What Is The Construction Of The Triple System

The Repton Long Barrow sits between the parish church and the River Esk in Repton, Bluffshire, U.K. Last summer, I examined evidence for previous disturbance(s) of the site and assessed the extent to which the original Neolithic burial mound remained intact. I excavated two different sites on the mound, one on the east end and another on the west end of the barrow. While excavating and cleaning each of the sections, I recovered artifacts and human bones. I was also able to draw a stratigraphic profile of each excavation site. Using documentary sources pertaining to the Repton Long Barrow site to assist in my interpretation of the history, I was able to reconstruct the

It can be argued by some geologists that significantly more time is lost at bedding planes than is recorded by the accumulation of sediment and its later lithification into a sedimentary rock. In the present paper, the continuity of the sedimentary record is investigated. It is hypothesized that sedimentary strata preserved predominately records episodic sedimentation events and gaps represented by bedding planes symbolize more time than the preserved strata. The incompleteness of the geologic record and the role of rare events was studied using data gathered from a variety of sedimentary outcrops and cores. The author addressed his hypothesis using this collected data in terms of sediment preservation and represented preservation as a function of two modes of geomorphic processes: Magnitude and frequency. The author tested his hypothesis using relatively modern storm events to represent sedimentation, showing how daily processes can distort the geologic record, and by using ancient examples to illustrate how some storms can be preserved in spectacular condition.

Scientific discoveries indicate to us that the sites major construction first began in approximately 3000 BC. Neolithic builders are believed to have laboured for 1500 years. We now know that the Stonehenge was built in three stages [23 & 24]:

The Glasshouse Mountains are volcanic plugs that were originally surrounded by sandstone (MSCR, 2012). The plugs are formed of material that is more resistant to erosion than the sandstone that once surrounded it, and the plugs were revealed when the softer rock eroded away (Tourism Australia, 2015). The weathering of the sandstone is evidence to support the existence of

This investigation will be exploring whether the movement of pebbles, shingle, shells and other materials found on the beach have impacted on the shape and structure of Newhaven beach and Castlehead Cliff. One of the key processes this investigation will focus on is that of long shore drift caused by strong prevailing winds, prevailing wind is the direction from which the wind usually blows. Cliffs are made from mainly two materials, chalk which is at the bottom and sand and clay at the top. If cliffs are facing the direction of prevailing wind it may lead in high rates of cliff

The Year 10 geography field trip was an insightful experience into the workings and functioning of metropolitan coastlines here in South Australia. The day consisted of visiting various beaches in Adelaide that were influenced by some form of hard or soft engineering techniques that changed the natural processes of the beaches. What was evident from this trip was how much these beaches have been changed to an extent where it is unlikely that they will ever go back to the way they were prior to human settlement.

Kangaroo Point Cliffs are one of the most iconic places that highlight Brisbane city’s history along with the Brisbane City Hall and Story Bridge. These cliffs were known by Aborigines even before European settlers arrived in Brisbane. The development around the Kangaroo Point Cliff was started in the 1900s when roads were developed around the cliff. Today, the Kangaroo Point Cliff offers many adventurous activities such as rock climbing, kayaking on the Brisbane River, Segway tours, bike riding around the garden etc. The rocks found on these steep cliffs are known as the ‘Brisbane Tuff’. These unique pink and green stones were also used in building public buildings during the 1820s and 1830s. The very steep feature and gas holes on the cliff plays a significant role in identifying these cliffs a result of a volcanic eruption (Visit Brisbane, 2018). This essay analyses geological formation of Kangaroo Point cliff and the Brisbane tuff which the

Mesa Verde National Park on the Colorado Plateau contains many geological aspects of interest, including its sedimentary rock layers, its canyons, its alcoves utilized by ancient people and how these alcoves were formed. Mesa Verde National Park is located in the southwest corner of Colorado, close to the Four Corners area, on top of a high mesa overlooking the Mancos River (Harris et al. 2004). The park, covering 81 square miles, consists of several main sedimentary formations that are characteristic to the park (Encyclopedia Britannica 2015). Canyons are carved into the sedimentary rock, with the cave dwellings found high on their steep walls. These dwellings are an especially unique aspect to the Mesa Verde National Park, and are built out of large alcoves. The alcoves were produced by weathering and erosion of the sedimentary rock type. To better understand how these alcoves formed, we must understand the geology of Mesa Verde National Park and how it has developed over history.

The inside structure obliged a sum of 68 tons of 30m long, 1500mm measurement fortifying pens. These heaps are socketed 2m into the bedrock underneath the Brisbane River. The pre-assembled strengthening pens must be built to tight resistances to guarantee the site lapping of the enclosures continued easily and productively.

The base of IIIb1 appears slightly oxidized and yielded an age of 2277± 36 14C yr BP. Above this is a ~60-cm-thick, organic-rich “black mat” (IIIb2) consisting of multiple thin beds containing varying amounts of plant matter including both decomposed humic material and uncharred plant macrofossils that constitute a significant proportion of the sediment volume in the most organic-rich deposits. The IIIb2 black mat was formed between 1934 ± 29 14C yr BP and 1759 ± 25 14C yr BP, with the most organic-rich portion predating 1833 ± 36 14C yr BP. Organic carbon content of the black mat varies, but the highest values are ~2%. Plant remains in IIIb2, consisting mostly of bulrush achenes and pollen, indicate emergent aquatic floodplain vegetation, and the unidentifiable stem fragments ubiquitous throughout the layer are likely also bulrush (Figure 8). Faunal remains within IIIb2 at 11-37 include snail and ostracode species indicative of marshy conditions (Table 4). From the base of IIIb1 to the sharp upper boundary of the IIIb2 black mat, a trend of decreasing calcium carbonate, increasing gypsum, and increasing organic carbon is evident. Gypsum content ranged from 3.7–16.6% and occurred as tiny clumps of intergrown lathe crystals, whereas carbonate content ranged from ~4–13% and occurred as small soft

The oldest part of Stonehenge, called Stonehenge I (constructed ca. 3100 BCE), consists of little more than a circular ditch dug in the soil of the Salisbury plain, with the excess soil piled up to make an embankment approximately six feet tall. This area is approximately three hundred thirty feet in diameter, and encompasses “Stonehenge proper” – the familiar circles of massive stones that once stood

Ralph Allen Yard (located in the eastern section of Combe Down) is an area that malting’s and industrial activity had been prominent to certain extent. However, over several decades, the yard itself has been subjected to continuous alteration leading to structural deterioration and redundancy to its use. The historic significance associated to structural elements of the yard include its exterior walls, which comprised of stone (Bath Stone). Modern practice had altered these walls with the introduction of steel frames, which has the potential to reduce the character of the streetscape.
