“…The moderately well-sorted sediments suggest low and reasonably high energy current (Friedman, 1962;Blott and Pye, 2001). These values show that the sediments derived from the river channel are transported from various sources (Layade et al, 2019). The kurtosis lowest value shows very leptokurtic to extremely leptokurtic nature.…”

“…The kurtosis lowest value shows very leptokurtic to extremely leptokurtic nature. These values suggest the high energy depositional environment (Friedman, 1962) and also implies that the central portions are better sorted at the tails and suggests that the samples are located at the water concentrated zone (Layade et al, 2019).…”

Size, shape, degree of sorting, and composition of sediments in the river channels are controlled by climate, lithology, weathering, sorting, and medium of transportation. The present investigation is focused on the grain-size and geochemical analysis of the channel sediments of the Orsang and Hiren river basins. Major outcrops in the study area are Archaean granites, granitic gneisses, Upper Cretaceous to lower Eocene Deccan Volcanic Basalts (DVB), Quaternary sediments and minor proportion of Proterozoic low grade metamorphic rocks. The sediments are poorly to moderately sorted, very finely skewed, suggesting its derivation from heterogenous sources, while the kurtosis value indicates a high-energy depositional environment. The sediments are with gravelly sand texture and the mean grain size is varying from 581.9µm to 1284.2µm. The DVB provenance of the Hiren river basin and granitic provenance of the Orsang river basin is clearly reflected in the texture and geochemical composition of sediments. The TiO2 and Fe2O3 contents of sediments from the Hiren river basin are distinctly higher and are comparable to the basalts of the Saurashtra region of the Deccan Province. Sediments collected after Orsang and Hiren rivers confluence and from Narmada river show higher concentration of felsic sources, indicating that Orsang river's sediment supply significantly outweighs Hiren rivers. The arkosic-litharenite nature points towards less transportation and moderate chemical weathering for the Orsang river sediments. The low Chemical Index of Alteration (CIA) values (Avg. 48.45 and 56.99 for Orsang and Hiren rivers, respectively) and A-CN-K plot also suggest the supply of sediments from minimally weathered detritus under a semi-arid condition.

“…Friedman (1967) recommended that extreme high or low values of kurtosis signify that part of the sediment achieved its sorting in a different place in a high energy environment. The variation in the kurtosis values is a reflection of the flow characteristics of the depositing medium (Seralathan and Padmalal, 1994;Baruah et al, 1997).…”

Stream sediments were collected from different areas in Ifelodun county within latitude 8°451N to 8°51N and longitude 4°461E to 5°61E. 13 samples of sediments were obtained from each of the eight locations totaling 108. A German standard sieve set of mesh with shaker was used for grain size analysis. The results of grain size analysis range from medium to very coarse sand as the majority of sediment composition before investigation of textural parameters. The result of textural parameters was obtained and used to differentiate the depositional environment of the sediments. The mean, sorting, skewness and kurtosis defined the sediment as very coarse, poorly sorted, vary from very fine skewed to near symmetrical with mesokurtic environment, although the other extreme tails also exist. Positively skewed and poorly sorted sediments characterized low energy environment.

“…The particle size parameter is an absolute value for expressing the particle size characteristics of debris material. Commonly used particle size parameters include the average particle size, standard deviation, kurtosis, skewness, and fractal dimension [18][19][20][21] . In this paper, we use the graphical method proposed by Folk and Ward 22 to calculate the particle size parameters.…”

The material basis for soil formation is rock weathering debris. Understanding the particle size composition characteristics of rock weathering debris and its impacts is important for improving the soil structure of dry farmland in the central dry zone of Ningxia,China. In this study, the particle sizes of weathered debris collected from grey–green slate after indoor simulations of freeze–thaw and dry–wet cycles tests were examined. The results were as follows: (1) Under 16 treatments, the weathering debris of grey–green slate contained about 10% or less very fine sand and coarse silt, while clay, fine silt, and fine sand were the most abundant sizes (at least 60% of the total). (2) Under each treatment, the average particle size of the grey–green slate weathered debris was 5.52Ф (silt grade). The overall skewness was high, but the symmetry was poor. The particle size frequency distribution curve had many broad peaks or multiple peaks. (3) The fractal dimension was associated with very fine silt but had a strong negative correlation with fine sand and medium-coarse sand. The results indicate that fractal dimension can reflect the grain size characteristics of weathered debris. The mineral element content of the grey–green slate somewhat affected the fractal dimension, and it positively correlated with environmental electrical conductivity (EC) and element-leaching amount; it negatively correlated with particle size, temperature, and pH. According to the findings, the fractal dimension can accurately represent the particle size distribution of weathered debris. The generation of grey–green slate weathering debris should be considered in the formation and development of local soil.
