Rapid Uplift

Apatite and zircon fission-track data from the Nelson batholith in southeastern British Columbia reveal that a significant amount of uplift has occurred since Paleocene time, including an episode of rapid uplift during Eocene time. Age versus elevation curves for apatite and zircon, combined with a calculated present depth to the 105 °C apatite-annealing isotherm, suggest that some 6 km of apparent uplift has occurred in the vicinity of the Nelson batholith since Paleocene time. A period of rapid cooling and uplift occurred from 59 to 45 Ma, when the bounding faults of the adjacent Valhalla gneiss dome, the Valkyr shear zone, and the Slocan Lake fault zone were active. The rapid uplift is interpreted as being related to Eocene extension and the rise of the adjacent Valhalla gneiss dome during Eocene time.

Boundary Reaction

The Ni4Mo alloy has a short-range ordered fee structure (α) above 868°C, but transforms below this temperature to an ordered bet structure (β) by rearrangement of atoms on the fee lattice. The disordered α, retained by rapid cooling, can be ordered by appropriate aging below 868°C. Initially, very fine β domains in six different but crystallographically related variants form and grow in size on further aging. However, in the temperature range 600-775°C, a coarsening reaction begins at the former α grain boundaries and the alloy also coarsens by this mechanism. The purpose of this paper is to report on TEM observations showing the characteristics of this grain boundary reaction.
