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
A miogeosyncline forms along the passive margin of a continent and is comprised of sandstones, limestones, and shales (Continental Drift). Eugeosynclines are composed of thick sequences of deep marine sediments; they are often more deformed and metamorphosed (Continental Drift).
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.

2023年3月21日 · Geosyncline theory, also known as geosynclinal theory or geosynclinal hypothesis, was a scientific theory developed in the late 19th and early 20th centuries to explain the formation of mountain ranges and the distribution of rock formations on the Earth’s surface.
Basic principles of the geosynclinal theory - ScienceDirect
1970年1月1日 · The geosynclinal theory deals only with the geosynclinal stage of the earth's crust development. The important principles of the theory are: 1. (1) the presence of the geosyncline (geosynclinal system); 2. (2) mobility; 3. (3) the inner sources of geosynclinal deposits; 4. (4) large gradients of the deposit of thickness variation; 5.

1972年3月1日 · A geosyncline is a huge deposit of sedimentary rock that forms at the edge of a continent. When it is compressed, it buckles up into a mountain range. It also enables a continent to...
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.

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. These large-scale troughs have played a crucial role in shaping the Earth’s topography, and their study provides valuable insights into the processes that have driven ...

2011年1月1日 · This chapter discusses geosynclines, passive margins, foreland basins, and folded belts. Application of the geosynclinal model provided guidelines for geological exploration and thinking in different fold belts worldwide and particularly those surrounding the Mediterranean.
