For 85 years, ending in 1996, the US Bureau of Mines (USBM) drafted and released 1000s of seminal reports on mineral resources and mining technology in the United States. The contents of those reports still have value. Unfortunately, access to USBM reports frequently proves difficult.
- Wildcat Peak is an ancient volcanic feature largely destroyed by erosion. Miles of resistant N-S feeder dikes still outcrop nicely.
- US Geological Survey's 2019 could be slashed. The result would be a 25% reduction in staff and a marked reduction services in such areas as natural hazard assessment and geologic mapping.
- The catastrophic debris flows that flattened Montecito, CA, are no stranger to Arizona. Just ask the residents below the Schultz Fire zone on the east flanks of Flagstaff's San Francisco Peaks.
- G.E.M. Environmental NFP (not-for-profit) is a fledgling organization whose chief goal is to champion geoscience students and help them gain the industry experience they need to be competitive job seekers.
Gov. Ducey's 2019 fiscal year budget includes a Special Line Appropriation for the Arizona Geological Survey (AZGS) of $941,000 (Table1). Identical to what AZGS received from the state in fiscal year 2018.
- Geology & uranium potential of Proterozoic rocks of the Central Arizona Arch and the Tonto Basin, ArizonaWe are releasing a second suite of Phil Anderson’s geologic mapping and research of Proterozoic rocks, which includes geologic mapping and geochemical sampling of the Central Arizona Arch that covers roughly 3,000 square miles in central Arizona.
- "A Presidential executive order on a federal strategy to ensure secure and reliable supplies of critical minerals, issued December 20, 2017, includes the assertion that the USA is limited by a lack of comprehensive, machine-readable data concerning topographical, geological, and geophysical surveys."
- Oddly enough, Arizona has an earth fissure season; a season when fissures are more likely to first appear or undergo renewed activity. This article showcases revised earth fissure maps for parts of Cochise, Maricopa, and Pinal Counties, as well as case studies of one new (Tator Hills) and one reactivated fissure (Apache Junction). Systematic mapping and observations of the physical conditions of ‘older’ fissures suggests that earth fissure activity in some study areas is waning.
