Age of biostratigraphic horizons within the Ordovician and Silurian systems
Michael J. Kunk, J. Sutter, J. D. Obradovich, Marvin A. Lanphere
1985, Geological Society Memoir (10) 89-92
Three samples that have a bearing on the age of horizons within the Ordovician and Silurian systems, two previously dated by the conventional K-Ar method and one by the 40Ar/39 Ar total-fusion method, have been reanalysed using the 40Ar/39Ar age-spectrum method. Conventional K-Ar and total-fusion 40Ar/39Ar ages can always be questioned because of the...

Susan K. Jenson
1985, Conference Paper, Auto-Carto VII: Proceedings of the digital representations of spatial knowledge
Digital elevation model (DEM) data in a raster format can be used to automatically derive the drainage characteristics of an area. A procedure has been designed that is capable of operating on matrices of elevation data having no algorithmically imposed size limit, while performing within the resolution and accuracy tolerances...

The purpose of this study was to develop a methodology to be used to investigate the aquifer characteristics and water supply potential of an aquifer system. In particular, the geohydrology of northern Long Valley, New Jersey, was investigated. Geohydrologic data were collected and analyzed to characterize the site. Analysis was...
Determining age and sex of American coots
William R. Eddleman, Fritz L. Knopf
1985, Journal of Field Ornithology (56) 41-55
Reliable techniques for age and sex determination of migrating and wintering American Coots (Fulica americana) have not been available. Breeding coots can be ages through age 3 by tarsal color (birds 4 years and older were placed in a 4+ age class) (Crawford 1978), and males and females have...
A relational approach to vector data structure conversion
Jan W. van Roessel, Eugene A. Fosnight
1985, Conference Paper, Auto-Carto VII: Proceedings of the digital representations of spatial knowledge
The proliferation of geographic information systems and digital data bases is creating a need for efficient methods to convert data from one spatial data structure to another. One approach is to create ad hoc interfaces, with a potential of N(N-1) interfaces for N data structures. Using an intermediate data structure,...
On the interpretation of satellite-derived gravity and magnetic data for studies of crustal geology and metallogenesis
David A. Hastings
1985, Conference Paper, Geopotential Research Mission (GRM): Proceedings of a conference
Satellite-derived global gravity and magnetic maps have been shown to be useful in large-scale studies of the Earth's crust, despite the relative infancy of such studies. Numerous authors have made spatial associations of gravity or magnetic anomalies with geological provinces. Gravimetric interpretations are often made in terms of isostasy, regional...

R.M. Hirsch, E.J. Gilroy
1985, Journal of the American Water Resources Association (21) 773-784
A method is presented to assist policy makers in determining the combination of number of sampling stations and number of years of sampling necessary to state with a given probability that a step reduction in atmospheric deposition rates of a given magnitude has occurred at a pre-specified time. This pre-specified...

Rate and depth of pedogenic-carbonate accumulation in soils: Formation and testing of a compartment model.
Leslie D. McFadden, John Tinsley
1985, GSA Special Papers (203) 23-41
The rate and depth of pedogenic carbonate accumulation in soils formed in Quaternary alluvium may be viewed as a theoretical problem that involves the mutual interaction of several independent and dependent soil-forming variables. We propose a model for carbonate accumulation in which the soil column is defined by a vertical...
