Voronezh Massif (also Voronezh Anteclise Russian : Воронежская антеклиза , or Voronezh Uplift ) is a tectonic anteclise in the south of the Central Russian Upland with a high occurrence of the Precambrian basement . It lies to the southwest of the town of Voronezh , Russia.
5-742: The massif covers the southwest area of European Russia . Ukraine lies to the southwest, while Belarus is to the west. The massif is bordered northwest of the Orsha depression and Zhlobin saddle, south-west and south of the Pripyat-Donetsk aulacogens , east of the Caspian Basin , and northeast of the Moscow Basin . The Voronezh Massif stretches 800 kilometres (500 mi) from northwest to southeast, and between 300–400 kilometres (190–250 mi) wide. The basement rocks usually occur at
10-676: A depth of 40–250 metres (130–820 ft), sometimes coming to the surface of the Earth. The north-eastern and eastern slopes are gently sloping, while the southern slope is steeper. Two megablocks are distinguished in the structure of the Precambrian basement of the VCM: the eastern (Voronezh), composed of Lower Proterozoic 6 formations, and the western (Kursk), characterized by the predominant distribution of Archean rocks, among which Lower Proterozoic deposits are observed only in narrow linear zones of
15-407: Is a principal mountain mass, such as a compact portion of a mountain range , containing one or more summits (e.g. France's Massif Central ). In mountaineering literature, a massif is frequently used to denote the main mass of an individual mountain. As a purely scientific term in geology , however, a "massif" is separately and more specifically defined as a section of a planet's crust that
20-402: Is demarcated by faults or flexures . In the movement of the crust, a massif tends to retain its internal structure while being displaced as a whole. A massif is a smaller structural unit than a tectonic plate and is considered the fourth-largest driving force in geomorphology . The word "massif" originates from French (in which the word also means "massive"), where it is used to refer to
25-664: The southeast – northwest strike. in the east, the platform is covered by sedimentary rocks of the Riphean and Vendian periods. The southern portion consists of Devonian , Permian and Triassic cover, with some other Mesozoic and Cenozoic rocks. The Voronezh anteclise formed mainly in the Hercynian orogeny . The Voronezh anteclise contains iron ore of the Kursk Magnetic Anomaly . Massif A massif ( / m æ ˈ s iː f , ˈ m æ s ɪ f / )
