Composition of bottom sediments from the Campeche Bank
Listed in PANGAEA
A complete section of an unconsolidated sedimentary sequence about 5 m thick was sampled in the western margin of the Campeche Bank with use of gravity cores.
Description
The sequence forms a flat sea bottom at depth of 51-53 m and rests on a consolidated basement composed of coral limestones and carbonate sandstones. Initiation of deposition of unconsolidated sediments in this area is related to a sea transgression caused by sea level rise that followed the Würm glaciation stage about 10-11 ky ago.
Analysis of grain size and chemical compositions of sediments and study of biogenic carbonate remains made it possible to outline environmental changes in this region during the last 10 ky.
