In transform convergent settings, most of the terrigenous sediment is trapped in the nearshore sedimentary basins, leaving the offshore basins to contain thinner layers of mostly biogenic sedimentation.
The low influx of terrigenous sediments helped in carbonate deposition in the form of Zaluch group (Mertmann, 2003).
The Upper Ordovician series (from Chertovskian to Burian regional stages) by contrast has been described as represented by a succession of cool-water carbonates dominated by bioclastic wackestone and packstone beds intercalated with fine-grained terrigenous sediments (Dronov et al.
A vast amount of terrigenous sediments is known to exist in the North Sea with an area of 100,000 [km.sup.2] [32].
His study focused on four types of sediments, namely, calcareous and siliceous oozes, pelagic clay, and terrigenous sediments. He then derived a regression function for each sediment type, but he emphasized that these density models should not be used for sediment depths greater than those indicated in his tables and figures (500 m for calcareous ooze, 250 m for radiolarian ooze, 300 m for pelagic clay, 500 m for diatomaceous ooze, and 1300 m for terrigenous sediments).
Since the majority of anthropogenic contaminants are derived from the mainland they may be used to track recent input of terrigenous sediments and to identify the main depocentres of recent sediments.
The exploration licenses cover areas that include occurrences of Lower Carboniferous Olonbulag terrigenous sediments that host coal seams.
This probing exercise demonstrated that the elongate rise was comprised solely of terrigenous sediments to a depth of 285 cm and the result of low-energy alluvial deposition.
The sites located off Galveston were typical of continental shelf and slope terrigenous sediments in the northwestern Gulf of Mexico.
