Mesozoic and continues into the present. The formation of the Alps was a segment of this orogenic process, caused by the collision between the African and the Eurasian plates that began in the late Cretaceous Period. Under extreme compressive stresses and pressure, marine sedimentary rocks were uplifted, creating characteristic recumbent folds, or nappes, and thrust faults. As the rising peaks underwent erosion, a layer of marine flysch sediments was deposited in the foreland basin, and the sediments became involved in younger nappes (folds) as the orogeny progressed. Coarse sediments from the continual uplift and erosion were later deposited in foreland areas as molasse. The molasse regions in Switzerland and Bavaria were well-developed and saw further upthrusting of flysch. The Alpine orogeny occurred in ongoing cycles through to the Paleogene causing differences in nappe structures, with a late-stage orogeny causing the development of the Jura Mountains. A series of tectonic events in the Triassic, Jurassic and Cretaceous periods caused different paleogeographic regions. The Alps are subdivided by different lithology (rock composition) and nappe structures according to the orogenic events that affected them. The geological subdivision differentiates the Western, Eastern Alps, and Southern Alps: the Helveticum in the north, the Penninicum and Austroalpine system in the centre and, south of the Periadriatic Seam, the Southern Alpine system. According to geologist Stefan Schmid, because the Western Alps underwent a metamorphic event in the Cenozoic Era while the Austroalpine peaks underwent an event in the Cretaceous Period, the two areas show distinct differences in nappe formations. Flysch deposits in the Southern Alps of Lombardy probably occurred in the Cretaceous or later. Peaks in France, Italy and Switzerland lie in the "Houillière zone", which consists of basement with sediments from the Mesozoic Era. High "massifs" with external sedimentary cover are more common in the Western Alps and were affected by Neogene Period thin-skinned thrusting whereas the Eastern Alps have comparatively few high peaked massifs. Similarly the peaks in eastern Switzerland extending to western Austria (Helvetic nappes) consist of thin-skinned sedimentary folding that detached from former basement rock. In simple terms, the structure of the Alps consists of layers of rock of European, African, and oceanic (Tethyan) origin. The bottom nappe structure is of continental European origin, above which are stacked marine sediment nappes, topped off by nappes derived from the African plate. The Matterhorn is an example of the ongoing orogeny and shows evidence of

        'QUESTION: What caused the formation of the Alps?': 'ANSWER: The formation of the Alps was caused by the collision between the African and the Eurasian plates.',
        'QUESTION: When did the formation of the Alps begin?': 'ANSWER: The formation of the Alps began in the late Cretaceous Period.',
        'QUESTION: How were the mountains formed during the formation of the Alps?': 'ANSWER: Marine sedimentary rocks were uplifted due to extreme compressive stresses and pressure, creating characteristic recumbent folds, or nappes, and thrust faults.',
        'QUESTION: What happened after the initial mountain formation during the Alps formation?': 'ANSWER: After the initial mountain formation, the rising peaks underwent erosion, leading to deposition of marine flysch sediments in the foreland basin, which then got involved in younger nappes as the orogeny progressed.',
        'QUESTION: What is the term used for the continuous cycle of mountain building and destruction during the Alps formation?': 'ANSWER: This continuous cycle of mountain building and destruction is called the Alpine orogeny.',
        'QUESTION: Can you tell me about the three main divisions of the Alps based on their geological features?': 'ANSWER: Yes, the Alps are divided into the Western Alps, Eastern Alps, and Southern Alps. These divisions are based on the geological features such as rock compositions and nappe structures resulting from various orogenic events.',
        'QUESTION: Why do the Western and Austroalpine peaks show distinct differences in nappe formations?': 'ANSWER: The Western Alps experienced a metamorphic event in the Cenozoic Era, while the Austroalpine peaks went through an event in the Cretaceous Period. Therefore, these two areas exhibit distinct differences in nappe formations.',
        'QUESTION: Where can we find the "Houillère zone"?': 'ANSWER: The Houillière zone lies in high peaks located in France, Italy, and Switzerland, consisting of basement with sediments from the Mesozoic Era.',
        'QUESTION: What type of mountains are found in eastern Switzerland extending to western Austria?': 'ANSWER: The mountains found in eastern Switzerland extending to western Austria consist of thin-skinned sedimentary folding that detaches from the former basement rock.',
        'QUESTION: What is the basic structure of the Alps?': 'ANSWER: The basic structure of the Alps consists of layers of rock of European, African, and oceanic (Tethyan) origins. The bottom nappe structure is of continental European origin, followed by marine sediment nappes, and finally those derived from the African plate.'
