Summary
|
Abstract:
This dataset contains Neodymium (Nd) and Strontium (Sr) isotopic data from water soluble salts and associated host soils, cobbles, and surface volcanic deposits in the Dry Valleys of Antarctica (samples provided by David Marchant of BU and Huiming Bao of LSU). Also included is data from a single salt and cobble sample from the Siesta paleosol near the Beardmore Glacier (sample provided by Gregory Retallack of Oregon St.). Sr, Nd, and Rb concentrations are also available for most samples. XRD mineralogic identification of salts is available for some samples. All isotopic data were collected by TIMS analysis either at MIT (lab of Sam Bowring) of UC Berkeley (lab of Donald DePaolo). Concentration data were collected by ICP-MS at BU. |
