Quick Summary

A taphrogeosyncline is a geological term referring to a depressed block of the Earth's crust. This block is characterized by being bounded by one or more high-angle faults and serves as a location where significant amounts of sediment accumulate.1

The concept of the geosyncline, which includes taphrogeosynclines, was introduced by James Hall in 1859. While many modern geologists prefer explanations based on plate tectonics, the term "geosyncline" and its variations are still sometimes used. Geosynclines are linear troughs where sediments build up over time, eventually leading to folding, faulting, and uplift that can form mountain ranges.1

…common of these are the taphrogeosyncline, a depressed block of the Earth’s crust that is bounded by one or more high-angle faults and that serves as a site of sediment accumulation, and the paraliageosyncline, a deep geosyncline that passes into coastal plains along continental margins.
