geochemical cycle
The sequence of stages in the migration of elements during geologic changes. Rankama and Sahama distinguish a major or endogenous cycle, proceeding from magma to igneous rocks to sediments to sedimentary rocks to metamorphic rocks and possibly through migmatites back to magma, and a minor or exogenic cycle proceeding from sediments to sedimentary rocks to weathered material and back to sediments again.
