| Summary | The Bluefield Formation comprises interbedded shales, limestones and sandstones representing deposition transitional between marine carbonates and shallow marine to deltaic siliclclastics. Bluefield sandstones vary lithologically from relatively coarse-grained, clean, and orthoquartzltic (up to 95.0% quartz) to very fine-grained, matrix and rock fragment-rich (as low as 41.0% quartz) varieties. In this study, sandstones are subdivided into two groups: Type 1, which are very fine-grained and argillaceous; and Type 2, which are coarse-grained, clean, and quartzitic. Diagenetic alteration of Type 1 sandstones was dominated by mechanical compaction. Quartz authigenesis, accompanied by intergranular pressure solution, was the principal diagenetic process in Type 2 sands. Minor secondary porosity is present in Type 1 sands. Type 2 sandstones contain small amounts of both primary and secondary porosity. The lower part of the Bluefield Formation consists of marine limestones, calcareous shales and thin, carbonate-cemented shelf sands deposited in a shallow marine setting. The Droop Sandstone, located approximately at the boundary between the upper and lower Bluefield, was deposited as a prograding barrier island complex. Upper Bluefield strata were deposited in a prograding delta. |
