文章专门讨论与特定成岩作用伴生的铬、铂和硫化物矿床形成的内生因素。该类成岩作用对矿石富集有显著影响。矿床的巨大规模起因于与广泛强烈的成岩过程有关的特殊的成矿作用。这些作用导致产在超基性杂岩中的特殊纯橄榄岩（铬矿石）、基性超基性层状侵入体中的低硫层和铁镁橄榄石纯橄榄岩（铂族金属矿床）的形成，以及富铁火成分异岩的透岩浆硫化作用（ＣｕＮｉ硫化物和ＣｕＺｎＰｂ硫化物矿石）。还根据巨型矿床的成因模型提出了矿物学岩石学的找矿标志
The article is devoted to the endogenous factors that form with chromium, platinum and sulfide deposits associated with a particular diagenesis. This type of diagenesis has a significant effect on ore enrichment. The enormous size of the deposit results from the special mineralization associated with the extensive and intense diagenetic processes. These effects result in the formation of special dunites (chromite) produced in ultramafic complexes, low-sulfur layers in basaltic ultrabasic lavas and intrusions of iron-forsterite dunites (platinum group metallogenic deposits) Formation and transgrown sulfide (Cu-Ni sulfide and Cu-Zn-Pb sulfide ores) of different types of iron-rich fires. According to the genesis model of giant deposits, mineralogical petrology prospecting indicators are also proposed
