CONTROLLING MECHANISMS FOR MANTLE CREEPFLOW AND GEOTHERMAL ENERGY BUDGETS:INSIGHT FROM HISTORISTIC-CAUSATIONIST GEOTECTONICS

本文从地热学的角度探讨历史—因果论大地构造的驱动力地幔蠕动热能聚散的规律.以云南的大地热流研究为实例,论证了大地热漉、发幔热流高的地区壳体活动性强.认识壳体的活动性及地幔蠕动规律的关键在于正确分割大地热流,获得反映大地构造背景的地幔热流.地幔热流的变化是地幔蠕动的真实反映.

An analysis of Yunnan province S.W.China reveals that mantle creep-flow and terrestrial heat flow determined from conservation of heat considerations (geothermal energy budgets)can be integrated within the context of a historistic-causationist geotectonic viewpoint.Within this province which has active crustal movements are both high terrestrial and inferred mantle heat flows.A key to the recognition of the mutual activities of crustobodies and accompanying mantle creep is determined through the budget of partitioning terrestrial heat flow.Through this partitioning,one can obtain mantle heat flow indica- tive of the respective tectonic setting and directly related to mantle creep.
