探究地球和谐代谢岩浆活动和地热之源Exploring Magmatism in the Harmonious Metabolism of the Earth: An Endless Source of Geothermal Energy

摘要(Abstract):
地热能是一种新型清洁能源。现阶段对地热能来自地球内部岩浆的认识基本一致,但对岩浆活动的深部过程缺少探讨,不了解地热资源分布的控制因素,给地热能勘查带来了难度。提出地球公转和自转对地球产生压力,造成岩浆对地壳顶蚀作用而率先在深大断裂带出现管涌,继而沿不同序次断裂带连通后形成立体管网状的岩浆径流循环体系,岩浆沿岩浆河主要从赤道趋向两极径流,再潜回地幔。建立了地球物质代谢、能量代谢和地热能来源结构化模型,论证了岩浆活动是地热能的源头,也是地震和火山喷发的动力致因。反演了岩浆径流系统对地热能空间分布的控制作用,推论地热能在地表以下几千米至几十千米深度范围内主要是沿着岩浆径流方向呈横向状态赋存的,与深大断裂带走向相一致。
