Calcare Di Aurisina
The Calcare di Aurisina (Also known as Aurisina Formation, “Formazione di Monrupino”, Trieste Karst Limestone formation, “Repen formation”, “Sežana formation” and “Lipiza formation”) is a Mesozoic geologic Formation (geology), formation in Italy and Slovenia. This Limestone, limestones are found in the Trieste area and are of Late Cretaceous (Santonian-Campanian) age, being a local record of Carbonate platform limestones, historically quarried by cutting large blocks using steel wire, what has allowed more access to them, as numerous quarries allow excellent exposure. Due to being cut into large blocks and slabs, that usually end stored near the quarries, detailed, three-dimensional study of the rock's composition and fossils can be easily done. Characteristics The ''Aurisina limestone'' has usually a light grey background, sometimes appearing hazelnut in color. It is known for its high purity, compactness, and uniformity. The quarries where it is extracted co ... [...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 (geology), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
