Why is the Earth's F Cl ratio not chondritic?
Primitive chondrites, un-molten stony meteorites, are believed to be the building blocks of the Earth. Because terrestrial planets have experienced chemical differentiation in the core, mantle, and hydrosphere, the elemental abundance pattern of some elements at the planetary surface is not chondritic. In other words, the non-chondritic abundance pattern of elements on the planetary surfac
