Intercalibration of radiometric and biostratigraphic time                  scales for the early Mesozoic is not well established.                          Uncertainties in absolute age assignments to stage boundaries for               parts of the Triassic and Jurassic may exceed 30 Ma.  This                      proposal seeks support for high-precision zircon U-Pb age dating                of vitric tuff beds that occur within well-preserved fossiliferous              strata of the Murihiku Supergroup of New Zealand.  This thick                   clastic succession comprises mainly marine volcanogenic rocks that              span most of Triassic and Jurassic time and can be correlated to                the international column at key points on the basis of virtually                cosmopolitan ammonoids and pteroid bivalves.  Preliminary zircon                ages from 13 tuff beds spaced through ~6 km of section within the               Middle to Upper Triassic portion of the Murihiku Supergroup range               from 232 to 204 Ma.  On the basis of high-precision Pb/Pb ages                  from step-wise dissolution experiments, the FAD and LAD for                     Monotis are constrained to occur within 226 Ma to 218 Ma.  It is                proposed to complete detailed, comprehensive study of the Middle                and Upper Triassic sections of the Murihiku Supergroup, and                     extending the range of our sampling to include the Lower Triassic               and Jurassic portions of the sequence.  This work, along with                   high-precision dating of granitoid clasts from conglomerates in                 the section, will provide information on sedimentation rates and                cycling rates of material between plutonism-uplift-erosion-                     transport-deposition, and will contribute significantly to                      understanding the dynamics of basin evolution.
