A hydrous melting and fractionation model for mid-ocean ridge basalts: Application to the Mid-Atlantic Ridge near the Azores
[1] The major element, trace element, and isotopic composition of mid-ocean ridge basalt glasses affected by the Azores hotspot are strongly correlated with H2O content of the glass. Distinguishing the relative importance of source chemistry and potential temperature in ridge-hotspot interaction therefore requires a comprehensive model that accounts for the effect of H2O in the source on meltin...
متن کاملA near-bottom magnetic survey of the Mid-Atlantic Ridge axis at 26 N: Implications for the tectonic evolution of the TAG segment
[1] An extensive deep-tow magnetic survey of the TAG ridge segment on the MidAtlantic Ridge reveals new information about the relationship between the magnetic anomaly field and the TAG hydrothermal deposits. Results show the strongest magnetization is located over the neovolcanic axis and asymmetrically toward the western side of the central Brunhes anomaly. A well-defined linear magnetization...
متن کاملFeeding Ecology of Coryphaenoides rupestris from the Mid-Atlantic Ridge
The Macrourid fish roundnose grenadier, Coryphaenoides rupestris, is one of the most common benthopelagic fishes on the northern mid-Atlantic Ridge. The ecology of the species is comparatively well studied in continental slope waters of the North Atlantic, but not on the mid-Atlantic Ridge, which is a central mid-ocean area of its distribution. In total, 166 specimens from the RV G.O. Sars crui...
متن کاملPerformance of Mid-rise Buildings with Tubular Structure Under the Effect of Near Field Earthquakes
The aim objective of this study is to investigate the effects of near-field earthquakes on the response of mid-rise buildings with tubular structure. For this purpose, a 20-story building with a square plan of six by six bays, all with 6 m span, and story height of 3.70 m is considered. Axial force of columns, shear lag, and inter-story drift values are used as the main response parameters. N...
متن کاملLong-range backscatter from the Mid-Atlantic Ridge
Acoustic backscatter eturns measured with a vertical source and horizontal receiving array are beamformed and charted to respective scattering sites on the western flank of the Mid-Atlantic Ridge (MAR). Well-defined patterns of high-level backscatter esembling bottom morphology occur within the direct path and at convergence zone ranges. Measured backscatter is compared with modeled two-way tra...
