摘要

克拉通边缘的新生代造山运动金矿化与地壳物质对岩石圈地幔的变质作用有关。板块俯冲将金从地壳转移到变质地幔,并使后者氧化,从而促进金在地幔熔体中的移动。由于缺乏地幔金源与上覆地壳金矿化相关的直接地球化学证据,挥发物在地幔金的移动过程中的作用尚不清楚。本研究利用大型灯泡岩中的锂同位素来描述华北克拉通东部地幔下的特征,该地区拥有巨大的中生代金矿床。我们的研究结果表明,地幔中的碳酸盐变质作用与上覆地壳中的金矿化之间有着密切的遗传联系。虽然地幔中金的预富集是形成巨型金矿床带的关键,但岩石圈地幔的氧化控制着金的移动。

The role of an oxidized lithospheric mantle in gold mobilization

The role of an oxidized lithospheric mantle in gold mobilization
Phanerozoic orogenic gold mineralization at craton margins is related to the metasomatism of the lithospheric mantle by crustal material. Slab subduction transfers Au from the crust to the metasomatized mantle and oxidizes the latter to facilitate the mobilization of Au into mantle melts. The role of volatiles in the mobilization of Au in the mantle is unclear because of the absence of direct geochemical evidence relating the mantle source of Au to Au mineralization in the overlying crust. This study uses lithium isotopes from a large suite of lamprophyres to characterize the mantle beneath the eastern North China Craton, which hosts giant Mesozoic gold deposits. Our results indicate a strong genetic link between carbonate metasomatism in the mantle and Au mineralization in the overlying crust. Although pre-enrichment of Au in the mantle is critical for forming giant Au provinces, the oxidation of the lithospheric mantle controls the mobilization of Au.
