Calcare Di Bari
The Calcare di Bari (Italian for Bari Limestone) is a Cretaceous (Valanginian to Turonian, early Turonian, spanning approximately 45 million years) geologic Formation (geology), formation in Apulia, southeastern Italy. The formation comprises micrite, micritic limestones, in places karstified and dolomitization, dolomitized. Rudists and fossil ankylosaur, sauropod and theropod tracks have been reported from the thick formation that was deposited in an inner carbonate platform depositional environment, environment towards the top dominated by rudist reefs. Description The Calcare di Bari underlies the Calcare di Altamura, separated by an unconformity (geology), unconformity. The base of the formation is not recognized in outcrop.APAT, 2001, p.31Reina & Buttiglione, 2005, p.31 The Calcare di Bari is subdivided into the Avvantaggio, Montericco, Palorbitoline, Corato, Bisceglie and Sannicandro Members. The formation outcrop, crops out around the Bari–Taranto railway.Reina & Buttigl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
