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.

产于中生代重熔花岗岩中时，黄铁矿以五角十二面体居多，五角十二面体及其聚形含金较高，立方体含金性较差；Au/Ag比值在1-2之间，As的含量较高(＞600×10〓)；Co、Ni的含量则较低，一般为10n×10〓；热电性以既有P型又有N型的P、N混合型为特征，少数金矿床表现为单一的P型。
