ALTERATION AND DISSOLUTION OF FINE-GRAINED MAGNETITE AND ITS EFFECTS ON MAGNETIZATION OF THE OCEAN FLOOR

Weixin X.; der Voo R.V.; Peacor D.R.; Beaubouef R.T. (1997)

Scanning and transmission electron microscopy (STEM) of ocean-floor pillow basalts with ages between 0 and 70 Ma reveals progressive alteration of submicrometer titanomagnetite to phases such as goethite and clays. In ...
LARGE-SCALE LATERAL HEAT AND FLUID TRANSPORT IN THE SEAFLOOR: REVISITING THE WELL-MIXED AQUIFER MODEL

Rosenberg N.D.; Fisher A.T.; Stein J.S. (2000)

Large-scale, lateral fluid flow through oceanic crust provides an explanation for regionally low heat flow in several seafloor settings. A well-mixed aquifer (WMA) model provides a quantitative and conceptual tool for ...
SEAFLOOR SLOPES AT MID-OCEAN RIDGES FROM SUBMERSIBLE OBSERVATIONS AND IMPLICATIONS FOR INTERPRETING GEOLOGY FROM SEAFLOOR TOPOGRAPHY

Mitchell N.C.; Tivey M.A.; Gente P. (2000)

Observations from 145 submersible dives are used to create a database of mid-ocean ridge scarp topography and lithology. Seafloor lithologies are classified into extrusives, basaltic talus, dykes, gabbros and serpentinites, ...
