The Turle Lake quadrangle is in northeastern Washington about twenty-five miles west of Spokane. The present study includes slightly more than the southern half of the quadrangle. This study is the first detailed study of the rocks in this vicinity; earlier work in the area consists of reconnaissance mapping north...
Impact mechanics at Meteor Crater, Arizona
Eugene Merle Shoemaker
1959, Open-File Report 59-108
Meteor Crator is a bowl-shaped depression encompassed by a rim composed chiefly of debris stacked in layers of different composition. Original bedrock stratigraphy is preserved, inverted, in the debris. The debris rests on older disturbed strata, which are turned up at moderate to steep angles in the wall of the...
Geology of the upper Killik-Itkillik region, Alaska

1959, Open-File Report 59-92
The upper Killik-Itkillik map area is a 2,500 square mile segment of foothills along the north front of the Brooks Range on the Arctic Slope of Alaska. The rocks exposed in this area include eleven formations of sedimentary rocks, three types of surficial deposits, and one igneous rock unit. The...
Geology of the State of Morelos and contiguous areas in south-central Mexico
Carl F. Fries
1959, Open-File Report 59-41
The area described lies in south-central Mexico and embraces all but the southeastern corner and easternmost border of the State of Moreles, the second smallest State in the Mexican Republic.

Frost heaving of piles with examples from Fairbanks, Alaska
Troy Lewis Pewe, R.A. Paige
1959, Open-File Report 60-111
Seasonal freezing of the ground is common throughout most of the world's land surface. As the ground freezes the surface of the ground may rise--this rising is termed frost heaving. Upward displacement of the ground upon freezing is not due alone to the freezing of water originally contained in the...
Occurrences of alunite, pyrophyllite, and clays in the Cerro La Tiza area, Puerto Rico
Fred Adelbert Hildebrand, Raymond J. Smith
1959, Open-File Report 59-54
A deposit of hydrothermally altered rocks in the Cerro La Tiza area located between the towns of Comerio and Aguas Buenas, approximately 25 kilometers southwest of San Juan, Puerto Rico, was mapped and studied to determine the principal minerals, their extent distribution and origin, and the possibility of their economic...
A field method of spectrographic analysis for use in geochemical exploration work
Uteana Oda, A.T. Myers, E.F. Cooley
1959, Open-File Report 59-91
The method to be described is a modification of an earlier method of semiquantitative procedure. Through its use 34 elements can be determined simultaneously in one sample, which may be a rock, soil, mineral, or an ore. For many of these elements concentration ranges from one to ten thousand parts...
