为了根据初始行星物质来揭示洋壳和陆壳的主要化学演化趋势,我们将这些体系中元素的相对浓度与它们的一些特性:丰度、密度、熔点及对 O、S 和 Fe的相对亲合性(亲石性、亲铜性和亲铁性)进行了比较(图1)。在本文中,主要初始行星物质的组成,被视为与陨石(μ)的相同,根据陨石坠落地面的情况,其中石质陨石占94%,全属陨石占6%。洋壳的组成与玄武岩(υ)的一致。粘土页岩(c)按其组成则属于陆壳沉积岩中的一种分布最广泛的特殊类型。因
In order to reveal the main chemical evolution of the oceanic crust and the continental crust based on the initial planetary material, we compare the relative concentrations of elements in these systems with some of their characteristics: abundance, density, melting point, and relative affinity for O, S, and Fe (Stone, copper affinity and iron affinity) (Figure 1). In this paper, the composition of the main initial planets is considered to be the same as the meteorite (μ), where the stone meteorites account for 94% and the all-meteorites account for 6%, depending on where the meteorites fall to the ground. The composition of the oceanic crust is consistent with the basalt (υ). Clay shale (c), by its composition, belongs to the most widely distributed and special type in continental shelf sedimentary rocks. because
