Chorowicz (1999) defines Anatolia as a product of the African and Eurasian plate collision which formed mainly from lithospheric magma. A widespread of magmatism accompanied plate tectonism experienced in this region during the Cenozoic era. The late Eocene (37.3 ± 4.6, measure through K-Ar radiometric dating) marks the initial period where this magmatism in took place. This essay will establish if whether an East-west spatial control on the chemistry of Anatolian volcanics exists. Spatial control is a geographical process in space which didctates how the events of a certain process in space take place.

Geological Setting The Cape Granite Suite formed about 560-520 Ma during the Saldanian orogeny which occurred between 780 to 510 Ma (Harris & Vogelli, 2010; Villaros, Stevens & Buick, 2009). This orogeny formed as a result of the convergence of the Rio de la Plata and Kalahari cratons during the formation of Gondwanaland (Harris & Vogelli, 2010). The granitoids of the CGS were intruded into the three terranes of the metasedimentary and metavolcanic Malmesbury Group which are divided by distinct north-west trending shear zones (Scheepers, 2000). These terranes include the southwestern Tygerberg terrane, Swartland terrane at the centre and Boland terrane to the north east (Fig. 1) (Scheepers, 1995).

Both the upper and lower members within the Bakken Formation are black shales (Jiang, 2001). The black shales in the upper and lower members formed offshore in anoxic condtinos. The shales in the upper and lower members of the Bakken Formation are composed of hard silicous and pyritic components (Webster, 1984). These members are also fissile and non calcareous and contain numerous amounts of conodonts and oth... ... middle of paper ... ...f Petroleum Engineers, DOI: 10.2118/90697-MS. Julie A.

2. The backbone of the Antarctic continent The Transantarctic Mountains (TM) extend for over 3000 km across the center of the continent and delineate the two major tectonic provinces of Antarctica: the stable East Antarctic craton and the WARS (Stump, 1995; Elliot, 2013). The formation of the TM initiated in the Neoproterozoic as the supercontinent Rodinia rifted along their current location. During the Cambrian, this environment evolved into a convergent plate boundary (Elliot, 2013). The associated orogenic event is known by different names regionally: the Ross orogeny in Antarctica, the Delamerian orogeny in SE-Australia, and the Tyennan orogeny in Tasmania (Federico et al.
