“…An indicator of the fluvial environment is the positive skewness (Kasim et al 2023). The sediments' positive skewness, or very fine-skewed character, indicates the process by which small particles are naturally separated from coarser debris by moving water (Aigbadon et al 2022). The distribution of grains in a finely skewed sediment population will be from coarse to fine, with the frequency curve chopping at the coarser end and tailing at the finer.…”

Erosion poses a significant challenge along the river Subansiri in Assam, India impacting river banks and sediment breakdown. This paper presents a comprehensive study on the identification of soil erosion-susceptible areas in the Subansiri Basin using fuzzy logic modeling and sediment transport index (STI) analysis with emphasis on X-Ray Diffraction (XRD) and grain size analysis. The soil erosion map's overall findings showed that the areas it covered were vulnerable to erosion in severe, very high, high, moderate, and low levels. Slope gradients and flow accumulation were used to calculate the STI on the Raster Calculator in ArcGIS. The Sediment Transport Index ranges from 0 to 2770. This study also aims to elucidate the mineral composition and grain size distributions of sediments sourced from the Subansiri river in Assam. Examination of 12 soil samples facilitated the assessment of their mineral composition and size distribution. Sieve analysis unveiled that a predominant 80% of the soil along the Subansiri river constitutes sand, with lesser percentages attributed to silt and clay, following USDA primary classification guidelines. Utilizing XRD methodology, the major crystalline minerals identified in these sands encompassed Quartz, Montmorillonite, Illite, Calcite, and Plagioclase Feldspar Albite. Skewness and kurtosis is also studied to determine the shape and distribution of the soil samples and the values range from 0.25 to 0.70 signifying a fine skewed to very fine skewed and from − 1.16 to -1.93 showing a very platykurtic distribution. Thus, for a thorough investigation of soil erosion, this research provides a novel hybrid methodology that integrates fuzzy logic, STI, XRD and grain size analysis.

“…In recent years, Chinese scholars have made important progress in the sequence-stratigraphy evaluation of lacustrine basins [11][12][13][14][15]. The study of sequence stratigraphy can help to establish an isochronous-sequence stratigraphic framework, and the study of sedimentary characteristics and evolution law under its control is conducive to defining the distribution characteristics of sand bodies [16][17][18]. All these studies can guide the detailed exploration of complex lacustrine basins.…”

The sedimentary characteristics of the Neogene in the eastern Liaodong area are poorly studied, which restricts the oil and gas exploration in this area. Based on the current seismic, logging, drilling, and core data, we have studied the sequence stratigraphy and sedimentary characteristics of the Neogene in the eastern Liaodong area. Ultimately, we identified the controlling factors of sedimentation and established the depositional model. In this study, six sequence boundaries of the Neogene were identified and can be divided into five third-order sequences. The sedimentary evolution can be divided into four stages: braided river delta, meandering river delta with a low sand-stratum ratio, meandering river delta with a high sand-stratum ratio, and meandering river delta. Both the palaeotectonic movements and paleoclimate changes of the Neogene influence the periodical fluctuation of the lake level and then control the vertical evolution of the sedimentary types. The paleogeomorphology controls the macroscopic distribution of the sedimentary facies zone, the paleo-valleys that are associated with the strike-slip faults control the channel strike, and the fault slopes at the edge of the lacustrine basins control the sand redistribution of the delta front.
