Composition and origin of phosphorite deposits of the Blake Plateau

An area of about 22 000 km2 on the N Blake Plateau contains an estimated 2 billion tonnes of phosphorite concretions, and about 1.2 billion tonnes of mixed ferromanganese-phosphorite pavement. The phosphorite consists primarily of carbonate-fluorapatite, some calcite, minor quartz and other minerals. Drilling and other evidence show that the phosphorite is a lag derived from Miocene strata correla

Within this succession, three lithotectonic units, or sequences of rock that were deformed semi-independently of each other, have somewhat different structural characteristics. Both the Alleghenian and Taconic orogenies have left

Lateral trends and vertical sequences in estuarine sediments, Willapa Bay, Washington

Willapa Bay is a sizable estuary on the southern coast of Washington- Relatively unmodified in a geologic sense by human activity the bay provides an excellent example of modern depositional facies in an estuarine setting. Studies of these deposits indicate that consistent lateral trends exist in sediment texture and sedimentary structures. The texture changes from sandy at the mouth of the bay to
