During the period 1800-1600 Ma, the North American continent               grew by at least 20%. Amalgamation of these Proterozoic rocks                   into continental crust could have been accomplished in a number                 of ways.  This project will investigate the nature, timing and                  significance of tectonic blocks of early Proterozoic age in                     northern and central New Mexico.  Major shear zones separating                  the blocks will be a focus of research to specify the timing,                   sense of displacement, and pressure-temperature conditions                      across boundaries.  Results are expected to clarify how these                   tectonic blocks were assembled, and with other data, to                         help develop a model of proterozoic accretion for North America.
