Coronadite — Modes of occurrence and origin
D. F. Hewett
1971, Economic Geology (66) 164-177
The lead manganate, "coronadite," was first recognized at the Coronado mine in the Morenci district, Arizona, by Lindgren in 1903. Several years later, the identity of the mineral was questioned and it was not until 1932 that Orcel recognized it in material from Morocco. Since...

Gold is present in weathered wall rock and quartz veins of the opencut of the Calhoun mine, Lumpkin County, Georgia. Eleven samples of mica schist saprolite contain 0.02 to 0.1 parts per million (ppm) gold and three samples of weathered vein quartz, 0.04 to 0.6...
Application of an acoustic streamflow-measuring system on the Columbia River at The Dalles, Oregon
Winchell Smith
1971, Journal of the American Water Resources Association (7) 69-78
The need for accurate, independent records of flow on the Columbia River at The Dalles, Oregon, has been met by the installation of an acoustic streamflow-measuring system. This device provides an index of the velocity of flow by...
Surf-beat origin for pulsating bottom currents in the Rio Balsas submarine canyon, Mexico
Erk Reimnitz
1971, Bulletin of the Geological Society of America (82) 81-89
A previously unreported process was observed at the head of a tributary to the Rio Balsas submarine canyon system in Mexico. During a period of large surf, river discharge deflected a pulsating longshore current [peaking at over 7 km/hr (2 m/sec)] seaward over the tributary...
Floods in the Wapsipinicon River Basin, Iowa
Harlan H. Schwob
1971, Report
Flood information is reported for 338 miles of the main stem and six tributaries of the Wapsipinicon River. The information will be of use to those concerned with the design of bridges and other structures and the conduct of various operations on the flood plains of the streams. Included in...
An evaluation of procedures used in computing chemical denudation rates
Richard J. Janda
1971, Bulletin of the Geological Society of America (82) 67-79
Computations of chemical denudation rates (that is, the average rate of lowering of the earth's crust by chemical processes) should be based only upon those components of dissolved loads of streams that are derived from chemical weathering of rocks and soils, even though identification of those components is difficult and...
Minor elements in water

Groundwater Recharge Conference Reading, England September 21-24, 1970
Richard T. Sniegocki
1971, Eos Science News (52) 26-26
An international Conference on Artificial Groundwater Recharge was held at the University of Reading, Whiteknights Park, Reading, Berkshire, England, sponsored by the Water Research Association, Medmenham, Marlow, Buckinghamshire. One hundred sixty-one delegates, representing 20 countries, registered. Five excellent tours...
Recharge characteristics of a watercourse aquifer system at Springfield, Ohio
Stanley E. Norris, Herbert B. Eagon Jr.
1971, Groundwater (9) 30-41
An investigation was made of infiltration conditions in the alluvial-filled Mad River valley in the vicinity of the Springfield municipal wells. The study shows that most recharge to the 100-foot thick sand and gravel aquifer is from induced infiltration from the Mad River. Local precipitation and natural, down-valley underflow also...

1971, Iowa Geological Survey Water Atlas 4
Water is vital in the lives of the people and the economy of any area. In order to utilize this natural resource in the most efficient and beneficial manner, a basic knowledge and understanding of its sources and the occurrence and potential of each source must be gained. To provide...

Chemical compositions of rock types as factors in our environment
Harry A. Tourtelot
Helen L. Cannon, Howard C. Hopps, editor(s)
1971, Book chapter, Environmental geochemistry in health and disease
The types of rocks that form geologic units in the Earth’s crust supply most of the raw materials from which soils are formed and from which water derives its inorganic constituents. The compositions of what we eat and drink thus depend in part upon the compositions of the source rocks.Igneous...

Wells and springs in California and Nevada within 100 miles of point 37°15' N, 116°25' W, on Nevada test site
William Thordarson, B.P. Robinson
1971, Report
Studies of published and unpublished geologic and ground-water data, for an inventory of 6,032 wells and 754 springs in parts of Inyo and Mono Counties, California, and Clark, Esmeralda, Lincoln, and Nye Counties, Nevada, reveal the following information:A complex sequence of granitic, metamorphic, volcanic, and sedimentary rocks of Precambrian to...
Water resources of the Coamo area, Puerto Rico
Ennio V. Giusti
1971, Report
This study, like other similar studies, was made possible by a cooperative water-resources program between the U.S. Geological Survey and the Puerto Rico Water Resources Authority (at the time), representing also the Puerto Rico Aqueduct & Sewer Authority and the Puerto Rico Industrial Development Company.This report covers the hydrologic investigation...
Open-channel integrating-type flow meter
K.C. Koopman
1971, Report
A relatively inexpensive meter for measuring cumulative flow in open channels with a rated control,. called a "totalizer", was developed. It translates the nonlinear function of gage height to flow by use of a cam and a float. A variable resistance element in an electronic circuit is controlled by the...
