This area extends about 50 miles southeast of the Blue Eidge and northwestward nearly to the Tennessee line. (See fig. ) Mica mining has been carried on in eighteen or more of the counties includedAuthor: D.B.
Sterrett, Sydney Hobart Ball. The pegmatites in the Pala district occur in a curving belt that occupies an area of about 13 square miles. The belt extends from Pala Canyon south-southeastward to the southern base of Pala Mountain, and within it are exposed at least pegmatite dikes.
Other pegmatites are scattered through the surrounding area. Chrysoberyl is also of interest; Brown says that “transparent yellow stones of good quality occur with beryl in mica-bearing pegmatites at Govindsagar, Kisangarh, Rajasthan.” (). Another association is with aquamarine (a gem variety of beryl); “some beautiful aquamarines have come from the mica mines, 1 1/2 miles west of Saidapuram.

In the first stage the following zones appear to have formed by successive deposition from the walls inward: border zone, muscovite-quartz zone, perthite zone, and quartz core. exposed in the Brazil Lake pegmatite. These lobes are referred to informally as the northern and southern pegmatites, with reference to their location to the Holly Road (Fig.
