    Abstract:
    We present 36 new ⁴⁰Ar-³⁹Ar incremental heating age determinations from the Caribbean Large Igneous Province (CLIP) providing evidence for extended periods of volcanic activity and suggest a new tectonomagmatic model for the province’s timing and construction. These new ⁴⁰Ar-³⁹Ar ages for the Curaçao Lava Formation (CLF) and Haiti’s Dumisseau Formation...

  • Volatile mobility of trace metals in volcanic systems

    Creator:
    Loewen, Matthew W.
    Abstract:
    Semi-volatile trace metals like Li, Cu, Mo, Sn, In, and Pb have the potential to track mobility of a volatile phase in volcanic systems. In this dissertation four studies are presented that either directly investigate or are motivated by observations of trace metal behavior in volcanic systems. A common tool...
