See Factors controlling dike injection and STOP 6 for discussion of this model. Roadmap of eastern California with locations of planned stops. Topographic map of Poison Canyon, southern Argus range, and location of STOP 3. The mafic dike to the west was drilled extensively for anisotropic magnetic susceptibility. Suggested traverse is shown by dashed line with arrows.
Dikes are extremely abundant in the metamorphic rocks.
The mafic dike is, in turn, deformed along a mylonite zone immediately to the east. Equal-area stereonet plot of poles to mylonitic foliations measured in the Woods Lake area, eastern Sierra. The mylonite zones dominantly strike north-south and dip moderately eastward. A mafic dike in Woods Lake area, eastern Sierra, may have filled conjugate fractures. Compare with Fig.
