Abstract:

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。

[40]  注:任何含氧岩石中O~(2-)大体积阴离子(离子半径大到1.36A),占全岩体积近2/3,所有阳离子总平均离子价必然也等于+2,以此和O~(2-)的-2价电荷平衡.一旦大量一价Na~+、K~+带人岩石,阳离子平均离子价将小于+2,此时必然要求高于二价的Al~(3+)和Si~(4+)带人进行电价补偿.原有两个Mg~(2+)(如超基性岩)被2个其它离子(一个Al~(3+),一个Na~+)取代,电荷仍然等于4+不变,2×2=1+3,此即价歧化;或者3个Mg~(2+)被一个Na~+一个K~+和一个Si~(4+)取代,3×2=1+1+4
