Kangaroo Point Cliffs Essay

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

Silicious lava, forced up from deep down below. Soda trachytes extruded in a highly viscous state, building the steep-sides mametons we see in Hanging Rock. And quite young, geologically speaking. Barely a millions years old. (Greene, 11)

New South Wales West locates one of the greatest archaeological sites in Australia’s history, that is, Lake Mungo.

Proof of volcanic activity related to the break-up of Australia and Antarctica is seen at Bunbury, which is located 150km south of Perth, at the point where the basalt is of early Cretaceous, also on the middle Jurassic Kangaroo Island. However, evidence of Cenozoic eruptions is only seen in Eastern Highland. All through the Cenozoic, hot spot volcanic event transpire (Sutherland et al., 1985). Most of these events follow the Miocene (Stephenson et al., 1980) with recent eruptions close to the southern and northern margin of volcanic zone at southeast of South Australia and north Queensland respectively.

This chamber gave birth to the cataclysmic eruption of 760,000 years ago, and is connected to the magma which erupted from the chain of rhyolite domes that stretch up to the northwest. Eruptions crept sequentially along this line, beginning with the Bishop Tuff eruption and most recently displaying activity in the middle of Mono Lake at the island Negit. This most recent volcanism of the Inyo-Mono crater eruptions occurred as late as 1850 A.D (Bailey, et. al., 1989).

Melbourne is located in the south-eastern part of mainland Australia, within the state of Victoria. Geologically, it is built on the confluence of Quaternary lava flows to the west, Silurian mudstones to the east, and Holocene sand accumulation to the southeast along Port Phillip. The southeastern suburbs are situated on the Selwyn fault which transects Mount Martha and Cranbourne.

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

With its glorious old sandstone buildings (which gave the area its name), The Rocks a hodgepodge of cobblestone streets dating back to the city’s settlement. Sydney's convict history can be seen in historic pubs and

An important event before the Eureka Stockade was the build up to it. It all started as the Ballarat gold fields started getting popular and attracting different nationalities form all over the world. As this was happening the government thought that they could make money out of this and bought in mining licences and taxes which all

A period of volcanism resulted in igneous intrusions within the Raton Basin-Sierra Grande Uplift Province that was sourced from the upper mantle about 26. 6 billion years ago and is associated with parallel dikes and sills (Higley, 2007). Igneous rocks are common within the Raton Basin and include Tertiary dikes and sills that range in age from 6.7 to 29 5 million years ago (Flores and Bader, 1999). One of the main differences between dikes and sills is that dikes are longer lived magma conduits and sills are features that form when magma is in neutral buoyancy with the surrounding rock (Rooper et al., 2006). These volcanic events are associated with hydrothermal alteration of coal within the basin (Higley, 2007).

Bondi-beach is one of Australia’s most famous beaches in Sydney. It is located on the east coast of Australia and is a suburb of the city of Sydney. ‘Bondi’ or ‘Boondi’ is an Aboriginal word meaning water breaking over rocks or noise of water breaking over rocks (Frances Pollon, 1990). In 1851, Francis O’Brien and Edward Smith Hall purchased 200 acres of the Bondi area which was named ‘The Bondi Estate’. During this period the beach was accessible to the public as a picnic ground and playground for families; Because the site quickly became popular it was endanger to become private to the public, yet the Municipal Council believed that the Government needed to negotiate the issue in order to make the beach a public reserve. The area was a working

Other than its unique name, Capital Reef lies “along a north-south- trending monocline, called the Water Pocket Fold.”(pp.56 text book.) “Waterpocket Fold derives its name from depressions in the sandstone which hold water after a rainfall known as waterpockets,

Australia has so many fascinating sites and attractions, one of them, and my personal favorite is

The volcanoes are located where there is a divergence or convergence in the tectonic plates and bring their lava from the deepest of the terrestrial mantle. The materials and explosions of these ginates represent a constant risk in the places inhabited by the human being, nevertheless the people ususually live in these areas no matter the risk. On the other hand the volcanos can change the geology of an impressive form, or to cool the temperature of the earth, or to darken the sky. The scientific community increases its efforts to try to understand better what happens in volcanoes, however it is impossible to predict these conditions.

As the eruption wore on, it later produced a phase with red hot pyroclastic surges and flows, along with other volcanic material. This was referred to as the “Peléan” phase. These type of eruptions are known for the mentioned pyroclastic flows, along with hot mud surges. (Universe today) This phase was speculated to have begun during the latter part of the eruption, and is largely regarded as the main killer of most of the surrounding inhabitants. (Museum timeline)
