[PAR] [TLE] Geosyncline [SEP] Geosyncline is a geological concept which was developed in the late 19th and early 20th centuries before the concept of plate tectonics was developed.  A geosyncline was described as a subsiding linear trough that was caused by the accumulation of sedimentary rock strata deposited in a basin and subsequently compressed, deformed, and uplifted into a mountain range, with attendant volcanism and plutonism.  The filling of a geosyncline with sediment is accompanied in the late stages of deposition by folding, crumpling, and faulting of the deposits.  Intrusion of crystalline igneous rock and regional uplift along the axis of the trough generally complete the history of a particular geosyncline.  It is then transformed into a belt of folded mountains.  Thick volcanic sequences, together with greywackes (sandstones rich in rock fragments with a muddy matrix), cherts, and various sediments reflecting deepwater deposition or processes, were considered "eugeosynclinal" deposits of the outer deepwater segment of geosynclines. [PAR] [TLE] Samfrau Orogeny [SEP] The Samfrau Geosyncline or Samfrau Orogeny is an orogenic belt that was active in the Palaeozoic and early Mesozoic in Gondwanaland, formed by small terranes and deep accumulations of old sediment dumped off the continent's edge by erosion, acccreting against the Pacific-side coast of Gondwanaland due to subduction.  Its name (as "Samfrau Geosyncline") was coined by Alexander du Toit.  Parts of it exist now in northern Argentina, South Africa, Antarctica, and part of the east coast region of Australia, as shown in the map at this link.
