density and magnetic


This archive contains density and magnetic susceptibility data, and brief synopsis of rock density measurements which were made in Nov.-Dec. 2017 as part of the Fallon FORGE project. Researchers from University of Nevada, Reno measured rock density on core samples obtained from three different wells: 51-20 (~6 km SE of the FORGE site), FOH2 (within the FORGE area), and BCH-3 (at the Bradys geothermal area ~40 km NW of the FORGE site). The subsurface geology at these three wells is similar and consists of Quaternary sediments (QTs) on top, overlying mafic Tertiary volcanic rocks (Tba) which, in turn, overlie a variety of Mesozoic basement rocks (Mz). In the BCH-3 well, a layer of Oligocene-age rhyolitic ignimbrite (Ttr) is sandwiched in between the Tba and Mz rocks. UNR researchers measured grain density, saturated bulk density, and dry bulk density on the core samples from these wells (although in this memo, only saturated bulk density is reported). Densities were measured on the following major rock types encountered in each well: 51-20: only Tba (n = 33). FOH-2: only Tba (n = 172). BCH-3: Tba, Ttr, and Mz (n = 120).
