Abstract

Abstract:

The Devonian and Carboniferous laminated dolomites in GuizhouGuangxi Region are mainly distributed on the edge of continentlinked(shelf)carbonate platform and the isolated carbonate platform near deep trough.The dolomitization mechanism includes active tidal pumping dolomitization ,normal seawater dolomitization,mixed near surface dolomitization,buried squeezecompaction flow dolomitization, tectonic hydrothermal dolomitization.It is suggested that different dolomitization models possess different mechanisms and characters.

Key words: dolomitization, model, continentlinked carbonate platform, isolated carbonate platform intraplatform sag, reservoir quality
