基于碳、氦一体的思想，利用C－He同位素示踪体系辨识He、CO2气体的来源和碳的地球化学循环。在我国首次将C－He体系应用于流体地球化学的研究。通过对我国东北温泉出露地区的野外地质调查、气体组分和He、C同位素的分析，以及西藏、云南等地区的He、C同位素数据的系统综合分析 Based on the idea of ​​carbon and helium, C-He isotope tracing system is used to identify the source of He and CO2 gas and the geochemical cycle of carbon. For the first time in our country, the C-He system is applied to the study of fluid geochemistry. Through the field geological survey, gas composition and He, C isotope analysis of the hot spring outcrop in northeastern China and systematic analysis of He, C isotope data in Tibet, Yunnan and other regions
