本文应用沉积剖面内煤的品级与沉降史和地热条件之间的经验关系估算了德国南部某些地方的地热梯度。大多数所调查的钻孔位于上莱茵地堑中部。早第三纪(高于78℃/公里)比晚第三纪(高于49℃/公里)的地温梯度要高一些。近代的地温梯度(高于77℃/公里)也高于所估算的晚第三纪地温梯度。 Urach3号井的煤的品级反映出一种与所测地温梯度(46℃/公里)相一致的地热体制。磨拉石槽地中的两个钻孔显示出第三纪期间有低而恒定的地热体制(23°到25℃/公里),它与现今地热体制是一致的。
This paper estimates the geothermal gradient in some parts of southern Germany by using the empirical relationship between coal grade and sedimentation history and geothermal conditions in the sedimentary section. Most of the boreholes surveyed are located in the middle of the Upper Rhine graben. Early Tertiary (above 78 ℃ / km) than the late Tertiary (higher than 49 ℃ / km) geothermal gradient higher. Geothermal gradient in modern times (higher than 77 ℃ / km) is also higher than the estimated temperature gradient of Late Tertiary. The grade of coal in Urach No.3 well reflects a geothermal system consistent with the geothermal gradient measured (46 ° C / km). The two boreholes in the mola-trough show a low and constant geothermal regime (23 ° to 25 ° C / km) during the Tertiary period that is consistent with current geothermal regimes.
