A geosyncline (originally called a geosynclinal) is an obsolete geological concept to explain orogens, which was developed in the late 19th and early 20th centuries, before the theory of plate tectonics was envisaged. [1][2] A geosyncline was described as a giant downward fold in the Earth's crust, with associated upward folds called ...

Geosyclinal theory can be divided into two main stages. The first involves major sediment deposition (651). Following this is an event called the mountain making “crisis,” which is very quick relative to the first stage (651).

Geosyncline, linear trough of subsidence of the Earth’s crust within which vast amounts of sediment accumulate. The filling of a geosyncline with thousands or tens of thousands of feet of sediment is accompanied in the late stages of deposition by …

These mobile zones of water have been termed ‘geosynclines’ which have now been converted by compressive forces into folded mountain ranges. On an average, a geosyncline means a water depression characterized by sedimentation.

2023年3月21日 · Geosynclines are elongated basins of sedimentary rock that form in tectonically active regions. They are often located between continents or island arcs and are characterized …

2024年8月13日 · Geosynclines are significant structural depressions in the Earth’s crust, often associated with the formation of mountain ranges and the evolution of the planet’s surface.

A geosyncline is a very elongated structural trough in which a great thickness of sedimentary and/or volcanic rock has been deposited. Hall (1859) observed that the Paleozoic sedimentary sequences in New York State show a systematic thickening from west to east across the state.

2021年12月21日 · Such a thick column of sediment along the border of a passive margin is called geosyncline. The studies conducted during the second phase of the 20th century reveal that a …

1970年1月1日 · The gsynclinal system (geosyncline) is the aggregate of alternating rises (elementary geanticlines) and saggings (elementary geosynclines), within which the gsynclinal process is realized.

A geosyncline is a thick deposit of sediments and sedimentary rocks, typically situated along the edge of a continent (Figure 10.2.1 10.2. 1). Figure 10.2.1 10.2. 1 The development of a geosyncline along a continental margin.
