Change in the Chemical Composition of Sediments in Contact Zones with Basalt Sills, Guaymas Basin, Gulf of California (DSDP 478 borehole)

Change in the Chemical Composition of Sediments in Contact Zones with Basalt Sills, Guaymas Basin, Gulf of California (DSDP 478 borehole)

The example of the Guaymas Basin in the Gulf of California (DSDP 478 borehole) shows the change in the chemical composition of the Upper Pleistocene sediments in specific short-term hydrothermal systems that arise when basalt sills intrude into nonlithified cold highly porous sediments with sea wate...

Zusammenfassung:The example of the Guaymas Basin in the Gulf of California (DSDP 478 borehole) shows the change in the chemical composition of the Upper Pleistocene sediments in specific short-term hydrothermal systems that arise when basalt sills intrude into nonlithified cold highly porous sediments with sea water. Changes in the chemical composition of the sediments (turbidites interbedded with hemipelagic sediments) in contact zones with basalt sills in Guaymas Basin in the Gulf of California are studied by X-ray fluorescence (XRF) analysis and inductively coupled plasma mass spectrometry (ICP-MS).
