Geochemistry and Os-Nd-Sr isotopes of the Gaositai Alaskantype ultramafic complex from the northern North China craton: implications for mantle-crust interaction
We report petrological, chemical and Os-Nd-Sr isotopic data for the Gaositai ultramafic complex from northern North China craton (NCC) to reveal its petrogenesis. The complex shows features of Alaskan-type intrusions, including (1) the concentric zoning from dunite core, to clinopyroxenite and hornblendite in the rim, and the common cumulative textures; (2) the abundance of olivine, clinopyroxene and hornblende, and the scarcity of orthopyroxene and plagioclase, and (3) the systematic decrease...[Show more]
