The lithification of loose sediment form sedimentary rock. Sedimentology is related to the basic sciences, which are biology, chemistry and physics. The fossils that deposited in the rocks are biological and weathering, diagenesis and formation of autochthonous sediments are about chemistry. The transportation and deposition of sediments are related to physics (Richard, 1988). Clastic rocks are the most common type of sedimentary rocks. Clastic rocks are composed of clasts or rock fragments which
average, CAA contributors have higher alkalinity capacities, and lower concentrations in barium. Coppermine, Thornsen, Kujjuua, and Cunningham CAA rivers actually match Mackenzie River in retrospect. These differences could be due to differences in sedimentology, geology, vegetative growth, surrounding wildlife and plant growth, as well as the flowing water sources. Most CAA contributors actually originate or are confined inside the Arctic Circle; this means most recurrent accretion is from snowfall or
indurated materials that form on the Earth’s surface (Selley 2000, 41). The study of sediment includes its provenance and the processes that result in their deposition of the weathered and eroded products of its older material. The purpose of sedimentology is to provide a deeper understanding about the Earth’s history. In a sediment, maturity is described as the degree of how much a sediment changed due to weathering, transport and reworked toward its ultimate end product, quartz sand (Nichols 2009
Brittany Simpsons Assignment #1 G135 Geology is the study of the Earth’s development, natural resources, and its history. Geology provides important ways of understanding Earth’s history through investigating the planet, soil, oceans, atmosphere, and many other methods of solving environmental problems. Like many sciences, geology has sub-disciplines that allow for the expertise in understanding specific aspects of the Earth’s development, history, and resources. According to the American Geosciences
Brimbank Park is located at north-west of Melbourne, which is about 30 minute drive from Melbourne CBD. As can be seen from the map (Figure 1), it is adjacent to the suburb of Keilor to the north, Kealba to the west. The landform pattern of Brimbank Park is alluvial landforms. Based on the map (Figure 1), Maribyrnong River is across the park. Therefore, the flowing water erodes, transports and deposits sediments, and erosional and depositional feature can be found from fluvial action.
Ichnology and the study of trace fossils is a valuable tool for unlocking the past biology of the planet, and giving information on behaviour, movement, and feeding patterns. The Mesozoic era, or the “Age of Dinosaurs”, ranged from 252-66 Ma and saw the world dominated by huge reptiles, some of which have been preserved in the fossil record. Over the years Australia has produced very informative dinosaur fossils, some of which are body fossils, but others being trace fossils, usually footprints.
Radioactive isotope dating techniques use present day processes as well as rates of processes to interpret past conditions and infer patterns of distribution and climate change and geology to past events. Techniques used to measure and reconstruct palaeoenvironmental records/frameworks depend on the material (proxy) that is preserved and the events that occurred when it became fossilized. There are radioactive properties in different materials, contained within them there are natural time signals
Using the results gathered from a recent field study at the The Leigh Brook, suggest the morphological, hydrological and sediment differences between the Pool and Riffle. Within a river there are areas known as pools and riffles. The pool is an area of deeper slow moving water, whereas the river is an area of shallow, fast flowing white water. The rocks are also clearly visible at the riffle, but submerged in the pool. A pool is usually found on a meander whereas the riffle is normally seen on
Chemistry is “the science that deals with the composition and properties of substances and various elementary forms of matter”. There are five branches of chemistry. There is organic chemistry, analytical chemistry, physical chemistry, inorganic chemistry, and biochemistry. We are affected by chemistry everyday. Whether it is the air we breathe or what is in soil, chemistry is everywhere. You can get various careers that involve the use of chemistry. You can be a forensic chemist, a geochemist,
