The Goldfield mining district, Nevada: an acid sulfate bonanza gold deposit The Goldfield mining district, Nevada: an acid sulfate bonanza gold deposit
This paper provides an introduction to the geology, ore deposits, and fluid geochemistry of the Goldfield mining district, Esmerelda and Nye Counties, Nevada. Also included is a brief interpretation of mineral maps of the western half of the district which were recently produced from remotely sensed imagery acquired by the Airborne Visible Infrared Imaging Spectrometer (AVIRIS) systems...

Dams built on pre-existing landslides Dams built on pre-existing landslides
In this paper I summarize the results of a worldwide study of 167 dams that have been constructed on preexisting landslides. Many major landslides in the past have blocked, or partially blocked, river valleys, providing possible dam sites that at first sight have appeared to be ideal. Thus, dams were occasionally built on landslides without a complete understanding of the problems...

Understanding aquatic animal virus survival and trafficking and its role in risk assessment Understanding aquatic animal virus survival and trafficking and its role in risk assessment
The stability of infectious agents in different media and under different physical and chemical environments has been extensively studied for some viruses and virtually ignored for others. Gaps in our knowledge are due in part to difficulties in reproducing virus «life cycles» and determination if the agent is in fact inactive. Additionally, isolation of the agent under certain...

Late-stage development of the Bryant Canyon turbidite pathway on the Louisiana continental slope Late-stage development of the Bryant Canyon turbidite pathway on the Louisiana continental slope
GLORIA sidescan imagery, multibeam bathymetry, seismic profiles, and piston cores (3–5 m penetration) reveal the near-surface geology of the Bryant Canyon turbidite pathway on the continental margin of Louisiana. This pathway extends from the continental shelf edge, across the continental slope, to a deep-sea fan on the continental rise. The pathway is narrow (
