| 摘 要： | 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

| Abstract: | The authors calculate the twinkling paleogeothermal gradient created by various ages magmatic activity and briefly discuss the heat sources and thermal evolution of organic matter,according to the present surface temperature of hot spring,geothermal gradient,surface heat flow and crustal structure in the surveyed area.The mantle heat flow controlled regional geothermal field,the magmatic heat flow controlled high geothermal field in the local areas,the shear heat flow created by tectonic activity made a notable impact on the twinkling paleogeothermal field of the subduction belts and shear belts.In general,the organic matter in the studying area is in the supermature setting,the local abnormal areas in mature or late mature stage might be the best important prospective oil gas lands in the area. |
