Geosyncline - Wikipedia
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.
Geosynclinal Theory - University of Illinois Urbana-Champaign
Geosynclines are further classified into miogeosynclines, eugeosynclines, and orthogeosynclines; dependent on rock strata, location, and nature of the mountain system. A miogeosyncline forms along the passive margin of a continent and is comprised of sandstones, limestones, and shales (Continental Drift).
Geosynclines and geoclines - SpringerLink
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.
Geosyncline | Orogeny, Sedimentation & Subduction | Britannica
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 …
Geosyncline - an overview | ScienceDirect Topics
A 'geosyncline' refers to a large accumulation of sediments and sedimentary rocks in a continental margin or basin, often incorrectly referred to as a syncline, that plays a significant role in the geological history of a region.
10.2: Global Geological Models of the Early 20th Century
2024年4月24日 · Geosynclinal sediments—which eventually turn into sedimentary rocks—may be many thousands of meters thick. As they accumulate, they push down the pre-existing crustal rocks. Extensive geosynclinal deposits exist around much of the coastline of most of the continents; there is a large geosyncline along the eastern edge of North America.
Basic principles of the geosynclinal theory - ScienceDirect
1970年1月1日 · The geosynclinal system (geosyncline) is the aggregate of alternating rises (elementary geanticlines) and saggings (elementary geosynclines), within which the geosynclinal process is realized. The geosynclinal theory deals only with the geosynclinal stage of the earth's crust development.

2021年12月21日 · The studies conducted during the second phase of the 20th century reveal that a geosyncline is a thick, rapidly accumulating body that lies parallel to the continent. The age-old idea of a geosyncline or an intra-cratonic trough bordered by mountains contributing sediments needs to be abandoned.
Geosynclines: Features, Concept and Stages | Geology
On an average, a geosyncline means a water depression characterized by sedimentation. It has now been accepted by majority of the geologists and geographers that all the mountains have come out of the geosynclines and the rocks of the mountains originated as sediments were deposited and later on consolidated in sinking seas, now known as ...
HUNDREDTH ANNIVERSARY OF THE GEOSYNCLINCAL THEORY …
2009年9月1日 · During the last 100 years the geosynclinal theory has developed through a number of stages. From 1859 to the nineties of the 19th century it grew out of “infancy” and took on definite form. After M. Bertrand and E. Haug's works, up to the nineteen twenties is a period of general theory of the earth crust development.
