Less than One Percent of the United States Covered by Aeromagnetic Data that Meet Modern Standards

Less than one percent of the United States is mapped by aeromagnetic data that fully meet modern standards and best practices, according to a recent evaluation by the U.S. Geological Survey. Less than five percent of the country has been mapped with data that can be considered adequate in meeting those same standards

Discrete Zr and REE mineralization of the Baerzhe rare-metal deposit, China

Although REE (lanthanides + Y) mineralization in alkaline silicate systems is commonly accompanied with Zr mineralization worldwide, our understanding of the relationship between Zr and REE mineralization is still incomplete (e.g. Škoda and Novák, 2007; Linnen et al., 2014; Petrella et al., 2014; Möller and Williams-Jones, 2016; Wu et al., 2018)....

Alaska Geochemical Database Version 3.0 (AGDB3)—Including “Best Value” Data Compilations for Rock, Sediment, Soil, Mineral, and Concentrate Sample Media

The Alaska Geochemical Database Version 3.0 (AGDB3) contains new geochemical data compilations in which each geologic material sample has one “best value” determination for each analyzed species, greatly improving speed and efficiency of use. Like the Alaska Geochemical Database Version 2.0 before it, the AGDB3 was created and designed to compile...
