THE NATURE AND HYDROGEOLOGIC SIGNIFICANCE OF MUD DIAPIRS AND DIATREMES FOR ACCRETIONARY SYSTEMS

The nature of fluid input from local and exotic source regions can strongly affect sedimentary intrusive processes and vice versa. This complicates the process of defining the main features of the hydrogeological systems operating in accretionary wedges. When active, large diatremes require enormous quantities of fluid (water or gas) to drive them particularly if they are long lived features and hence are a direct indication of at least an episodically vigorous hydrogeologic system. -from Author
