The ages of igneous and metamorphic rocks in the New York City area were determined by isotopic techniques. All analyses were made by isotope dilution and mass spectrometric methods. From the data it was concluded that the metamorphism of the New Jer

Theory and prototype (at wavelength lambda = 5 mm) partial coherence scattering data for optical applications in diagnostic measurements on two component suspensions or gases are presented. Results are given for equal volume mixtures of two sizes of

The propagation of lower hybrid waves in the presence of strong density and field gradient-produced refractive effects is studied in the geometric optics limit. Attention is focused on the electrostatic wave and the modification of the parallel waven

Five years after the first publication of age measurements by the radiocarbon method (Arnold and Libby 1951) the method has been established as a powerful technique in the study of archaeology. Lists of radiocarbon dates have been published by a numb

Isotope dilution analyses for He, U, and Th have been performed on magnetite and pyrite samples from the Cornwall, Pennsylvania magnetite deposits. If the extra-lattice U and Th are removed by leaching, the method gives an age for the ore of 194+ or
