However, when occurring in Mesozoic remelted granite, pyrite is featured mainly by high gold content in pentagonal dodecahedron and in its complex; low content in cubic pyrite; Au/Ag ratio between 1-2; both N and P types of pyrite present in most deposits and P type only in a few deposits.

The results show that the fine-grained hypidiomorphic pyrite, with a crystal form of pentagonal dodecahedron, contains more Au than others. Since the areas yield pyrite with relatively lower contents of main components S and Fe, while a greater gross content of trace elements, such as Cu, Pb, Zn, Au, Ag, are closely associated with gold deposits, the authors propose that a middle-scale gold deposit might be found in Zhaojiapuzi area; and there is a remote possibility to find a large gold deposit in Shengjingao area, wih a prospect of finding a concomitant gold deposit.gold deposits;mineralogical.
