This data set provides total element concentration and simulated lung and gastric fluid bioaccessibility from previously collected Uranium mineral deposit samples (1971 and 1981, Southwestern U.S.) exploring possible exposures to other hazardous trace metals. Elevated total as well as simulated gastric and lung fluid concentrations were observed for arsenic, cobalt, manganese, thallium, vanadium and uranium.

Some of the highest grade uranium (U) deposits in the United States are hosted by solution-collapse breccia pipes in the Grand Canyon region of northern Arizona. These structures are named for their vertical, pipe-like shape and the broken rock (breccia) that fills them. Hundreds, perhaps thousands, of these structures exist. Not all of the breccia pipes are mineralized; only a small percentage of the identified breccia pipes are known to contain an economic uranium deposit. An unresolved question is how many undiscovered U-bearing breccia pipes of this type exist in northern Arizona, in the region sometimes referred to as the “Arizona Strip”. Two principal questions remain regarding the breccia pipe U deposits...

This data release is a compilation of six earlier reports on natural occurrences of asbestos in the conterminous United States, which were published separately; these are Van Gosen (2005, 2006, 2007, 2008, 2010) and Van Gosen and Clinkenbeard (2011). The earlier reports were compilations divided by regions of the United States; in each report the data were provided in spreadsheet format. This data release combines the regional datasets into a single compilation for the entire conterminous United States, and includes shapefiles and spreadsheet formats. This data release provides site-by-site information on 876 natural occurrences of asbestos reported within the conterminous United States. This dataset allows the...
