Excerpt from Stratigraphy, Structure and Phosphate Deposits of the Pungo River Formation of North Carolina The phosphorites of the Pungo River Formation were deposited in a restricted marine basin which had open seaward access to a southward-flowing cool - water cur rent. Structural features that produced this restriction were: (1) north-south trending hinge lines which bor dered the basin of phosphate deposition to the east and to the west, and (2) east to northeast-trending structural noses which formed the northern and ...

Excerpt from Stratigraphy, Structure and Phosphate Deposits of the Pungo River Formation of North Carolina The phosphorites of the Pungo River Formation were deposited in a restricted marine basin which had open seaward access to a southward-flowing cool - water cur rent. Structural features that produced this restriction were: (1) north-south trending hinge lines which bor dered the basin of phosphate deposition to the east and to the west, and (2) east to northeast-trending structural noses which formed the northern and southern bound aries of the basin (fig. The depth of water in the area of phosphate accumula tion, as interpreted from foraminifera, was about 100 to 200 meters. The clastic sedimentation rate was low to moderate, and phosphate deposition probably took place slowly. Abundant life was present, chiefly as planktonic and nektonic forms. The rare remains of normal marine benthos show that the bottom waters were periodically non - toxic. The ph of these waters varied from near to more than as shown by the deposition of both phosphate and calcite.
