陆相火山地层研究方法——“火山构造-岩性岩相-火山地层”三位一体

“火山构造-岩性岩相-火山地层”三位一体研究方法强调剖面研究必须与路线调查相结合,火山地层研究必须与火山岩相及岩性、火山构造研究相结合,按火山构造单元为范围建立火山地层层序和格架.通过1∶25万周宁县等4幅区域地质调查项目的实践,建立的火山地层格架客观、合理,火山构造面貌清楚、层次分明、具较强立体感,全面反映不同时期、不同阶段火山作用特点和演化规律,显著提高了火山地质研究程度.

Process of Nonmarine volcanic sequence research "Volcanic structure-lithologic lithofacies-volcanic sequence" trinity research process

＂ Volcanic structure-lithologic lithofacies-volcanic sequence＂ trinity research process insists that the lateral section research must combine with route survey, volcanic sequence research must combine with volcanic lithologic, lithofacies and structure research, then according to the volcanic structure units range establishes volcanic stratigraphic sequence and framework. Base on the Zhouning County Etc. 4 regional geological surveys in the scales of 1 ： 250, 000, it had been established volcanic sequence framework which is objective and rational , and the volcanic structure had stong stereoscopic sensation which had clear face and sharp arrangement. Roundly reflect the volcanism character and evolutive rule in different times and different stages, and evidently improve the degree of volcanic geology research.
