在奇瓦瓦东部、杜兰哥东部以及萨卡特卡斯这些地段。高数值的热流(2.3—2.9HFU)(1HFU=μcal/cm~2=41.8mw/m~2(和剩余热流)1.2—2.1HFU)说明。横越北墨西哥的中部高原.可能存在一个南东倾向而不连续的初始裂谷.从这一带计算的等温线来看.中部高原的数值是升高的.并显示大概相继于东马德雷山脉西部边缘的模式。在奇瓦瓦东部和杜兰哥——萨卡特卡斯中部,1000℃的等温线延伸到20到30公里深部之间。在东西剖面,从中部高原下部放出的高温到东马德雷山脉下面的中温,其数值显示出急剧变化。这些地热的分布形状与格兰德河裂各地带的地理连续性.完全表明了两种特征之间的关系。
East of Chihuahua, east of Durango and Zacatecas. High numerical heat flow (2.3-2.9HFU) (1HFU = μcal / cm 2 = 41.8mw / m 2 (and residual heat flow) 1.2-2.1HFU). Across the central plateau of northern Mexico, there may be a south-easterly and discontinuous initial rift that, viewed from the isotherms calculated in this zone, shows an increase in the central plateau and is roughly at the western margin of the eastern Sierra Madre Mode. In the eastern part of Chihuahua and in the middle of Durango-Zacatecas, the 1000 ° C isotherm extends between 20 and 30 km deep. In the east-west profile, the high temperature released from the lower part of the Central Highlands to moderate temperatures below the eastern Madre Mountains shows dramatic changes. The geographical distribution of these geothermal and the geographical continuity of the Grand River crack completely shows the relationship between the two characteristics.
