The Regional Geological Mapping System, well operated in terms of its function and utilization, was briefly discussed in this paper. The authors found in its application that this system has some shortcomings, first, in the process of measuring the regional geological section, the increasing inaccuracy due to the increasing length of the section will finally lead to the remarkable deviation of the end of the section from its actual one because of the inaccuracy in measuring the azimuth angle, grading angle and slope length. Second, before the measurement of the section in a radioactive ore district, we need to measure the y- ray spectrometry, but the resultant data can' t be involved in the Regional Geological Mapping System. Third, the stratigraphic thickness of the special section will not be included in the calculation of the thickness of the strata in the Regional Geological Mapping System (RGSETION). For example, it's probable that some lines go backward while most of them continue going in their original direction. If this really happens, the thickness of the strata of these lines that go backward will be calculated again. Fourth, the attitude measured by the digital geological compass should be transformed in the tablet, but the use of the digital geological compass will be greatly limited because it can' t directly display the attitude measured by it itself. For solving these problems, the authors put forward some suggestions in this paper. In combination with the experience obtained in the field and indoor work concering the utilization of the Regional Geological Mapping System, the authors also illustrate some practical skills in this paper.关键词
