Abstract

The temperatures and pressures of diagenesis and very low-grade metamorphism of the Palaeozoic formations of the Valley-and-Ridge province in the central Appalachians are revealed by analyzing their fluid inclusions. Samples from two areas were studied and compared: 1) the Silurian and Devonian Delaware Water Gap area and 2) the anthracite region of eastern Pennsylvania. Gaseous CH₄-CO₂ and aqueous (± CH₄) inclusions were studied by microthermometry; gas compositions were measured by Raman analysis. The two fluids are thought to have been immiscible, saturated fluids. -from Authors
