- Coals of Chile
- From Introduction: "The purpose of this investigation was to determine whether the coal from beds mined in the Schwager and Lota mines will produce metallurgical coke suitable for use in the blast furnaces at the proposed steel plant at Conception, and whether the quality of the lower-rank coals from other areas in Chile, especially those in Magallanes, where the large coal reserves of Chile appear to exist; can be improved by processing."
- United States Earthquakes, 1952
- Report discussing earthquake activity in the United States during 1952. The report is broken down by regions and has sections for specific earthquakes.
- Reconnaissance for Uranium in the Mamiña Area, Province of Tarapacá, Chile
- Abstract: In 1958 geologists of the U.S. Atomic Energy Commission and the Instituto de Investigaciones Geológicas de Chile made a reconnaissance for uranium in the Mamiña area, Province of Tarapacá in northern Chile.
- Reconnaissance for Uranium in the Elqui-Vicuña area, Province of Coquimbo, Chile
- Abstract: The Elqui-Vicuna area, Coquimbo province, Chile, was selected for uranium reconnaissance on the basis of two known uranium occurrences and favorable area-wide geologic indications of the possible presence of uranium in commercial quantities.
- Reconnaissance for Uranium in the Antofagasta Area, Province of Antofagasta, Chile
- Abstract: The Antofagasta area, in the Province of Antofagasta, Chile, was investigated in September and August 1958 by two field parties of the U.S. Atomic Energy Commission and the Instituto de Investigaciones Geológicas de Chile, who were working under a cooperative agreement between the teo governments. the purpose of the investigation was to examine the area for the possible occurrence of commercial deposits of uranium.
- Reconnaissance for Uranium in the Copiapo Area, Province of Atacama, Chile
- Abstract: The area was examined for a period of about two weeks during October and November 1958 by geologists of the U.S. Atomic Energy Commission and the Instituto de Investigaciones Geológicas de Chile for the purpose of evaluating known uranium occurrences and determining the overall potential of the region for uranium.
- Reconnaissance for Uranium in the Chanaral-Taltal area, Provinces of Antofagasta and Atacama, Chile
- Abstract: In the Chañaral-Taltal area of northern Chile irregular replacement type iron deposits are especially well developed along a somewhat radioactive lithologic belt in andesite volcanic rocks and Cretaceous dioretic intrusions to the east of the Atacama fault, a prominent shear zone.
- Reconnaissance for Uranium in the Arica Area, Province of Tarapaca, Chile
- Abstract: In August 1958 two geologists of the Instituto de Investigaciones Geológicas de Chile made a one-week reconnaissance for uranium of the Arica area in northern Chile.
- Reconnaissance for Uranium in the San Pedro de Atacama and Laco areas, Province of Antofagasta, Chile
- Abstract: A reconnaissance for uranium in and a general geologic study of the San Pedro de Atacama and Laco areas of nothern Chile disclosed no significant radioactivity in the Laco area, but near San Pedro de Atacama slight anomalies were detected in limey silts of the San Pedro formation.
- Reconnaissance for Uranium in the Iquique Area, Province of Tarapaca, Chile
- Introduction: This exploratory work was undertaken as a preliminary evaluation of the area's uranium potential, and was limited to reconnaissance for favorable geologic indications of uranium, which included visits to selected localities and mining districts.
- Reconnaissance for Uranium in the Tocopilla area, Province of Antofagasta, Chile
- Abstract: In September-October 1958 a six-day reconnaissance in the Tocopilla area, Antofagasta Province, Chile, was made by members of the U.S. Atomic Energy Commission and the Instituto de Investigaciones Geológicas de Chile for the purpose of evaluating reported uranium occurrences.
- Reconnaissance for Uranium in the Lonquimay Area, Province of Malleco, Chile
- Discussing a two-week reconnaissance of the Lonquimay area, in south-central Chile, in which anomalies were noted in marl and in a sulfide-mineralized shear zone in continental black shales
- Reconnaissance for Uranium in the Aisen Area, Province of Aisen, Chile
- Discussing a general reconnaissance for uranium in the Aisen area of southern Chile.
- Reconnaissance for Uranium in the Colimapu Formation, Chile
- Discussing Laboratory and field studies that show that the geologic history and environment of the Colimapu formation of central Chile differed considerably from those of the uranium-bearing Diamantiano formation of Argentina with which the Upper Colimapu has been correlated.
