Eight foot exposure of interbanded amphibolite, pyroxenite, and granite pegmatite. Contains black vitreous knobs of Allanite composing approximately 10 percent of the exposure.

"In a field 700 feet north of the barn on the farm of Mr. Welsh, lot 8, con
cession X, Monteagle township, there is a small 8-foot exposure of interbanded
amphibolite, pyroxenite, and granite pegmatite. The rock is distinctly gneissic and contains numerous knobs of black vitreous allanite up to 4 inches in diameter. The allanite makes up about 10 percent of the exposure."
