根据研究区的现今地表温泉温度、地温梯度、地表热流值及地壳结构，恢复了古地热场，计算了各期岩浆活动产生的瞬时古地温梯度，初步探讨了研究区的热源及有机质热演化史。指出地幔热流是控制区域性地热场的主要因素，岩浆热流控制了局部高地热场的分布，构造活动产生的剪切热流对俯冲带及剪切带的瞬时古地热场有重要影响。研究区的有机质成熟度在总体处于过成熟的背景下，仍存在局部的成熟或成熟晚阶段的异常区，有可能成为最重要的含油气远景区
Based on the current surface temperature, geothermal gradient, surface heat flow and crustal structure in the study area, the paleo-geothermal field was restored and the instantaneous paleogeothermal gradient generated by each period of magmatic activity was calculated. The heat source and thermal evolution history of organic matter in the study area . It is pointed out that the mantle heat flow is the main factor controlling regional geothermal field. The magmatic heat flow controls the distribution of local high geothermal field. The shear heat flow generated by the tectonic activities has an important influence on the transient paleotemperature of the subduction zone and shear zone. Organic Matter Maturity in the study area is still in the background of over-maturity in general, and there are still some anomalous areas in the mature or mature late stage of the study area, which may become the most important oil-gas prospect
