Summary:

Interbedded black shale carrying Estheria ovata and gray sandstone are here apparently [informally] named the Vinita beds, the lower division of the Chesterfield group. Conformably overlies the productive coal measures of the Tuckahoe group and underlies the Otterdale sandstone of the Chesterfield group. Thickness is 2,000 ft (600 m). Age is Late Triassic.

Summary:

Nomenclature in this report follows Ediger and others (in prep). Richmond basin sequence is divided into three formations (ascending): Tuckahoe, Turkey Branch, and Otterdale Formations of Newark Supergroup. Contacts are unconformable. Tuckahoe Formation is divided into (ascending) Lower Barren Beds Member, Productive Coal Measures Member, and Vinita Beds Member. Lower part of the Vinita Beds Member is dominantly lacustrine, but higher in the member, sediments become deltaic-fluvial in origin. The Vinita correlates with the lower part of the Falling Creek Member of the Doswell Formation in the Taylorsville basin. Age of the Vinita is middle Carnian. . [Member names as used in this report are in violation of the NACSN and though presented as formal, should be considered informal.]
