中温热液金矿床及其“特殊源岩”对太古代中温热液金矿床的成因,目前流行两种不同的成因模式,但二者都存在不足之处。(1)岩浆模式(Burrows et al,1986)认为,成矿流体和金均来自与金矿床有关的花岗岩/斑岩侵入体;然而,由于已作过分析的侵入岩体的金含量过低(Mayer 和 Saager,1985),无法解释那些巨大规模的金矿床。(2)变质模式(Groves 和 Phillips,1987)
The genesis of mid-temperature hydrothermal gold deposit and its “special source rock” in the Archean mid-temperature hydrothermal gold deposit are two popular generative modes, but both of them have some shortcomings. (1) The magmatic model (Burrows et al., 1986) argues that both the ore-forming fluid and the gold come from granite / porphyry intrusions associated with gold deposits; however, since the gold content of the intrusive rock that has been analyzed is too low Mayer and Saager, 1985) can not explain the huge gold deposits. (2) metamorphic patterns (Groves and Phillips, 1987)
