| dc.description.abstract | <p><span>The timing of critical mineral deposit formation is challenging to determine, particularly in areas with a complex tectono-thermal history. We apply <em>in situ</em> <sup>87</sup>Rb/<sup>87</sup>Sr geochronology to investigate the emplacement timing of the Brazil Lake pegmatite Lithium-Cesium-Tantalum deposit, Nova Scotia, Canada. The novel <em>in situ</em> method for <sup>87</sup>Rb/<sup>87</sup>Sr geochronology is compared with the more established <sup>40</sup>Ar/<sup>39</sup>Ar method. Six mica types were identified in and around the pegmatite. Geochronology of the pegmatite is dictated by the initial mineralization age, determined from the oldest <sup>87</sup>Rb/<sup>87</sup>Sr date of 390.9±1 Ma, and the maximum resetting/re-equilibration age ca. 330-320 Ma. Quartz-hosted fluid inclusions indicate post-solidus temperatures were sufficient to reset <sup>40</sup>Ar/<sup>39</sup>Ar, but not <sup>87</sup>Rb/<sup>87</sup>Sr systematics. Re-equilibration was driven by a combined thermal-fluid event recognized in the BLP and southern Nova Scotia.</span></p> | en_CA |
