Different Types of Sedimentary Basins There is upwards of 144 sedimentary basins identified just in the United States, whether they may be onshore or offshore (Coleman, 2012). The day-to-day classification used for most basins is quite simple and is based on the scheme: if basins are formed within or near the margins of a craton, basins that are formed between cratons and extends onto oceanic crust, and basins which form on oceanic crust for the most part and are independent of cratons (Coleman, 2012). Following with the same classification scheme, basins can be put into these four basic groups; however, these groups have more specific subgroups within, twelve (12) total to be exact. While this is true, for this paper, only three…show more content…
(See graph on next page) The province, itself covers between 50,000 and 70,000 square miles, and just throughout the southern region of the basin, contains sedimentary rocks that most likely exceed 40,000 feet deep. More than half of the strata within, ages from Cambrian to Permian, being a part of the gas fields that are said to be the largest producers of hydrocarbons in the basin. The Anadarko is one of the most prolific hydrocarbon producers in the continental United States (Hugman and Vidas, 1987; Johnson, 1988). There are only minor occurrences of Mesozoic and Cenozoic strata in the northwest part of the province (Henry). Rocks aging older than Mississippian are predominately carbonates, while younger rocks consist of mainly shales and some sandstones - why are these important? Well, while the only make up only a small part of the basin, they account for the large mass of petroleum production (Henry). The Fundy Basin It is believed that the Fundy Basin got its name due to being ironically located just south of the Cobequid-Chedabucto Fault system in Nova Scotia and beneath the infamous Bay of Fundy (Wade, 1996). This basin, in particular, is considered one of the ‘failed-rifts’ of the “half-graben” formed by the mid - late Triassic break up of Pangea. The Fundy Basin is a sediment-filled, proto-oceanic rift basin located along the margin of the Atlantic coast of
