Generally, it is considered that P type of pyrite is usually formed in sulphur- rich hydrothermal fluids.

3一般认为，成矿溶液中富S有利于形成P型黄铁矿。

However, because S is more easily combined with Fe than As does, hence when hydrothermal fluids are rich in S, the possibility of As presence in pyrite crystal lattice decreased, but the chance for Co and Ni to substitute Fe in pyrite crystal lattice increased, thus S rich is not favorable for the formation of P type of pyrite.

但另一方面，由于S与As相比更易与Fe结合，因而成矿介质中富S将使As进入黄铁矿晶格中的能力或几率降低，并进一步使Co、Ni因补偿类质同像进入黄铁矿晶格中代替Fe的能力或几率增大，反而不利于形成P型黄铁矿。
