WebTheir name comes from their relatively low iron abundance, with respect to the H chondrites, which are about 20–25% iron by weight. Historically, the L chondrites have been named hypersthene chondrites or olivine hypersthene chondrites for the dominant minerals, but these terms are now obsolete. Chemical composition [ edit] WebOct 7, 2016 · Any smooth chondrite-normalized REE pattern can be referred to using the convention Λ = {λ 0, λ 1, λ 2,…}, with as many terms as necessary. To give some specific examples, the Bulk Silicate Earth (BSE) composition of Palme & O’Neill (2014) has Λ = {ln(2·83), 0, 0}, where 2·83 is the factor by which the refractory lithophile elements ...

Web“Rare Earth Plots” and the Concentrations of Rare Earth Elements (REE) in Chondritic Meteorites Randy L. Korotev. The following sets of concentration values have been used in the geochemical literature for the purpose of preparing plots of “chondrite-normalized” concentrations of REE against atomic number or inverse ionic radius. WebThe most abundant constituents of chondrites are chondrules, which are igneous particles that crystallized rapidly in minutes to hours. They are composed largely of olivine and pyroxene, commonly contain metallic Fe,Ni and are 0.01-10 mm in size. Some chondrules are rounded as they were once entirely molten but many are irregular in shape ...
