Comparative mineralogical and geochemical clay
The mineralogy and geochemistry of the bulk rock and clay fraction of sediments deposited at the CretaceousTertiary transition and in the KTB layer have been investigated by various methods in two sections from the Betic Cordilleras (Agost, Caravaca) and five sections from the BasqueCantabrian Basin (monte Urko, Sopelana, Zumaya, Hendaye, Biarritz)Geochemical and isotopic approaches to constraining provenance of sedimentary rocks complement the information inferred from petrography Geochemical approaches have several advantages, including applicability to both matrixrich sandstones and shales and ability to constrain provenance age and geochemical historyGeochemical approaches to sedimentation, provenance, Geochemical analysis shows that the clay mineral assemblages in the Cleveland and Wessex Basins are similar; kaolinite and illite are the main minerals in both basins [5,13,75] The clay minerals are likely to be the product of weathering and erosion of subaerially exposed siliciclastic rocks Minerals Free FullText Sedimentation of the Geochemical analyses of sediments from the top 245 m of Deep Sea Drilling Project hole 596 (23°5120′S, 169°3927′W) show great variability in the composition of pelagic clays accumulated in the South Pacific since the late Cretaceous Elemental associations indicate that most of this variability can be attributed to variations in abundances of Sedimentation history of the South Pacific pelagic clay This thesis presents independent climate modelling, sedimentological, and geochemical datasets from three timeequivalent sections, spanning 1 million years, in the northern and southern extents of the Laurasian Seaway (30–60°N palaeolatitude) in order to investigate climate dynamics and controls on sedimentation at different northern hemisphere latitudes in the Late JurassicLate Jurassic Sedimentation in the BorealTethyan Seaway:

Clay Sedimentology is a comprehensive textbook divided into six parts: clay minerals and weathering clay sedimentation on land origin and behaviour of clay minerals and associated minerals in transitional environments (estuaries, deltas) and shallowsea environments diverse origins of clay in the marine environment postsedimentary processes intervening during early and late diagenesis use of clay Such geochemical condition changes affected the sedimentation rate: during this time, at about 9800 cal y BP, the sedimentation rate reached 15 mm/y In the upper part of the column (at about 252 cm, 850 cal y BP), there was another peak of carbonates where the concentration of CaO changed from 3% to 20%Geochemical Approach to the Reconstruction of This thesis presents independent climate modelling, sedimentological, and geochemical datasets from three timeequivalent sections, spanning 1 million years, in the northern and southern extents of the Laurasian Seaway (30–60°N palaeolatitude) in order to investigate climate dynamics and controls on sedimentation at different northern hemisphere latitudes in the Late JurassicLate Jurassic Sedimentation in the BorealTethyan 2007 5 8 Late Albian (earlyoceanic) The remarkable geochemical feature of this stage is that the major part of the main components and heavy metals accumulated as basaltic volcaniclastics and clay products of their alteration The volcaniclastic material is closely bound to sapropelic organic matter Shallowwater carbonate turbidite sediments play a geo38 GEOCHEMICAL HISTORY OF POSTJURASSIC SEDIMENTATION IN THE CENTRAL 1A condensed interval with sedimentation rates of ca 20 cm/ky occurs from the Early Holocene until ca 64 ka; sedimentation rates increase after that to between 60 and 190 cm/ky A major break in preservation is also inferred at Indus‐23 where most of the Middle Holocene is missing ( Figures 2d and 4 )Geochemical record of Holocene to Recent
