Platinum deposits of the Goodnews Bay district, Alaska
John Beaver Mertie Jr.
1976, Professional Paper 938
Platinum placers were discovered in 1926 in a small area south of Goodnews Bay, in southwestern Alaska. Beginning in 1927, the placers were worked for 7 years by small-scale mining methods; in later years dragline excavators and a dredge were utilized. These deposits are important, not only because they are...

Bicarbonate content of groundwater in carbonate rock in eastern North America
F.W. Trainer, R.C. Heath
1976, Journal of Hydrology (31) 37-55
In carbonate-rock terrane the most effective solution occurs where soil and vegetative cover facilitate biogenic production and storage of CO2 in the soil until part of it is carried downward in percolating water. Bicarbonate data for groundwater in eastern North America are examined in the light of these conditions, of...
