Donald W. Hyndman, Professor
Ph.D. University of California, Berkeley, 1964

Specialization:

Igneous Petrology, Geologic Hazards.

Particular interests:

Granitic batholiths including Idaho batholith.

Geological hazards and disasters.

Tectonic/structural environments for granitic batholiths.

High-potassium alkalic rocks, including Central Montana High-Potassium Province.

Basin-scale basaltic sills, including giant Proterozoic sills of the Belt basin.

Magma differentiation and mixing.

Major mylonite zones in high-grade rocks.

My approach to petrology involves major use of field, petrographic, and chemical data, in conjunction with tectonic environment/regional geology. It emphasizes integration of as many different kinds of data as are available to develop and test viable models for the study involved. My students work on any reasonable petrologic project with which I feel comfortable.
