Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

The major magmatic volatile components—H2O, CO2, S, Cl, and F—play an important role
in the formation, evolution, and eruption of magma. Knowledge of magmatic concentrations …

Students of a phenomenon as common but complex as andesite genesis often are
overwhelmed by, or overlook, the volume and diversity of relevant information. Thus there is …

Pyroclastic Rocks is the first modern comprehensive treatment of what they are and how
they were formed. The subject is discussed against a background of plate tectonics theory …

At present the best estimates of the oxygen fugacity of spinel-lherzolites that could be the
source material of basic magmas is about five log units below the Ni− NiO buffer to one …

Convective circulation of seawater through oceanic crust at mid-ocean ridges (MOR) and on
ridge flanks has wide-ranging effects on heat transport, the chemical and isotopic …

Fresh submarine basalt glasses from Galapagos Ridge, FAMOUS area, Cayman Trough
and Kilauea east rift contain 22 to 160 ppm carbon and 0.3 to 2.8 ppm nitrogen, respectively …

Precise new analyses of ferrous and total iron for 78 hand-picked mid-ocean ridge basalt
(MORB) glasses constrain the redox states of MORB magmas, and the systematics of those …

The concentration of S in basaltic magmas at 1 atm pressure is strongly dependent on
temperature, the fugacities of oxygen (ƒ O 2) and sulfur (ƒ S 2), and bulk composition …

Major element, Sr isotope and trace element data for 16 elements are reported for various
weathered zones in three submarine basalt pillows. During the initial stages of alteration, it …
