Mid-ocean ridges (MORs) are quintessential sites of tectonic extension1,2,3,4, at which divergence between lithospheric plates shapes abyssal hills that cover about two-thirds of the Earth’s surface5,6. Here we show that tectonic extension at the ridge axis can be partially undone by tectoni...
Street directories and a wide variety of atlases were some of their practical creations, whereas others analysed major planetary formations such as the mid-oceanic ridge, or lunar and extra-terrestrial maps to determine landing sites for space probes. Will C. van den Hoonaard, Map Worlds: a Hi...

The mid-ocean ridge system comprises a series of spreading ridges, transform faults, propagating ridges, and other non-transform offsets. Transform faults remain stable for millions of years leaving long linear scars, or fracture zones, on older seafloor. Propagating ridges migrate in the ridge par...
Imaging mid-ocean ridge transitions with satellite gravity Gravity maps derived from satellite altimeter measurements provide unprecedented me. Dium-resolution coverage of sparsely surveyed mid-ocean ridges in the ... C Small,DT Sandwell - 《Geology》 被引量: 2076发表: 1994年 Mid-Ocean Ridge Magma...
💡 Tip: PyGMT and GMT include built-in support for several different colormaps (called “CPTs” in GMT).⛰️ Isostatic stateThe first thing we’ll do is investigate the isostatic state of the mid-ocean ridges. In other words, are the ridges supported by their buoyancy (isostasy) or ...
Although they cover a narrower region than SCICEX maps (Cochran et al., in prep.) they have better resolution and navigation and they cover the western part of the ridge. Geological features can be interpreted more confidently than with SCICEX data. There is an abrupt change in ridge depth...
Maps were generated in GeoMapApp (http://www.geomapapp.org/) using the Global Multi-Resolution Topography synthesis base map [Ryan et al., 2009]. (a) The Mid-Atlantic ridge, (b) the Easter microplate and Salas y Gomez seamount chain, (c) the Galápagos spreading center, and (d) the ...
Detailed maps of bathymetry, free air gravity anomaly, and total field magnetic anomaly are presented for an area approximately 50×20mi along the crest of the ridge. The median valley and the associated belt of large positive magnetic anomalies are continuous and display a striking lineation in ...
