Linking Time and Space in Geology: The Sedimentary Processes of Transgression and Regression. In geology, space and time are inexorably linked (Kastens & Manduca, 2012; Manduca & Kastens, 2012). The relationship of rock layers vertically and laterally is indicative of large-scale changes in the environment.Fine-grained rocks include mudstone, shale, siltstone, and claystone. Mudstone is a general term for rocks made of sediment grains smaller than sand (less than 2 mm). Rocks that are fissile, meaning they separate into thin sheets, are called shale. Rocks exclusively composed of silt or clay sediment, are called siltstone or claystone ... Aeolian, sometimes spelled eolian or œolian, are deposits of windblown sediments. Since wind has a much lower carrying capacity than water, aeolian deposits typically consist of clast sizes from fine dust to sand [ 52 ]. Fine silt and clay can cross very long distances, even entire oceans suspended in the air.Shale, siltstone, sandstone, and conglomerate are all types of sedimentary rock.
