Classification of basins, with special reference to Proterozoic examples

摘要: Abstract Basin classification rests on a plate tectonic foundation, highlighting lithospheric substrate, proximity to margin and relative motion of the nearest boundary. Major mechanisms for regional subsidence uplift are subdivided into isostatic, flexural dynamic groups. Basin-forming basin types do not exhibit simple cause-and-effect relationships, but rather reflect matrix-type relationship. Different have different spans existence, with generally shorter life related more tectonically active settings. Many ‘polyhistory’ basins, composed two or megasequences, long evolution dominated by basin-forming basin-modifying mechanisms. The supercontinent cycle is marked distinct sets types, developed during successive phases cycle. schemes reviewed briefly, before surveying range represented in Proterozoic several key cratonic areas. Basins examined encompass almost entire Neoarchaean–Neoproterozoic period. All these basins relatively history preservation, which can be tied essentially continental character their basement rocks concomitant enhanced ‘survivability’. Their preservation thus underlines longevity inherent stability lithosphere. distinction between occurrence over geological time preferential important when viewing record.
