Metal in Ureilites: Siderophile Elements from La-icp-ms
Introduction: Bulk ureilites have near chondritic abundances of siderophile elements [1-7], showing no correlation with Fe contents (~5-16 wt.%) or mg (molar Mg/[Mg+Fe]). These observations are difficult to reconcile with any igneous model for their silicates [8]. We address this problem through detailed characterization of the metal phases in ureilites [9], and petrologic modelling [10]. Here ...
متن کاملUpdated streamflow reconstructions for the Upper Colorado River Basin
[1] Updated proxy reconstructions of water year (October–September) streamflow for four key gauges in the Upper Colorado River Basin were generated using an expanded tree ring network and longer calibration records than in previous efforts. Reconstructed gauges include the Green River at Green River, Utah; Colorado near Cisco, Utah; San Juan near Bluff, Utah; and Colorado at Lees Ferry, Arizona...

متن کاملNest Success of Gunnison Sage-Grouse in Colorado, USA
Gunnison Sage-Grouse (Centrocercus minimus) is a species of concern for which little demographic information exists. To help fill this information gap, we investigated factors affecting nest success in two populations of Gunnison Sage-Grouse. We assessed the relative effects of (1) vegetation characteristics (e.g., shrub height, shrub cover, grass cover, and grass height), (2) temporal factors ...
متن کاملAnalysis of trace metals in comparison of laser-induced breakdown spectroscopy with LA-ICP-MS
Laser-induced breakdown spectroscopy (LIBS) and LA-ICP-MS (laser ablation inductively coupled plasma mass-spectrometry) were used for the detection of trace metals in a solid matrix consisting of KBr and two oxides. The results of both methods were compared to investigate the strengths and weaknesses of both methods. Most difficulties for quantification of LIBS data are related to matrix effect...
