The Melanesian Arc Of Papua New Guinea

Although there are other volcanic events that don’t prove that the tectonic theory is valid. For example The "Ring of Fire" is an arc stretching from New Zealand, along the eastern edge of Asia, north across the Aleutian Islands of Alaska, and south along the coast of North and South America. The Ring of Fire is composed over 75% of the world's active and dormant volcanoes. This huge ring of volcanic and seismic (earthquake) activity was noticed and described before the invention of the theory of plate tectonics theory. Also without movement at the boundaries around the Pacific, volcanoes such as Mt St Helens would simply not exist, as they would have no fuel caused by the subduction of an oceanic plate under a continental plate.

Volcanic and Seismic events are major pieces of evidence towards proving that plate tectonics theory is valid (40 marks)

The Island of Hawaii sits on (almost in the middle of) the Pacific Plate. The Pacific Plate is a giant jigsaw piece of the Earth’s crust that is slowly moving in a northwesterly direction. It moves about four inches a year. There is a basically stationary hot spot deep within the Earth’s mantle. Heat from this hot spot makes molten lava and rock (magma) that rises through the Pacific Plate and erupts continuously on the ocean floor. After thousands of eruptions and over many many years, an island forms a rocky

The youngest of these rocks are dated at about 220,000 years ago. Rhyodacties and quartz latites in the modern caldera area extruded from about 320,000 years ago to 260,000 years ago, and then silica-rich rhyolites at Glass Mountain northeast of the caldera erupted from about 210,000 years ago to 80,000 years ago. The scattered distribution of the initial mafic eruptions indicates that they were erupted from the mantle, while the slightly younger domes and flows were from a deep-crustal source. The youngest rhyolite eruptions erupted at the northeast rim of the caldera at Glass Mountain and were the first activity of the silicic Long Valley magma chamber (Bailey, et. al., 1989).

Sims et al. (1989) synthesized U-Pb zircon ages for the Pembine-Wausau terrane. Sims concluded that the volcanic rocks were generated from around 1889 to 1860 Ma as island arcs and closed back-arc basins above the south-dipping subduction zone (Niagara fault zone). Granitoid rocks in the terrane, emplaced from around 1870 to 1760 Ma, are mainly granodiorite and tonalite but include gabbro, diorite, and granite. These developed as island arcs above the Eau Pleine shear zone. The Niagara fault zone contains a relict ophiolite, suggesting that the rocks in the Pembine-Wausau terrane probably accumulated on

The, “Sorrow of the Lonely and the Burning of the Dancers”, is a ethnography written by anthropologist Edward Schieffelin, derived from his fieldwork with the Kaluli people of Papua New Guinea. The main focus of the book of the book is how many of the fundamental notions that are implicit in Kaluli culture are found in the Gisaro ceremony, which Schieffelin uses as, “a lens through which to view some of the fundamental issues of Kaluli life and society” (p1).

Schulz’s article is split into five sections. The first section introduces the readers to Chris Goldfinger, a paleoseismologist at Oregon State University. Goldfinger was at a seismology conference in Kashiwa, Japan when the 2011 Tohoku

One of the major things noticeable from the cross section is that quite a few of the rock layers are over turned, where the older rock layers are above the newer rock layers. This is seen in the contact between the Quartz Monzonite of Papoose Flat and the Campito Formation which is also a disconformity. Next there is some fault zones separating the Camptio, Poleta, and Harkless formations. We then see some more overturned layers with the contacts between Saline Spring Valley Formation (lower and upper members) above the Mule Spring Formation along with some inferred folding. With a normal fault separating the inferred folding event, we see where the overturning occurs. In between the Cambrian layers we see Tertiary Basalt nonconformities also being folded, thus with that we know that the folding event was more recent than the formation of the Basalt. Next there is a large Basalt field with a spot of the Harkless formation. Again we see over tuning as the Basalt field ends there are the Devonian and Mississippian rock Layers on top of the basalt. Separating these overturned layers from the Harkless Formation and the Saline valley Formation (upper member), which are not overturned, is a thrust fault. From this information, there was a major stress event sometime after the Tertiary period causing the rock layers to fold and overturn. And from this stress event and from the folding, normal and thrust faults are formed. Finally we see that there were alluvial and landslide deposits from the Quaternary after the folding, faulting, and over

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.

The first deformation event (D1) resulted in folding of volcanic rocks in the Wabigoon and Wawa subprovinces (Hooper and Ojakangas, 1971; Hudleston, 1976; Hudleston et al., 1987; Jirsa et al., 1992) and locally within the Quetico subprovince (Bauer, 1985b). Most D1 folds in the Wawa terrane in MN rarely display axial-planar cleavage, with Bauer (1985b), Hooper and Ojakangas (1971), Hudleston (1976), and Jirsa et al. (1992) having identified cleavage (S1) development locally in the Vermillion greenstone belt (Peterson, 2001). In the Wabigoon terrane, D1 resulted in recumbent folding that overturned the stratigraphic sequence and the first regional schistosity (Poulsen et al., 1980). S1 is generally subparallel to the layering in the metavolcanic and metasedimentary rocks, and a gneissic foliation attributed to D1 is well developed in gneissic domes (Czeck and Poulsen, 2010). Although D1 likely created significant thrust or oblique faulting, direct evidence

Hildebrand, (2009, 2003) attempts to integrate both observed geologic features (hinterland high grade metamorphism, Laramide basement uplifts, Cordilleran batholiths, regional-scale Neogene extension) and the lack of observed features (large scale strike/slip faults), while matching paleomagnetic data (large amounts of northward motion in the oceanic realm exist with no evidence on land) (Fern Esperanza beetle-Moorcroft, MS Thesis, 2014).

According to the Merriam Webster dictionary, the word ‘geography’ is defined as “a science that deals with the description, distribution, and interaction of the diverse physical, biological, and cultural features of the earth's surface.” This simple word with its inquisitive definition were the answer to Papua New Guinea native, Yalle’s question for Dr. Jared Diamond on the success of white people. Papua New Guinea is a country in the Pacific that has existed for over 40,000 years. Jared Diamond has spent many months with the natives, learning their way of life but has never understood why the people have not been as successful as the Europeans were. Yalle had the same question for Diamond. At first when Diamond was faced with this thought-provoking

Oceania is the vast swath of the South Pacific islands that lie beyond Southeast Asia. Divided into regions in 1831 by “geographical, racial and linguistic distinctions” by the French explorer Jules Dumont d’Urville (Kliener, p. 1104). While the islands were discovered by Europeans in the 16th century, it is clear that these Oceanic cultures and people existed far in advance of their discovery. Kliener states that these cultures and people “inhabited the islands for tens of thousands of years” (p. 1104). Expansive exploration and migration brought explorers to these islands through the 19th century, the likes of which caused various types of turmoil for the local people. While colonization and exploration caused riffs for the locals, it also

The Kaluli are a small clan of indigenous people who live in the rain forests in the Southern Highlands of the Great Papuan Plateau found in Papua New Guinea. The Kaluli people’s residency includes up to twenty longhouses each with about fifteen families in them, numbering roughly to about sixty to ninety people in each longhouse. The Kaluli culture does not involve any ranked social structure or individuals with hierarchical authority over others, however relies on strong egalitarian and equal values. The purpose of this of this paper is to highlight the Kaluli people’s identity, their unique upbringing and their struggles faced by missionization. This text will first identify how Kaluli children, both male and female are socialized and encultured in different ways through the mother enforcing certain traits, attitudes, behaviors, traditions and work ethics. Secondly this text will consider how missionization, i.e. the communication of other cultures and the indoctrination of Christianity by missionaries has disrupted the Kaluli’s sense of place. It will focus on the introduction of European-based time, the introduction and demise of some types of languages and the ownership of land and identity. Thirdly this paper will discuss how the enculturation of Kaluli children differs from more civilized enculturation of children and possible reasons for this
