深化解释提高区域重力调查的地质效果

DEEPENING INTERPRETATION AND RAISING GEOLOGICALEFFECTS OF REGIONAL GRAVITY SURVEY

十年来区域宽力调查完成了大量的工作,取得了一批成果,特别是编制了符合“五统一”要求的图件,解决了不少地质问题,但资料研究和解释中存在不少问题。深化解释是区域重力调查工作发展到今天的客观需要。本文指出深化解释的目标是解决更多的基础地质问题和矿产预测问题,特别是工作区内的关键问题。对重力资料深化解释和重力与其他方法资料进行综合解释,以及地质解释深化提出了要求。另外还对重力资料的处理和某些解释方面的技术问题提出了看法。最后就实现深化解释应采取的措施提出了建议。

Abstract Over the past ten years, much work has been done in the field of gravity survey, which yields quite a number of outcomes. The compilation of maps in line with the principle of 'unity in five aspects', in particular, helps to solve many geological problems. Nevertheless, as lots of trouble still exist in the study and interpretation of the data, the deepening of interpretation is beco ming the objective necessity when the regional gravity survey has developed to the present situation. It is pointed out that the aim of deepening interpre tation is to solve more basic geological and ore prognostic problems, especially the key problem in working area. Some requirements have been posed for the deepening of gravity data interpretation and the integrated interpretation of gravity and other data as well as the deepening of geological interpretation. In addition, the author advances his opinions concerning the gravity data processing and some technical problems in interpretation. At last, he puts forward some suggestions about the measures that should be taken for realizing the deepening of interpretation.
