“…The rich sediment distribution in the PQ sector indicates that the sediments are transported Muttukadu and lower (0.5%) at Kovalam due to the effect of hydraulic on the sample population (Ergin et al 2007). In berm region, the percentage of heavy minerals was found to be low especially in Tiruvanmiyur (S.No.2 = 0.8%) and the maximum in Nainarkuppam (S.No.17 = 13.75%).…”

The present study was undertaken to examine the depositional and transportation pattern in the tourist beaches of Chennai in SE coast of India. Twenty four samples were analyzed for textural parameters, Linear discriminate function (LDF), C-M plots and heavy/light minerals from beach, berm and dune regions. Results of textural parameters indicate that they are coarse grained in the three regions. Majority of the samples indicate that they are moderately well sorted, symmetrically skewed and leptokurtic. The LDF analysis allowed in identifying areas that are characterized by: (1) beach, (2) shallow agitated environment and (3) fluvial deposits. C-M plots indicate that the sediments in the beaches were deposited from the near shore environment. Heavy mineral analysis suggests that the heavy and light minerals were in the range of 0.5 to 16.9% and 82.08 to 98.14% and the light/dark layers are controlled by the prevailing tidal conditions in the coastal region. It is observed that sand is accumulating from the shallow agitated environment, while the transportation and deposition of sediments is mainly due to the interaction of tidal activities at the same time. C-M plots suggest that the sediments fall in the graded suspension and the saltation activities in the region also facilitate to understand the hydrodynamics of the region suggesting that they are deposited by high-energy activities.

“…The heavy minerals are resistant to mechanical and chemical alteration processes; consequently, they are useful as natural tracers, so much for their hydrodynamic behaviour and their potential of preservation (Morton, 1985). The concentration and distribution of heavy minerals in LN sediments is mainly controlled by the rate and the source type of sediment supply, the hydraulic processes, as well as by the grain size and the specific weight (Ergin et al, 2007). Another factor controlling the distribution of the heavy mineral content is their mode of erosion, transport and sedimentation, due to their selective resistance to weathering and hydrodynamic processes (Frihy and Dewidar, 2003).…”

The present study gives a trial to enhancement the management of Lake Nasser (LN) sediments and presents a demonstration of the sediments assessment process through focusing mainly on the sedimentological, minerlogical and radiometric characteristics of LN and the adjacent beach sediments. The study revealed that the increasing of sediments accumulation rate at LN cause many challenges and problems which change the morphological features and formation of the flood plains and inner islands. The occurrence of sediment accumulations and heavy mineral placers in LN onshore sediments is known but no systematic attempts has so far been made to management and explore these heavy minerals. The detailed mineralogical and γ-spectrometric studies for Lake Nasser sediments revealed that the grain size distribution in bottom samples dominant by sandy-silty clay in contrast of silty clayey sand and clayey silty sand in the eastern and western banks, respectively. Heavy fraction in the bottom sediments of LN and the adjacent beach indicates relatively low concentrations of the economic heavy minerals (magnetite, hematite, ilmenite, leucoxene, rutile, zircon, garnet and monazite) that varies between 0.61% and 1.22% for LN offshore sediments and ranged between 1.40% and 1.73% for the eastern beach samples where the western beach samples record 1.30% and 1.73%. It follows that their industrial exploitation is not economically profitable, in spite of previous exploratory studies in the survey zone. The radiometric analysis of all samples showed weak level of radioactivity. Lake Nasser bottom samples showed higher radiometric measurement relative to the adjacent beach samples. This may be attributed to the occurrence of monazite in the LN fine sediments that reach up to 0.0039% and also the presence of some metamict zircon. The proposed solution for lake sedimentation problems is to prevent eroded particles from entering the lake in the first place by mechanical dredgers. Utilization of economic minerals occurrence in LN can be facilitated by dredging mud into the lake banks. The mud fertility of the reclaimed landin the area. This process also stops sand dunes progression especially in the western bank. tween lat. 21.8 and 24.0° N and Long. 31.3 and 33.1°E, covering area of about 6,600 Km 2 with total storage of about 162 billion m 3 at water level 182 m (Avakyan and Iakovleva, 1998).

“…Terrigenous material makes up a considerable proportion of total sediment accumulation in the Southern Ocean, grain size and heavy mineral composition provide important signals of the sediment origin (Ehrmann & Polozek 1999, Diekmann 2007, Ergin et al . 2007, Hauptvogel & Passchier 2012). Grain size is sensitive to environmental changes and has long been used to identify types of depositional environments (Gao & Collins 2001).…”

Characteristics of heavy minerals and grain size of surface sediments on the continental shelf of Prydz Bay: implications for sediment provenance

et al. 2015

Data on grain size and heavy mineral composition for surface sediments on the Prydz Bay continental shelf was analysed to identify sediment features and provenance. The grain size composition of surface sediments indicate spatial variations in the glaciomarine environment and the key factors influencing sedimentation, which on the shelf include topography/water depth, currents and icebergs. The study area was divided into two sections by Q-type factor analysis: section I included Prydz Channel, Amery Basin and Svenner Channel, and section II included Four Ladies Bank, Fram Bank and the area in front of the Amery Ice Shelf. Sedimentation in section I is mainly controlled by currents and topography/water depth. However, in section II, icebergs/floating ice masses, the Amery Ice Shelf and currents have prominent effects on sedimentation. The heavy mineral composition indicates that surface sediments on the eastern side of the bay, including Four Ladies Bank, are primarily derived from Princess Elizabeth Land. Sediments in the area in front of the Amery Ice Shelf, Svenner Channel, Amery Basin and Prydz Channel have a mixed source from the eastern regions around the bay, including the Prince Charles Mountains and Princess Elizabeth Land. The contribution from Mac. Robertson Land to sediment at Fram Bank is limited.
