Identifier: http://hdl.handle.net/1959.14/201696
Description: Podiform chromite deposits occur in ultramafic-mafic bodies scattered along the Pacific coast of Mexico. However, some important features of these chromite deposits, such as the nature of their parent ... More

Identifier: http://hdl.handle.net/1959.14/208545
Description: The Western Yukon contains an assemblage of schists, basalts and ultramafic rocks. The basalts were recently dated (U-Pb zircon) as Lower Permian (282 Ma, Escayola et al, in prep). The ultramafic mass ... More

Identifier: http://hdl.handle.net/1959.14/208665
Description: Chromite is a well-established indicator for the petrogenesis and geodynamic setting of ultramafic rocks. However, despite of its higher resistance to alteration relative to other minerals, its chemis ... More

Identifier: http://hdl.handle.net/1959.14/208803
Description: Xenolithic eclogites are high-P/T garnet-clinopyroxene rocks brought to the surface by kimberlites and other primitive magmas. Their origins are controversial: do they represent subducted oceanic crus ... More

Identifier: http://hdl.handle.net/1959.14/211790
Description: A U-Pb/Hf-isotope study of >16,000 zircons shows that 70% of Earth's continental crust probably formed in Archean time, and much probably is >3 Ga old. The model ages (TMA ) of ca 500 low-Re/Os sulfid ... More

Identifier: http://hdl.handle.net/1959.14/211800
Description: Geochemical and geological evidence suggests that subduction processes, critical for the formation of many magmatic and hydrothermal ore deposits, have been active since about 3.9Ga. The emergence of ... More
