Clastic Sedimentary Rocks Clastic sedimentary rocks are classified according to the grain size of the sediment and the kinds of rock fragments that make up the sediment (Table ). Grain size is largely a function of the distance the particle was transported.
The Tectonics and Geochronology group specializes in geochronology, thermochronology, geochemistry, petrology, GIS applications, and structural geology. Research projects currently span the globe, including Albania, Brazil, Colombia, Iran, Italy, Tibet, Turkey, and the central and western United States.
Major orogenies border these cratons due to collisions during the formation of Gondwana, (and subsequently Pangaea), and during this time large sedimentary basins formed across the plate (Taylor et al., 2009). Placer deposits, such as the gold of the Witwatersrand in South Africa, were then able to accumulate in these basins.
Sedimentation and Tectonics in Rift Basins: Red Sea Gulf of Aden presents new case studies and synthesises the results of recent research on the sedimentological evolution of the Red Sea .
TECTONIC FORCE (Ft) – It results from two plates converging/colliding one against the other. The convergence is responsible for large compressional forces that break the crust into large blocks bounded by thrust faults, which progressively pile up to build the mountain range. We will call this a positive force, as it favors the building process.

The Accommodation Space Equation. Over long time scales (105–108 years), sediment accumulation is controlled by changes in eustatic sea level, tectonic subsidence, and climatic effects on the production of sediment. Some of these terms are often confused, so it is best to start by defining each of them.

On some Great Basin desert piedmonts, sedimentation was caused by peak aridity during the Holocene; although this secondary fan aggradation was often a result of fanhead entrenchment rather than increased primary sediment delivery from basin hillslopes (Harvey et al., 1999; Ritter et al., 2000).
c) Orogenic belts the currently or formerly active edge of continents, severely deformed due to earth movements (orogenic = "mountainbuilding"). d) Passive margins the trailing edge of continents; little or no tectonic activity. Craton: The North American craton is exposed mainly in the Canadian Shield.
The plate tectonics paradigm shift. Geosynclinal theory. Early sedimentary geologists identified the presence of thick sedimentary sequences on the continental craton, much of which appeared marine in origin. Most models invoked vague notions of uplift, subsidence, compression and .
Sedimentation Analysis. an aggregate of methods for determining the size of particles in dispersed systems by establishing the sedimentation rate and the parameters of the sedimentationdiffusion or sedimentation equilibrium. Sedimentation analysis makes it possible to determine both the average characteristics of the dispersion and...

Plate Tectonics. The motions of the plates have a tremendous ability to shape and deform rocks through a variety of processes that include folding, faulting, extension, and, on a massive scale, mountain building . New crust is constantly being created at rifts zones, or midocean ridges where lava cools as new rock.

Sedimentology and Sedimentary Basins : From Turbulence to Tectonics, Paperback by Leeder, Mike, ISBN, ISBN13, Brand New, Free shipping in the US "The sedimentary record on Earth stretches back more than billion years and is present in more abbreviated forms on companion planets of the Solar System, like Mars and Venus, and doubtless elsewhere"
The subsidence can result from a variety of causes that include: the thinning of underlying crust, sedimentary, volcanic, and tectonic loading, and changes in the thickness or density of adjacent lithosphere. Sedimentary basins occur in diverse geological settings .
The Process of Rock Cycle. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock. However, the process takes thousands to millions of years. The process begins when rocks thrust upwards by .

Late Early Miocene to Middle Miocene Clastic Sedimentation. The Kinabalu emplacement (108 Ma) event plausibly contributed to uplift and supply of sediments. This was followed by development of the Baram Delta which prograded to NW Sabah, and Kinabatangan Delta prograded to NE Sabah (Figure 7).
