1. The Tasman Orogeny is represented in the basement rocks or eastern Australia. The rocks make up one third of Australia’s landmass. The orogeny extends along the eastern seaboard from the Tasmania in the south to Queensland in the north. In the early Paleozoic to early Mesozoic Australia was located on the eastern side of the Gondwana super continent. It was situated above Antarctica to the northeast of India. The tectonic processes that increased in the size of the Australian continent to the size that it is today are a series of terranes accreted to the continent. The Tasman orogeny is made up of smaller orogenys the Tasman line, Thomson Orogeny, Lachlan Orogeny, Delamerian Orogeny and the New England Orogeny.

The most common use for resistivity logging is drilling for oil and gas. The rock material are insulators while the fluids, like oil and water, are conductors. If a formation is porous, the resistivity will be low. If the formation contains hydrocarbon or has a low porosity, it will have a high resistivity. The high resistivity may show that the drill has entered a hydrocarbon bearing formation.
3. The North American Cordillera is a mountainous region of Western North America. The North American Cordillera is the longest-lived orogenic belt know on earth. It spans time from the Precambrian to the Cenozoic. There is a lot of folding and faulting in the region and the faulting mainly consists of strike-slip faulting and extensional rifting. The Basin and Range province is a large part of the Cordillera. The Basin and Range resulted when the subducting slab fell away and the heat triggered extensional collapse of much of the Western US. The Basin and Range is the youngest of the systems and reflects 200-300 Km of extension from east to …show more content…
It was also said that the Cordillera were not fundamentally caused by the accretion of allochthonous terranes and that magmatism may have played a more crucial role in the formation process. If I had millions to explore more about the Cordilleras, I would probably look more at the San Andreas Fault. I’ve always had some interest in it ever since I heard California would detach from the rest of the USA and float away, even if that isn’t true. The Appalachian Orogeny is located on the eastern side of the USA. It has a total strike distance of 3000 Km and consists of three major realms, the Laurentian, Axial, and the Peri-Gondwanan Realm. These realms all have smaller zones within them that were accreted to the Laurentian craton from the early Cambrian to the early Ordovician. The building of the Appalachian Orogeny can be attributed to the accretion of exotic terranes and volcanic island arcs that were present in the Iapetus Ocean. The Iapetus Ocean is the ocean preceding the Atlantic. Through the accretion of exotic terranes and volcanic arcs compression occurred. This compression is what gives us the Appalachian
