The Ar/Ar data and the Pb, Sr, and Nd data are for basalt and trachyte lava flows at Quetrupilla\u0301n volcano. The Ar geochronology and isotope geochemistry will aid in the understanding of the timing of eruptive activity and glacial damming of lava flows, and magma source compositions studied in the planned publications. Samples were collected from Quetrupill\u00e1n volcano by Dave McGarvie (Univ. of Lancaster, UK) and Isla Simmons (Univ. of Edinburgh, UK), who sent them to the USGS Denver for analysis.
