SUMMARY OF THE AIRBORNE RADIOMETRIC SURVEY OF THE SOUTHERN CALIFORNIA PROJECT, SOUTHEASTERN CALIFORNIA AND SOUTHWESTERN ARIZONA

摘要

In 1955-1956, six months of airborne operation were required to radio-metrically survey the Southern California project. This project area is located in -southeastern California and southwestern Arizona. Precambrian schists, gneiss, granite;Paleozoic sediments and metasediments;Mesozoic intrusives, metasediments;and Tertiary sediments and volcanics constitute the rock types flown. A total of l42 hours and 20 minutes of rim flying was conducted during which 24 anomalies were detected. Of these anomalies six carry uranium minerals but occurred on claimed ground at the time of this survey. Eleven of the 24 anomalies also occurred on claimed ground but were not ground checked for uranium minerals. Seven anomalies occur on public domain but ground investigations failed to reveal any uranium minerals on the most promising of them. None of these anomalies were posted for public inspection. A 135-horsepower, 2-place, fixed-wing airplane equipped with an airborne scintillation counter was used in this survey.
