Sedimentary Structures and Fossils. Through careful observation over the past few centuries, geologists have discovered that the accumulation of sediments and sedimentary rocks takes place according to some important geological principles, as follows: The principle of original horizontality states that sediments accumulate in essentially ...
Fossil spring deposits are common in the southern Great Basin, and their distribution provides important constraints on the hydrologic response of the regional water table to climate change. This information is crucial, because the proposed highlevel nuclear waste repository at Yucca Mountain will be loed ∼200–400 m above the modern water table.

Geology of Nigeria Sedimentary Series in 7 basins • Niger Delta, Dahomey, Anambra, Bida, Benue related to the opening of the Gulf of the Guinea. • Sokoto and Chad basins are part of larger basins outside Nigeria.
· Hence, this research work used some geophysical approach and investigated economy mineral deposits in Gubio area, which is part of the Nigerian sector of Chad basin, which falls within latitudes 12°00′ to 13°00′ North and longitudes 12°30′ to 14°00′ East.
Fossil Sites in the Bighorn Basin The Bighorn Basin of Wyoming contains extensivelydocumented fossilbearing deposits that date from 550 million years ago (Cambrian Period) to the present. These include worldfamous outcrops that contain dinosaur bones, tracksites, ancient marine reptiles, and primitive mammal fossils.
· Since 2007, Sidor and his team of students, postdoctoral researchers, paleontologists and geologists have visited the Ruhuhu Basin of Tanzania five times and the Luangwa and midZambezi basins of Zambia four times. They lived there for about a month at a time, often hiking for miles to find fossil sites and camping in villages and national parks.
In 1908, the German Nigerian Bitumen Corporation drilled the first wells in the vicinity of the tar seep deposits in the northern portion of the delta (Frost, 1997). However, significant oil shows were not found in Tertiary rocks until the early 1950's. ShellBritish Petroleum brought the first well on stream in 1958 at 5,100 barrels per day.
Detailed fieldwork in parts of the Benin (Dahomey) Basin SW, Nigeria has allowed the recognition of sedimentary successions deposited in different continental depositional environments interpreted as fluvial sedimentation characterised by abandoned channels and subaerial exposure features. The lithofacies recognised are: conglomerates, debris flow deposits, very coarse grained sandstone ...

ABSTRACT—Fossil fishes were first collected from deposits of the Sangkarewang Formation of the Ombilin Basin in Sumatra, Indonesia, in the 1870s, but a comprehensive study of these fishes was not published until almost 50 years later. New material from these deposits was collected in 2009, which included a small anabantoid fish.
Since the fossils reported from the Pinto Basin date to the Pleistocene Epoch (Jefferson, 1973, 1986, 1991a), as confirmed herein, these fluviolacustrine sediments and the Pleistocene fossil bearing lake sediments are preliminarily interpreted here to be distinct lithologic units.
The basin is contiguous or adjacent to the Anambra basin to the east and these basins were major depositional axes for transgressive and regressive sediments in the late Cretaceous times of Nigeria. To the Northwest, it is adjacent to the Sokoto basin. Table 1: Stratigraphic succession and lithologic assemblage in the Bida basin AGE
basin . The present study examines the stratigraphic succession of Benin and Western Nigeria Offshore Basins and attempts to compare these stratigraphic nomenclatures. It is a preliminary stage process aiming to give additional information for the beginning of a Stratigraphic Harmonization Project concerning sedimentary basins of the
Nigeria has an oil shale deposit of high economic value and this is found in Imo (Okigwe) and Abia State, other Africa countries with oil shale reserves include South Africa, Egypt, and Madagascar. Just like tar sand that has a significant amount of oilrich bitumen, oil shale also has a quiet amount of oil that can be used to produce various grades of petroleum products.
1. Introduction. The X2 well, is loed in the Greater Ughelli Depo Belt, Niger Delta Basin (), which lies between latitudes 4° N and 6° N and longitudes 3° E and 9° E in the southsouth geopolitical region of Nigeria delta complex contains a sedimentary thickness of over 12,000m, which consists of three anachronous Lithostratigraphic units.

The Iullemmeden Basin with its pentagonal shape extends through five countries: Niger, Nigeria, Mali, Algeria, and Benin. It covers an area of about 800 000 km2 and is bounded by: the Adrar des Iforas, the Hoggar, and the Air mountains in the north; the Gourma and Liptako massives
