A theoretical model for the flux of radon from rock to ground water A theoretical model for the flux of radon from rock to ground water
A model is derived to predict the abundance of 222Rn in ground water in contact with a rock of known uranium content. The model assumes that secular equilibrium is attained in the rock-water system as a whole, but is independent of any microscopic geometric properties of the system. The key variables in the model are bulk properties such as porosity, uranium content of the rock...

Crustal structure interpreted from magnetic anomalies Crustal structure interpreted from magnetic anomalies
In this review, we discuss publications during the last quadrennium (1987–1990) that used aeromagnetic data, marine magnetic data, satellite magnetic data, and rock magnetic and petrologic data to provide information on the sources of magnetic anomalies. Abstracts and papers by non‐U.S. authors are not described. The publications reviewed reflect increased integration of rock magnetic...

Late Devonian history of Michigan basin Late Devonian history of Michigan basin
The Upper Devonian sequence in the Michigan Basin is a westward extension of coeval cyclical facies of the Catskill deltaic complex in the Appalachian basin. Both basins and the intervening Findlay arch express the tectonic and sedimentational effects of foreland compression and isostatic compensation produced by the Acadian orogeny. The Late Devonian Michigan Basin formed as one of...

Upper Devonian biostratigraphy of Michigan Basin Upper Devonian biostratigraphy of Michigan Basin
The Late Devonian Michigan Basin was floored by the Middle and Upper Devonian Squaw Bay Limestone, which was deposited during the downwarping that produced the basin within a former Middle Devonian carbonate platform. The Squaw Bay comprises three beds, each having a different conodont fauna. The two upper beds, deposited during the transitans Zone, have different conodont biofacies that...
