Palaeozoic clay mineral sedimentation and diagenesis in
Associated clay minerals include smectite, locally preserved from diagenetic changes mainly by early pore closure, that reflect lagoonal or quiet offshore marine conditions Smectite and subordinate kaolinite abundances decrease upwards during the Devonian in three successive intervals suggesting alternations of subarid to drier climates2019 9 13 265, and is classified as a clay of high plasticity, CH via USCS (Unified Soil Classification System) 22 Experimental set up 221 Sedimentation To estimate and compare the coagulation efficiency of εpolylysine and chitosan, sedimentation tests of clay suspensions were conducted During the experiments, the temperature and relativepolylysine biopolymer for coagulation of clay suspensions2020 2 1 The differential settling of clay minerals is the result of the physical segregation of minerals during transport of particles in relationship to their different size and flocculation (Chamley, 1989) The distribution of clay minerals in sediments can be largely impacted by this processAuthigenic, volcanogenic, and detrital influences on the Sediment of the Bering Sea, derived mainly from biogenic, glaciomarine, and, secondarily, riverine sources, reflects the history of oceanographic changes within the basin and climatic changes on the adjacent continents Integrated Ocean Drilling Program (IODP) Expedition 323 recovered cores that reveal the evolution of sedimentation in the Bering Sea over the past 5 my, a period that Evolution of marine sedimentation in the Bering Sea since 2018 3 1 The smectiteillite transformation is the most important diagenesis for clay rocks It is generally agreed that the smectite reacts with the potassium feldspar to form the illite when the temperature is slightly higher than 60 °C, and the kaolinite reacts with the potash feldspar to form the illite when the temperature is higher than 100–120 °C, ( Bjørkum and Nadeau, 1998 )Advances in the origin of overpressures in sedimentary

Electrical impedance measurements are monitored during the sedimentation of a clay slurry and provide an insitu, noninvasive technique to study the sedimentation process1992 9 1 Conclusions From our mineralogical and geochemical in vestigations of the clay fractions from Japan Sea Cenozoic sediments (Sites 794, 795 and 797 of Leg ODP 127), we conclude that most of the clay sedimentation resulted in complex mixtures of detrital clays from two main origins: (1) smectite and/or chlorite of Japanese derivation with high E~d values (>33) and variable LREEen riched Clay sedimentation in the Japan Sea since the Early The performed studies demonstrated the transformation of sandbodies due to the nonuniform compressibility of clay and sand rocks, causing to the formation of various pseudostructural elements in the form of bends and foldsTransformation of sandbody geometry as the result of 2020 2 1 The differential settling of clay minerals is the result of the physical segregation of minerals during transport of particles in relationship to their different size and flocculation (Chamley, 1989) The distribution of clay minerals in sediments can be largely impacted by this processAuthigenic, volcanogenic, and detrital influences on cal sedimentation diameter [McCave 1991] Deviations from Stokes’ equation are expected when the particle are irregular in shape, as most silty particles, or platy or tubular as clay particles The particleshape effect is due to the circumstance that the most stable position of a settling nonspherical particleCOMPARING PARTICLE SIZE DISTRIBUTION ANALYSIS BY SEDIMENTATION
