About a third of the approximately 30 known deposits in the Furnace Creek, California, borate district reveal mineralogical zoning of borates. The deposits feature an Na-Ca borate (ulexite and/or probertite) inner zone (or zones) surrounded by Ca bor

In this paper we explore the potential of non-destructive Infrared reflectance microspectroscopy (IRRMS) for the characterization of chert samples from 10 different geological outcrops in North America with emphasis on the Midcontinent. A principle o

The visual and chemical similarity between some chert types and individual outcrops within the same geologic formation often hinders accurate provenance determination. Fourier Transform Infrared reflectance micro-spectroscopy (FTIR-RM) is a nondestru

Laboratory experiments were undertaken to investigate the behaviour of boron at the seawater-air interface during seawater evaporation. Seawaters adjusted to different pH values were heated to 27, 33 and 40 degrees C inside a quartz evaporator. The v

Springs and seeps in the Tecopa basin were sampled and analyzed for their major ion chemistry and oxygen, hydrogen, and boron isotope compositions in order to assess the possible origins of the waters. The Tecopa basin is a groundwater discharge area
