New discriminant-function-based multidimensional discrimination of mid-ocean ridge and oceanic plateau

Mid-ocean Ridge Tectonics, Volcanism and Geomorphology

Figure 11 Average depth of magma lens reflections beneath ridges versus spreading rate. The curved line shows the depth to the 12003C isotherm calculated from the ridge thermal model of Phipps Morgan J and Chen YJ (1993) Journal of Geophysical Research 98: 6283}6297. Data from different ridges are labeled Reykjanes Ridge (RR), Juan de Fuca Ridge (JdF), Costa Rica Rift (CRR), Lau Basin (Lau), no...

Magmatic filtering of mantle compositions at mid-ocean-ridge volcanoes

Earth’s dominant form of magmatism occurs at mid-ocean ridges (MORs), producing the igneous crust for two-thirds of the planet’s surface and conveying significant heat and material fluxes from the mantle to the world’s oceans. Mid-ocean-ridge basalt (MORB) magmas form from upwelling compositionally heterogeneous mantle1 by aggregation of near-fractional melts beneath spreading centres2. Multipl...

Seismotectonics of mid-ocean ridge propagation in Hess Deep.

Hydroacoustic data from the eastern equatorial Pacific reveal low-magnitude seismicity concentrated at the propagating tip of the Galapagos Rise in Hess Deep. The patterns of seismicity and faulting are similar to those observed in the process zone of laboratory-scale propagating tensile cracks. Because the fracture energy required for propagation scales with crack length and process zone size,...

High-Resolution 3D Simulations of Mid-ocean Ridge Hydrothermal Systems

Discriminant Function Analysis Based on Principal Components for Rapid Discrimination of Metabolic Capabilities of New Isolates

The growing need for new microorganisms with novel metabolic capabilities has urged scientists to search for life in extreme environments. With the rapid progress in experimental methods, it is possible to isolate new microorganisms at high speeds but the bottleneck in this process is the biochemical characterization due to time and financial limitations. Inferential hierarchical clustering of ...
