δ 26Mg do not correlate with SiO 2 or MgO contents, suggesting homogenous Mg isotope compositions in igneous rocks at the level of current precision, relative to low temperature samples including sediments and riverine and sea waters. Our data do not support a non-chondritic Mg isotope ...

The Bowers and Shirshov Ridges (hereafter BR and SR, respectively) are two prominent submarine structures ofunknown age and provenance in the Bering Sea. So far only a few geochemical data exist on the composition ofbasement rocks from the SR (Silantyev et al., 1985) and none for the BR...

Assuming sediments to derive exclusively from granite-granodiorite and basalt the chemical composition of the "average igneous rock" is found to be almost identical with that of the Appalachian and Cordilleran igneous rocks as determined by A. Knopf (1916). The total amount of weathered igneous roc...

present. Gabbro, a mafic intrusive igneous rock which solidifies beneath the Earth's crust, has the same mineral composition as basalt. At high temperatures, the mafic minerals cool and crystallize very quickly. As a result, some lava rocks have a thin layer of glass particles on their ...
