The Quebrada Angosta travertine has its source at 4840 m above sea level on the southern lower slope of the east-trending, narrow Quebrada Angosta valley. There, the bedded, finely laminated, aragonite-calcite travertine has an average dip of 30° and attains a thickness of~2 m. The travertine overlies talus composed of unaltered Agua Amarga andesite, which is also present as fragments in the basal carbonate layer. Carbonate deposition then followed the valley downstream for 1.8 km, giving rise to a more crudely bedded and friable calcite-aragonite deposit, with an average slope of 3 to 5° and thicknesses of up to 2.5 m, overlying as much as 5 m of alluvial gravel, sand, and silt deposited by the Quebrada Angosta stream. Representative chip samples collected recently returned between 0.1 and 2.5% Cu,>1% As in samples with>1% Cu, and up to 9.3 ppm Ag. However, contents of lead (up to 840 ppm) and zinc (up to 665 ppm) are an order of magnitude lower than at La Borita. Quebrada Angosta is a terrace travertine fed from a point source on the steep valley side.
