Itajaí-Açu Formation
The Itajaí-Açu Formation () is a geological formation of the Santos Basin offshore of the Brazilian states of Rio de Janeiro, São Paulo, Paraná and Santa Catarina. The predominantly shale with interbedded turbiditic sandstones formation dates to the Late Cretaceous period; Cenomanian-Maastrichtian epochs and has a maximum thickness of . The formation is a reservoir rock of the fields in the Santos Basin. Etymology The formation is named after the Itajaí-Açu River, Santa Catarina. Description The Itajaí-Açu Formation is thick,Kiang Chang et al., 2008, p.32 and comprises a thick interval of dark grey clayey rocks, interbedded with the clastics of the Santos and Juréia Formations. Within this formation, the Ilhabela Member includes the turbiditic sandstones occurring along the section. The sedimentary environment is thought to be marine talus to open basin. Biostratigraphic data from palynomorphs, calcareous nannofossils and planktonic foraminifera indicate a Late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cenomanian
The Cenomanian is, in the International Commission on Stratigraphy's (ICS) geological timescale, the oldest or earliest age (geology), age of the Late Cretaceous epoch (geology), Epoch or the lowest stage (stratigraphy), stage of the Upper Cretaceous series (stratigraphy), Series. An age is a unit of geochronology; it is a unit of time; the stage is a unit in the stratigraphic column deposited during the corresponding age. Both age and stage bear the same name. As a unit of geologic time measure, the Cenomanian Age spans the time between 100.5 and 93.9 million years ago (Mya). In the geologic timescale, it is preceded by the Albian and is followed by the Turonian. The Upper Cenomanian starts around at 95 Mya. The Cenomanian is coeval with the Woodbinian of the regional timescale of the Gulf of Mexico and the early part of the Eaglefordian of the regional timescale of the East Coast of the United States. At the end of the Cenomanian, an anoxic event took place, called the Cenomani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a Clastic rock#Sedimentary clastic rocks, clastic sedimentary rock composed mainly of grain size, sand-sized (0.0625 to 2 mm) silicate mineral, silicate grains, Cementation (geology), cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar, because they are the most resistant minerals to the weathering processes at the Earth's surface. Like uncemented sand, sandstone may be imparted any color by impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Because sandstone beds can form highly visible cliffs and other topography, topographic features, certain colors of sandstone have become strongly identified with certain regions, such as the red rock deserts of Arches National Park and other areas of the Southwestern United States, American Southwest. Rock formations composed of sandstone usually allow the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
El Paso Corp
El Paso Corporation was a provider of natural gas and related energy products and was one of North America's largest natural gas producers until its acquisition by Kinder Morgan in 2012. It was headquartered in Houston, Texas, United States. Prior to the takeover by Kinder Morgan, the company owned North America's largest natural gas pipeline system which traveled from border-to-border and coast-to-coast. The pipeline system included Colorado Interstate Gas; El Paso Natural Gas; Southern Natural Gas; Tennessee Gas Pipeline; Cheyenne Plains Pipeline; Mojave Pipeline; Elba Express Pipeline; Young Gas Storage; Wyoming Interstate Company; and Ruby Pipeline. The El Paso Corporation also owned fifty percent of Great Lakes Transmission and Florida Gas Transmission and employed 6,000 people. Florida Gas is part of Southern Natural Gas. In 1999 the company doubled in size when it merged with Birmingham, Alabama based natural gas giant Sonat. It went on to acquire Coastal Corporation in 2001 ...
