Alpine orogeny, mountain-building event that affected a broad segment of southern Europe and the Mediterranean region during the Paleogene and Neogene periods (65.5 million to 2.6 million years ago). The Alpine orogeny produced intense metamorphism of preexisting rocks, crumpling of rock strata, and uplift accompanied by both normal and thrust faulting.

The Alpine Orogeny occurred mainly between 65 and 2.5 million years ago, although it is still active today. It saw the collision of the African and Eurasian plates, and the closure of the Tethys Ocean as oceanic lithosphere was subducted northwards beneath the Eurasian Plate, leaving today what we now know as the Mediterranean Sea.

01/11/2015 · Similar tectono-stratigraphic associations are observed in other high-pressure terranes of Alpine Corsica, suggesting that inherited OCT-type domains may be common in Alpine-type orogens.

Alpine T ethys and Neotethys extended eastward into the Dobrogea Orogen. Instead, the main branch of the Alpine T ethys linked up with the Meliata- Maliac-V ardar branch of …

01/11/2010 · The Inner Western Carpathians are composed of tectonic units that originated during the paleo-Alpine Orogeny in the Mesozoic. They comprise numerous nappes composed of low- to high-grade metamorphic and plutonic Palaeozoic rocks and largely unmetamorphosed Palaeozoic to Cretaceous strata, which in the area of our investigation are largely north-west …

The term ‘orogeny’ was coined by the American geologist, G.K. Gilbert, in 1890 to describe the process of mountain building. The term was originally used by Gilbert to describe the fold mountain belts of the Alps and the Rockies.

collision events in the Cretaceous period. The first overthrusting processes during the Alpine Orogeny already took place in the Jurassic, ca. 160 million years (Ma) before present. Today, the Earth’s crust is still being shortened in the eastern part of the Alps. Altogether, the Alpine Orogeny thus lasted from Jurassic until Recent.

Which of the accompanying sketches best illustrates an Alpine-type orogeny? A Sketch A B. Sketch B C. Sketch 33. Mountain building is most commonly associated with …
