Recent organic-rich deposits on the Peru continental margin
occur along the upper slope (100-450 m) between about ll°S and 16°S
and along the lower continental slope (>2000 m). The upper slope
deposits reflect high biological production in response to coastal
upwelling, but preservation of organic matter is enhanced by the...
Seep characteristics at different geologic settings are the subject of this review primarily based on results of the Research Consortium SFB 574. Criteria are drawn from examples on the erosive convergent margin off Costa Rica, the accretionary margin off Chile supplemented by examples from the transform margin of the Golf...
Hydrate Ridge has the distinction of hosting the first documented subduction-driven cold seep system that supports chemosynthetic life by Anaerobic Oxidation of Methane as well as the most widely researched methane hydrate setting at any active continental margin. Today this site is a vital node of Northeast Pacific regional long-term...
The Blanco Trough, a deep depression located in the Blanco Fracture Zone near the intersection with the Juan de Fuca Ridge, contains unusual manganese-enriched layered sediments. Due to the Blanco Trough's bathymetric isolation and confinement, and its location in a tectonically active zone, three hypotheses concerning the origin and cause...
Sedimentation rate could become a new exploration tool for evaluating
the source rock potential of sedimentary basins in frontier regions.
Petroleum source rocks are defined on the basis of total organic carbon
by weight percent. An analysis of Deep Sea Drilling Project (DSDP)
cores indicates that there exists quantitative relationships...
