    During , ocean sediments off Point Loma were composed predominantly of very fine sand and coarse silt with a mean particle size of mm or phi (Table ). Fine sediments (silt and clay fractions combined) averaged about 37% of the sediments overall, while sands accounted for 60%. Coarser materials such as shell hash and. We applied cosmogenic 26Al/10Be burial dating to sedimentary deposits of the ancestral Colorado River. We compared cosmogenic burial ages of sediments to the age of an independently well-dated overlying basalt flow at one site, and also applied cosmogenic burial dating to sediments with less precise independent age constraints. All dated gravels yielded old ages that suggest several episodes.

Late Pleistocene equatorial Pacific sediments can be correlated by the ratios of certain solution-susceptible versus solution-resistant planktonic foraminifera. These ratios fluctuate in a cyclic manner whose timing is in phase with glacial-interglacial fluctuations established by Cited by:

ANALYSIS OF WET-BULK DENSITY AND SEDIMENT COLOR CYCLES IN PLIOCENE-PLEISTOCENE SEDIMENTS OF THE OWEN RIDGE (SITE ) AND OMAN MARGIN (SITE )1 William H. Busch2 ABSTRACT. Deep Sea Drilling Program (DSDP) Site ( N, E, m water depth, DSDP Leg 24) is the closest Plio-Pleistocene marine sedimentary record to the East African Rift System.

The core site is located in the central Gulf of Aden, south of the central spreading rift axis ridge, at – km from East African volcanoes and within. Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles.

For example, sand and silt can be carried in suspension in river water and on reaching the sea bed deposited by buried, they may eventually become.ments (Pleistocene and Holocene),2一Sediments of upper Pleistocene marine terraces, 3一middle to upper Pliocene and lower Pleistocene sediments, 4一 Tortonian to lower Pliocene sediments, 5一Basement rocks, 6一Main faults (small triangles on downthrown sides), 7一Possible faults.
