Carolina bays are elliptical depressions concentrated along the Atlantic seaboard within coastal Delaware, Maryland, New York, New Jersey, North Carolina, South Carolina, ia, Georgia, and north Florida. In Maryland, they are called Maryland basins. Within the Delmarva Peninsula, they and other coastal ponds are also called Delmarva bays. They are named for the bay trees frequently found
#0183;#32;Abstract. The bottom sediments of Jinhae Bay area contain, on average, 45 % illite, 23 % kaolinite, 17 % intergrade clay, 10 % chlorite, and 5 % smectite. The geographical distribution of the clay minerals shows, in general, an it crease in illite, a decrease in kaolinite, and
By contrast, the clay mineralogy of the Orinoco River sediments (Figure 6) is dominated by illite (4347%) and kaolinite (27%). The very low smectite content (713%) is a characteristic feature of the Orinoco River [ Parra et al ., 1997 ; Pujos et al ., 1997 ].
Clay Mineralogy of Some Carolina Bay Sediments Kaolinite, a 14 A o clay mineral, and illite were identified in 23 samples collected from five Carolina Bays in southern North Carolina. The 14 A o clay mineral does not have the characteristics of any of the usual 14 A o clay minerals and can with some justification be called expanded illite, vermiculite, chlorite, or montmorillonite.
Tucson, Ariz. The first detailed examination of clay mineralogy in its original setting on Mars is offering new insights on the planets past habitability, research led by Planetary Science Institute Senior Scientist David T. Vaniman has found. The sedimentary rock samples tested were collected by NASAs Mars Science Laboratory rover Curiosity at Yellowknife Bay in Gale

Increase in kaolinite and montmorillonite with depth and corresponding decrease in illite is indicative of a Pleistocene pluvial period antedating Toka Clay time (14,000 to 22,000 years ). Lacustrine strata of postToka age, formed in a closed lake environment, consist of illite, illitemontmorillonite, montmorillonite, sepiolite with gypsum, sodium sulfate, glauconitic mica, and dolomite.
Studies of Recent marine sediments from the North Atlantic Ocean were made in order to understand better the effects of diagenesis on the clay minerals. Samples from the continental shelf, the continental slope and the floor of the northwestern basin, north of Bermuda, were made available through the courtesy of the Lamont Geological Observatory of Columbia University.
Some features of this site may not work without it. Geochemical characterization of the KrishnaGodavari and Manadi offshore basin (Bay of Bengal) sediments: A comparative study of provenance. Mazumdar, A.; The geochemical composition and clay mineralogy of sediments have been used to constrain the provenance.
Using clay mineralogy one can identify the source materials making up the Bay of Fundy. Conclusion The sediments of the Petitcodiac system is mostly fine grained with minerals transported from one source (the Bay of Fundy). Chemical alteration of some minerals took place during the transportation process. 4. Appendix for tables
Semiquantitative determinations of the claymineral composition have been made on nearly synoptic samples of surface suspended sediments collected seasonally throughout the San Francisco Bay system. The relative amounts of chlorite + kaolinite are generally highest in the northern reach of the system, whereas illite is dominant in the southern reach.
Clay Mineralogy of Some Carolina Bay Sediments | University of Georgia One of the intriguing aspects of the Carolina Bays is that they frequently overlap one another. Prouty reasoned that bays impinging on other bays were the result of multiple, serial, impacts with the last in the sequence retaining the common Carolina Bay form.

Fortytwo substrate sediment samples and three cores procured from the shelf region between Chennai and Cuddalore were analyzed to understand the spatial and vertical sediment distribution. Samples subjected to grain size, bulk and clay mineralogical analyses, REE and trace element geochemistry yielded interesting results about the sediment characteristics with respect to the modern day
The clay minerals in 23 samples of Carolina Bay sediments were identified by Xray diffraction methods in order to determine: (1) the clay minerals that characterize these bay sediments, and (2) whether or not the clay minerals were altered during or after deposition.

Renngarten, Geological Institute of the USSR Academy of Sciences, Moscow Thorough study of the mineralogy of clay matter retrieved from DSDP drill sites is important in understanding the geological development of the sea floor.
Surface samples from the eastern Barents and southwestern Kara seas have been analysed for clay mineralogy. Transport paths, the role of regional sources and local bedrock outcrops and the influence of hydrodynamic and glacigenous processes for clay distribution on the shelves are discussed in relation to central Arctic Ocean deep sea and sea ice sediments.

#0183;#32;Most previous studies of clay mineral assemblages in the ECS have focused on the surface sediments of estuarine areas and the Okinawa Trough over long periods (, the Holocene) to ensure the inclusivity of different sediment sources and partitioning processes during transport (Fan et al., 2001, Fang et al., 2007, Diekmann et al., 2008, Dou et al., 2010, Liu et al., 2014).
