The Stratigraphy of the Upper Part of the Bone Valley Formation and its Relation to the Leached Zone
Description: From abstract: The two topmost zones of the Bone Valley formation at the Homeland mine are a phosphate-cemented quartz sandstone and an underlying pebbly and clayey quartz and phosphate sand characterized by graded bedding. This sequence is found in every other area of the land-pebble field. Therefore, these zones are considered to be stratigraphic units and the transition between them to be a key horizon.
