| 中文摘要:地球科学发展到今天, 中外所积累的实际资料之多早已达到一个临界点, 必然要从量变跃迁为理论认识上的质变。本文是这方面的一个尝试, 力图把地球看成一个整体, 提出以下五条地球内动因基本规律: (1) Na、K被幔汁的带入乃是地幔和地壳中产生各种类型岩浆的关键要素; (2) Na、K碱交代作用是整个热液作用中最重要的一个反应机制; (3) 大地构造源于幔壳溃变**(是幔汁在起主要作用); (4) 在地球的演化上, 地壳乃是地幔亏损(depletion)部分的向上分化、搬家, 地壳=原始地幔－亏损地幔; (5) 地球深部的Na、K流(即幔汁主体)是来自威力更大的地核氢(H+、H、H2)流的萃取和驱动。 |

| Abstract:This paper attempts to summarize the achievements in geodynamic studies as a whole. Five dynamic principles of the Earth are put forward in this paper: (1) the introduction of Na and K to any kind of rocks is the key to magma genesis; (2) Na-and K-metasomatism is the most fundamental mechanism in whole hydrothermalism; (3) geotectonic movement results from mantle-crust asthenospherization, which is stimulated by Na-and K-metasomatism; (4) the evolution of the Earth is represented by two processes: ① the depletion of the mantle and ② the formation of the crust. The crust is equal to original mantle minus depleted upper mantle; (5) Na-and K-fluids (namely, mantle ichors-HACONS) are derived from deep hydrogen (H+, H, H2) flow extraction from the mantle. |
