Patterns of floodplain sediment deposition along the ... 2015-1-1 · Information from clay pads (feldspar markers) form the bulk of the results presented, used, and discussed in this paper. Artificial marker layers (clay pads) were placed at each sampling station. These markers are made by placing powdered white feldspar clay ~ 20 mm in thickness over an area of about 0.5 m 2 on the soil surface that has been ...Cited by: 25
Carbon, Nitrogen, and Phosphorus Accumulation in ... floodplain site 3-6 years prior to sampling. Sediment cores were collected from the material deposited over the feldspar clay pads. This overlying sediment was separated from the clay layer and then dried, weighed, and analyzed for its total carbon (C), nitrogen (N), and
CARBON, NITROGEN, AND PHOSPHORUS … 2005-8-1 · A network of feldspar clay marker horizons was placed on the sediment surface of each floodplain site 3–6 years prior to sampling. Sediment cores were collected from the material deposited over the feldspar clay pads. This overlying sediment was separated from the clay layer and then dried, weighed, and analyzed for its total carbon (C ...Cited by: 200
Spatial dynamics of overbank sedimentation in … 2008-8-15 · Feldspar clay marker horizons and marker poles were used to measure floodplain deposition from 2002 to 2005 and data were analyzed with geospatial statistics to determine the spatial dynamics of sedimentation within the floodplains.Cited by: 57
The effects of restored hydrologic connectivity on ... 2019-11-1 · A network of 15 to 27 feldspar clay artificial marker horizons (dimensions: 30 cm × 30 cm, 1 cm depth; Hupp and Bazemore, 1993) were installed at each site in April 2014 prior to scheduled floodplain restorations . Net vertical accretion of sediment above each marker horizon was measured pre-restoration in December 2014 (length of deployment ...Cited by: 8
Predominant floodplain over mountain weathering of ... 2012-5-1 · The increase in neo-formation of clay minerals during floodplain transfer is consistent with the change in D/H isotopic composition of the sediments even if a contribution of Chambal derived sediments must also be considered. 4.2.3.

Clay minerals in the stream floodplain soils in ... 2013-12-28 · An X-ray diffraction technique was used to study the composition of clay material from floodplain soddy- and mucky gley soils formed in the valleys of small streams in the reserve. The content of nonexpandable minerals was higher and the labile mineral content was lower in the fine fractions of the floodplain soils than in similar fractions of upland soils found in adjacent positions.Cited by: 2
Occurrence and pedogenesis of acid sulfate soils in ... 2021-1-1 · In profiles P2, P3 and P4, which are in the floodplain, the silt and sand fractions (fine and coarse) are composed of quartz and feldspar in all horizons, with mica in P2 . The clay fraction is composed of kaolinite, illite and smectite (Fig. 5, Fig. 6, Fig. 7 represent profiles P2, P3 and P4, respectively). The presence of quartz, feldspars ...

Soil Clay Mineralogical Phase Analysis of Ganges ... Soil minerals study is vital in terms of investigating the major soil forming compounds and to find out the fate of minor and trace elements in soils. It is also essential for the soil-plant interaction purpose. To identify soil mineral phases especially clay minerals, X-ray diffraction (XRD) has been a popular technique. The clay mineralogical information of soils in Bangladesh is limited ...Author: Shamiha Nazmin, Anindita Das, Md. Zulfikar Khan, Md. Sadiqul Amin, Md. Hanif
