Theory of Flexible Systems Managemented to relate their origins to models of modern sedimentary environments and processes. This is a rather crude exercise and refinements are highly desirable. Most of the models of Devonian sedimentary environments must stand or fall not only on the basis of their immediate suitability but also on whe

Time in Question: the Devonian,ndstone, however, was much less certain.

In this chapter we briefly survey some aspects of carbonate and evaporite deposition and their distribution within, and their importance for, the Devonian world (see figure 8.7).

Such is the nature of the crust that it is only in the continental parts that events more than 200 m.y.b.p. or so are recorded. The oceanic realm of earlier days remains more conjectural than does the continental.
