Syneclise

A syneclise is a large, relatively shallow depression formed in a continental platform setting, due to slow and steady subsidence.[1] Covering a large area, the slow subsidence generally leads to thick, convergent sedimentary layers with low-angle dips.

Usage

The term is used mostly by Russian and East European geologists. It has been used to describe structures in a wide range of geological settings formed by various processes and has, therefore, lost its usefulness and is falling into disuse.[2] It is often synonymous with the more widespread term basin.[3]

Examples
  • Deccan Syneclise in India[4]
  • Moscow Syneclise in Russia[3]
  • Dneiper-Donetsk Syneclise in Ukraine[3]
  • Pechora Syneclise in Russia[3]
  • Pre-Caspian Syneclise in Russia and Kazakhstan[3]
  • Tunguska Syneclise in Russia[5]
  • Vilyui Syneclise in Russia[5]
