A study of global sand seas
Edwin D. McKee, editor(s)
1979, Professional Paper 1052
The birth of the idea that led to this publication on "Global Sand Seas" dates back to the late 1920's. At that time I was engaged in a study of the Coconino Sandstone of Arizona's Grand Canyon. Considerable controversy existed then as to whether this sandstone was a subaqueous deposit or...

R. E. Rathbun
1979, Water-Resources Investigations Report 79-27
Measuring the reaeration coefficient of a stream with a modified tracer technique has been accomplished by injecting either ethylene or ethylene and propane together and a rhodamine-WT dye solution into the stream. The movement of the tracers through the stream reach after injection is described by a one-dimensional diffusion equation....

1979, Open-File Report 79-1187
A zircon study has been made on 11 samples of igneous rocks from the Saudi Arabian craton. Ages of sized and magnetic fractions of zircon concentrates show variable degrees of discordance, which seem to result from a very young disturbance that produces linear arrays in the Concordia plot. Model age...
