Pab Formation
The Pab Formation is a Late Cretaceous geologic Formation (geology), formation in Balochistan, in western Pakistan. It is dominated by Sandstone, with minor mudstone and shale components. Dinosaur remains are among the fossils that have been recovered from the formation.Weishampel, et al. (2004). "Dinosaur distribution." Pp. 517-607. Fossil content Among the following fossils were reported from the formation: * ''Balochisaurus'' * ''Brohisaurus'' * ''Gspsaurus'' * ''Induszalim'' * ''Khetranisaurus'' * ''Khuzdarcroco'' * ''Marisaurus'' * ''Pabwehshi'' * ''Pakisaurus'' * ''List of informally named pterosaurs#Saraikisaurus, Saraikisaurus'' * ''Sulaimanisaurus'' * ''Sulaimanisuchus'' * ''Vitakridrinda'' See also * List of dinosaur-bearing rock formations ** List of stratigraphic units with indeterminate dinosaur fossils References Bibliography * Geologic formations of Pakistan Upper Cretaceous Series of Asia Maastrichtian Stage Sandstone formations Paleontology in P ...

Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Wer ...

Geologic Formations Of Pakistan
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of Earth ...
