Cyclic Deposition of Neogene Phosphorites in the Aurora Area, North Carolina, and their Possible Relationship to Global Sea-Level Fluctuations
The Neogene phosphorites in the Aurora Area occur within the Miocene Pungo River Formation (units A, B, C, and D) and the Pliocene Yorktown Formation (lower and upper units). These units are characterized by the following ...
Stratigraphy and Petrology of the Pungo River Formation, Central Coastal Plain of North Carolina
Up to 30 m of phosphatic sediments of early and middle Miocene Pungo River Formation were deposited in the north-south-trending Aurora Embayment of North Carolina. These sediments thin to approximately 10 to 15 m over the ...
Synthesis of Phosphatic Sediment-Faunal Relationships Within the Pungo River Formation: Paleoenvironmental Implications
The lower part of the Pungo River Formation in the Aurora Embayment (units A and B) consists of phosphorite sands and interbedded dolomites that grade southward into calcareous quartz sand (unit CC) associated with a ...
