Research Progress and Application Examples of Ternary Mapping of Continental Volcanic Rocks

应用"火山构造-岩性岩相-火山地层"三位一体填图方法,以火山构造单元为范围来研究岩性岩相,建立地层层序和骨架,填制的地质图及火山岩相构造图,火山构造面貌清楚、层次分明、具较强立体感,能全面反映不同时期、不同阶段火山作用特点和演化规律,能客观、合理地反映火山作用过程。

The trinity mapping method of ＂volcanic structure, lithologic lithofacies and volcanic stratigraphy＂ is applied to study lithologic lithofacies in the range of volcanic tectonic unit, to establish stratigraphic sequence and framework, to construct geological map and volcanic facies structural map. The geological map shows that the volcanic tectonic features are clear, the layers are clear. It has a strong three-dimensional feeling. The maps can reflect the characteristics and evolution law of volcanism in different periods and stages, and can objectively and reasonably reflect the process of volcanism.
