BOGS A WEB PRESENTATIONEmporia State University
Sphagnum grows at the surface and dies at the bottom therefore it is a steady contributor to peat formation (Damman and French 1987). Peat can be classified on the type of plant material from which it was derived. Damman and French (1987) recognize five types of peat based on their vegetal origin. The types of peat are

Peat forms when plant material accumulates in an anoxic environment where decay is inhibited. Typically this is in marshes and bogs associated with deltas flood plains tidal marshes etc. If it becomes progressively buried and heated it can eventually turn into bituminous coal

The objective of this paper is to evaluate allocyclic and autocyclic controls on sedimentation in an epeiric setting in a humid (ever-wet) tropical region. Of particular interest are the factors that control peat formation and siliciclastic sediment flux in rivers estuaries and open marine environments.
