Techniques for estimating streamflow characteristics in the Eastern and Interior coal provinces of the United States
Techniques are presented for estimating various streamflow characteristics, such as peak flows, mean monthly and annual flows, flow durations, and flow volumes, at ungaged sites on unregulated streams in the Eastern Coal region. Streamflow data and basin characteristics for 629 gaging stations were used to develop multiple-linear-regression equations. Separate equations were developed for the East

Rates of chemical weathering of rocks and minerals
Researchers in geomorphology, geochemistry, quaternary geology, soil science, and mineralogy will welcome this volume, the first to focus exclusively on rates of silicate chemical weathering. Consisting largely of previously unpublished data from six countries, the volume examines the latest experimental, modelling, and field results.New information is presented on topics of current research inter

Mapping nuclear craters on Enewetak Atoll, Marshall Islands
In 1984, the U.S. Geological Survey conducted a detailed geologic analysis of two nuclear test craters at Enewetak Atoll, Marshall Islands, on behalf of the Defense Nuclear Agency. A multidisciplinary task force mapped the morphology, surface character, and subsurface structure of two craters, OAK and KOA. The field mapping techniques include echo sounding, sidescan sonar imaging, single-channel a

A note on the relationships between organic matter and some geotechnical properties of a marine sediment
An analysis of the relationship between organic matter and liquid and plastic limits, and grain‐specific gravity of a marine sediment was accomplished by making a stepwise adjustment in the organic content of that sediment. The sample used was from Santa Barbara Basin (off southern California) and is typical of fine‐grained marine sediments: it is a clayey silt with a common suite of minerals and
Method for estimating low-flow characteristics of ungaged streams in Indiana
Equations for estimating the 7-day, 2-year and 7-day, 10-year low flows at sites on ungaged streams are presented. Regression analysis was used to develop equations relating basin characteristics and low-flow characteristics at 82 gaging stations. Significant basin characteristics in the equations are contributing drainage area and flow-duration ratio, which is the 20-percent flow duration divided

Aluminum in hornblende: an empirical igneous geobarometer.
Electron-microprobe analyses of hornblendes from five calc-alkaline plutonic complexes representing low- and high-pressure regimes define a tightly clustered linear trend in terms of total Al (AlT) and tetrahedral Al (Aliv) contents. Data collated from the literature on calcic amphiboles from other plutonic complexes and from phase equilibrium experiments using natural rocks or synthetic analogue
