Peridotite weathering is the missing ingredient of Earth’s continental crust composition

Nature Communications, 2018
The concentration of Ni and Cr of the continental crust cannot be explained by formation models involving differentiated magmatic rocks. Here, the authors show that hydrothermal alteration and chemical weathering of ultramafic rock compensates for the ...
