==Regional climates==

Arid or humid conditions can occur simultaneously in different regions during icehouse or greenhouse periods. The aridity or humidity of a region strongly affects carbonate deposition and [http://wiki.seg.org/wiki/Dictionary:Diagenesis diagenesis]. For example, carbonates deposited under arid conditions tend to be associated with evaporites, and carbonate sequences are partly to completely dolomitized. In humid regions where rainfall is greater, carbonates are subject to greater dissolution; therefore, vuggy porosity and [http://wiki.seg.org/wiki/Dictionary:Karst karst] features are common.
