QIN Dong Institute of our team (1964-1966, 1973) successively in the area had 1/10000 route geological observation, made from Wu Guan to bluegrass and Jiaojiazhuang, mule Ping, Shihmen, gray pond, business South, drift pool, python and other granite granite body 1/1000 geological profiles, and the system collected a variety of samples. In recent years, we studied pegmatite in this area
