	Petroleum geology - Wikipedia, the free encyclopedia
		Petroleum geology refers to the specific set of geological disciplines that are applied to the search for hydrocarbons (oil exploration).
		Petroleum geology is principally concerned with the evaluation of seven key elements in sedimentary basins:
		Traditionally, these were determined through the study of hand specimens, contiguous parts of the reservoir that outcrop at the surface and by the technique of formation evaluation using wireline tools passed down the well itself.

	Morrison Formation - Wikipedia, the free encyclopedia
		According to radiometric dating, the Morrison Formation is between 145 and 154 million years old (Ma), which places it in the latest Oxfordian and Kimmeridgian stages of the late Jurassic.
		This is similar in age to the Solnhofen Limestone Formation in Germany and the Tendaguru Formation in Tanzania.
		Coal is found in the Morrison Formation of Montana, which means that the northern part of the formation, along the shores of the sea, was wet and swampy, with more vegetation.

	Ozark Plateaus
		Geology: The Cotter Dolomite is composed of dolostone of predominantly two types: a fine-grained, argillaceous, earthy textured, relatively soft, white to buff or gray dolostone called "cotton rock", and a more massive, medium-grained, gray dolostone that weathers to a somewhat hackly surface texture and becomes dark on exposure.
		Geology: The Joachim Dolomite is chiefly a fine-grained dolostone and dolomitic limestone with thin beds of shale.
		Geology: The formation is chiefly an even-bedded, thin to massive, light- to pinkish-gray, fine- to coarse-grained, bioclastic limestone with a characteristic surgary texture.

	AllRefer.com - clay : Formation (Geology And Oceanography) - Encyclopedia
		Clays are divided into two classes: residual clay, found in the place of origin, and transported clay, also known as sedimentary clay, removed from the place of origin by an agent of erosion and deposited in a new and possibly distant position.
		One of the commonest processes of clay formation is the chemical decomposition of feldspar.
		Clay consists of a sheet of interconnected silicates combined with a second sheetlike grouping of metallic atoms, oxygen, and hydroxyl, forming a two-layer mineral such as kaolinite.

	Geology of Iceland
		The Tertiary Basalt Formation (TBF) mainly appears in two large regions on eastern and western-northwestern Iceland, on either side of the active rift zones transecting the country (Fig.
		The Upper Pliocene and Lower Pleistocene Grey Basalt Formation (PPF) is confined mainly to a broad SW-NE trending zone between the Tertiary plateau basalt areas and the active rift zone (Fig.
		As in the Tertiary Basalt Formation, volcanic rocks of basaltic composition are the most common rock type in the Pliocene-Pleistocene succession.

		On top of the Salitral Formation is a second conglomeratic sandstone – mudstone sequence composed of the Poleo Formation, a medium-bedded, yellowish-gray micaceous sandstone with conglomeratic lenses of siltstone and calcrete clasts, overlain by a thick red to reddish brown mudstone, the Painted Desert Member of the Petrified Forest Formation.
		The Todilto Formation was most likely deposited in a salina (Lucas et al., 1985); in other words, in a moderately deep, oxygen-poor, body of saline water that was isolated from the main body of the Jurassic ocean by a barrier.
		The Burro Canyon Formation consists of cross-bedded medium to fine-grained sandstone, quartz and chert pebble conglomerate, and pale-green to pale-red mudstones (Ridgley, 1977; Ridgley 1987; Owen et al., 2005).

	Geology Field Guide - Hordle Cliff, Hampshire - Upper Eocene strata
		The Headon Hill Formation (of the Solent Group) form part of the well-known Hampshire Basin, and is exposed at Hordle Cliff, west of Milford-on-Sea, in Christchurch Bay, and also at Headon Hill, the type locality near Alum Bay and Whitecliff Bay, in the Isle of Wight.
		To the left of the Chalk are the vertical coloured sands of Alum Bay and to the left of those (actually to the northeast of them) is Headon Hill from which the strata of Hordle Cliff take their name.
		In this image, Environmental Geology students from Southampton University are assessing the variation in the extent of coast erosion along the stretch of cliff immediately east of Becton Bunny (and west of Long Mead End).

	Jurassic Morrison Formation Ecosystem
		This colorful formation is known worldwide for the skeletons of large dinosaurs, especially the giant sauropods, that have been recovered from it and displayed in many museums throughout the world.
		Another closely related formation that correlates with the lower part of the Morrison on the Colorado Plateau and farther north is the Ralston Creek Formation, which is only recognized in the Front Range foothills west of Denver.
		Farther south in southeastern Utah and in western and eastern Colorado, gypsum in the Tidwell Member and correlative Ralston Creek Formation was precipitated as evaporite deposits in hypersaline lagoons at the southern margin of the seaway.

	The Himalayas - Geology - Formation of the Himalayas
		They are known as fold mountains because the mountains extend for 2500 km in length in a series of parallel ridges or folds.
		The accepted theory about the formation of the Himalayas started to take shape in the year 1912 when German meteorologist Alfred Wegener developed his Theory of Continental Drift.
		The Alps in Europe are another example of a mountain chain that formed due to the collision of tectonic plates.

		Lying on top of the Carmelo Formation, like frosting on a cake, is the third geologically significant type of rock found at the reserve: sedimentary rocks that were deposited on ancient marine terraces.
		It is softer than the granodiorite and is easily seen along the south shore of the reserve, where it has been eroded by ocean waves to form a photogenic series of coves, crevices and shelves.
		This formation is the basement rock which underlies all of Point Lobos.

	Grand Hikes: The Grand Canyon Supergroup Formations
		The most ubiquitously exposed geologic formations in Grand Canyon are the Kaibab, Toroweap, Coconino, Hermit, Supai Group, Redwall, Muav, Bright Angel, and Tapeats (all sedimentary rocks of Paleozoic Era origin) and the highly altered basement rocks of the Vishnu Group underlying them, which was deposited and subsequently metamorphosed during early Proterozoic time.
		These Paleozoic formations cover the contorted, crystalline Vishnu rocks like layers of a cake and are stacked one upon the other in an orderly and continuous fashion.
		Most of these formations are yet further subdivided into up to 4 or 5 constituent members based on their lithologies.

	Geology and Formation of the Famous Flowerpot Rocks
		The fascinating geology of the natural rock formations at the Hopewell Rocks, on the Bay of Fundy, is a history worth learning.
		Today, while walking along the ocean's floor at low tide, visitors can see the evidence of this tilting in the layers of rock in the rock face, the vertical cracks which are the genesis of new formations, and the telltale high tide marks along the cliffs.
		Most visitors, clambering over clusters of rounded mounds cloaked in rockweed are unaware that these are the burial mounds of age-old formations, toppled by the tide, and slowly disintegrating as the Tides of Fundy continue to sculpt the flowerpots of the future and erase those of the past.

	Oilfield Glossary: Term 'formation'
		A body of rock that is sufficiently distinctive and continuous that it can be mapped.
		In stratigraphy, a formation is a body of strata of predominantly one type or combination of types; multiple formations form groups, and subdivisions of formations are members.
		In the context of formation evaluation, the term refers to the volume of rock seen by a measurement made in the borehole, as in a log or a well test.
