Cawood et al. (this issue) critize our hypothesis of a pre-Klondikean weathering/oxidation event having affected the Aggeneys-Gamsberg ore district. Instead, they reinforce the long-held view that the sulfide deposits of the ore district with its pronounced metal zonation, its unusually high mineralogical variability and numerous geochemical anomalies are the product of amphibolite- to granulite-facies metamorphic overprint of originally syn-sedimentary exhalative deposits. Here we gladly use the opportunity to counter all issues raised and explain further our evidence of oxidation and subsequent re-sulfidation of the original synsedimentary deposits.

回应：Stefan Höhn、Hartwig E. Frimmel 和 Westley Price 对“南非 Gamsberg 锌矿床的同步变质硫化作用”的讨论

卡伍德等人。（本期）批评我们关于影响 Aggeneys-Gamsberg 矿区的克朗代克纪前风化/氧化事件的假设。相反，它们强化了长期以来的观点，即矿区的硫化物矿床具有明显的金属分带、异常高的矿物学变异性和众多地球化学异常是角闪岩相至麻粒岩相变质叠印的产物。存款。在这里，我们很高兴利用这个机会反驳所有提出的问题，并进一步解释我们关于原始同沉积矿床氧化和随后再硫化的证据。
