Composition and origin of phosphorite deposits of the Blake Plateau 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...

Geology of the Ridge and Valley Province, northwestern New Jersey and eastern Pennsylvania Geology of the Ridge and Valley Province, northwestern New Jersey and eastern Pennsylvania
The rocks seen in this segment of the field trip range in age from Middle Ordovician to Middle Devonian and constitute a deep basin-continental-shallow shelf succession. 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...

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

Research on interactive genetic-geological models to evaluate favourability for undiscovered uranium resources Research on interactive genetic-geological models to evaluate favourability for undiscovered uranium resources
Current methods of evaluating favourability for undiscovered uranium resources are unduly subjective, quite possibly inconsistent and, as a consequence, of questionable reliability. This research is aimed at reducing the subjectivity and increasing the reliability by designing an improved method that depends largely on geological data and their statistical frequency of occurrence. This...

Electronic and optical modification of the engineering model FLD and the evolution of peripheral equipment Electronic and optical modification of the engineering model FLD and the evolution of peripheral equipment
The purpose of the Workshop on Luminescence Techniques was threefold: (1) to review the state-of-the-art capabilities of luminescence methods, (2) to consider a variety of concepts for the development of future luminescence sensor systems, and (3) to discuss appropriate research and development strategies for advancing the current state-of-the-art.
