High-resolution images covering large areas of the seafloor reveal numerous discontinuities
along the mid-ocean ridge. These discontinuities occur at a range of scales (10–1,000 km) …

The crestal area of the mid-ocean ridge (MOR) is a stratigraphically complex and dynamic
environment where new lithosphere is created through intrusive and extrusive igneous …

A reflection observed on multi-channel seismic profiles along and across the East Pacific
Rise between 8° 50′ N and 13° 30′ N is interpreted to arise from the top of a crustal …

Using the near-bottom ARGO imaging system, we visually and acoustically surveyed the
narrow (< 200 m wide) axial zone of the fast-spreading East Pacific Rise (EPR) along 83 km …

Most of the structural patterns revealed by bathymetric and magnetic mapping of the oceanic
crust west and south of southern California and Baja California are inherited from the time of …

Lavas from the fast-spreading East Pacific Rise are geochemically diverse even within a
single tectonically defined spreading cell. Within such spreading cells, small offsets of the …

Morphological and structural data from the whole Tharsis province suggest that a number of
shallow grabens radially oriented about the Tharsis bulge on Mars are underlain by dykes …

Magnetic, bathymetric, and SeaMARC II side scan sonar data from the ridge flanks adjoining
the overlapping spreading center (OSC) at 9° 03′ N on the East Pacific Rise (EPR) are …

Studies of mid-ocean ridges in the Pacific and Atlantic oceans show that the volcanism that
forms the oceanic crust along the spreading-plate boundaries is concentrated at regular …
