Abstract

Form and his associates have been engaged in an extensive program of recognizing and mapping environments of coal deposition in the Appalachian coal field from Pennsylvania to Alabama. By comparing ancient coal-bearing rocks to modern deposition analogues, a set of criteria has been developed for recognizing environments, ranging from fresh water alluvial plains to tidally influenced marshes and swamps behind beach barriers (“back barrier sediments”). Caruccio has shown that the acidity of mine drainage from strip mines in the bituminous coal field of Pennsylvania is determined to a large extent by three interrelated factors. These include the reactivity of the pyrite found in the coal and the associated strata, the presence of a catalyst (iron bacteria), and the neutralizing capacity of the existing ground water. All these are indigenous to particular sedimentary paleoenvironments that were delineated.within the Carboniferous Allegheny Formation.

A comparison of Caruccio’s and Ferm’s data reveals that the coals rich in reactive pyrite are found in back barrier and lower delta plain deposits, and coals poor in reactive pyrite can be associated with upper delta and alluvial plain settings. Because most Appalachian coal beds are known to represent at least two depositional environments throughout their areal extent and mineable coals are found in all four ma'jor environments., a criterion appears to be available for predicting the areal .distribution of acid mine drainage problems without costly and time-consuming analytical procedures.
