Geochemistry of bed and suspended sediment in the Mississippi river system: provenance versus weathering and winnowing
Autor: Howard E. Taylor, David Z. Piper, J.S. Duval, Stephen Ludington
Publikováno v: The Science of the total environment. 362(1-3)
Stream-bed sediment for the size fraction less than 150 microm, examined in 14,000 samples collected mostly from minor tributaries to the major rivers throughout the Mississippi River drainage system, is composed of 5 mineral fractions identified by

Mineral resources of the Lime Canyon Wilderness Study Area, Clark County, Nevada
Autor: James George Evans, J.S. Duval, G.A. Nowlan, R.A. Winters
This paper reports on Lime Canyon Wilderness Study Area underlain by Proterozic granite and gneiss that is partly covered by Paleozoic, Mesozoic, and Tertiary sedimentary rocks and by Tertiary and Quaternary alluvium. The study area has an identified

Mineral resources of the Notch Peak Wilderness Study Area, Millard County, Utah
Autor: David R. Zimbelman, W. Lundby, David L. Campbell, D.W. Brickley, K.L. Cook, J.S. Duval, V. Labson, M.H. Podwysocki, D.B. Stoeser
The study area in this report is underlain by a large Jurassic granite that intrudes gently dipping Cambrian and Ordovician limestone and shale. The northern part of the study area includes part of the Notch Peak mining district which has produced tu

Cross sections and complex phase shifts for the scattering of protons from 12C at the 8.20 MeV and 9.14 MeV anomalies
Autor: A.C.L. Barnard, J.B. Swint, J.S. Duval, Thomas B Clegg
Publikováno v: Nuclear Physics A. 93:177-189
Absolute differential cross sections as a function of angle for the elastic scattering of protons from 12 C and for the inelastic scattering reaction 12 C(p, p′) 12 C ∗ ( Q = −4.43 MeV) were measured at incident proton energies of 8.20 MeV and

The behaviour of the complex phase shifts over the 5.3 MeV anomaly in 12C(p, p)12C
Autor: A.C.L. Barnard, J.S. Duval, J.B. Swint
Publikováno v: Nuclear Physics A. 93:164-176
The elastic scattering of protons from carbon in the neighbourhood of the 5.3 MeV anomaly has been investigated using a tandem Van de Graaff accelerator and a differentially-pumped gas scattering chamber. Absolute differential cross sections as a fun
