During ODP Leg 167 within the California Current System sediments with variable siliciclastic proportions at thirteen drilling locations have been recovered. By combining results of the north-south transsect along the changing hinterland with known lithology with shelf-deep sea transsects, mineralogy ...

(3) An ultrastable heavy mineral assemblage of the Late Palaeozoic-Early Mesozoic mature, siliciclastic sediments, sourced mostly from reworked older internal siliciclastics, and from beyond the ANS, but which also incorporate detritus from extensive exposures of the ANS basement. They were affected ...
fundamentally the interplay of an evolving and complex plate tectonic setting, including development of a carbonate foredeep, changes in relative sea level within an overall transgressive regime, and changing availability, sources, and modes of deposition of both bioclastic and siliciclastic sediments. ...
Siliciclastic sediments must have advanced and retreated across the carbonate shelf with sea level rise and fall. DSDP Leg 9 cores and seismic profiles suggest that, periodically, portions of the west Florida and probably Yucatan margins have failed, injecting massive carbonate gravity d...
Banded iron-formation occurs in both basinal and platformal environments, indicating that deposition of these chemical sediments was perhaps independent of local variations in sedimentary tectonic setting. The preferred regional tectonic setting evokes shelf and basin sedimentation on a rifted passive contin...
