Hadamengou 金沉积物位于北方中国 craton 的北边缘的西方的部分。它是与碱的 magmatism 有关的热水的沉积物。Au 的溶解，从黄铁矿和氧化铁(包括的磁铁矿和赤铁矿) 的 Fe 在矿石表演的三种主要类型的单个矿物质：在氧化铁(磁铁矿和赤铁矿) ， Au 和 Fe 同时被溶解，他们的溶解度断然被相关，它意味着 Au 主要是结合化学药品的(格子金牌) 或在氧化铁的胶体吸附；当相反，在黄铁矿 Au 溶解显然落后于时， Fe 和 Au 的溶解度与 Fe 的显示出否定关系，它显示 Au 主要作为元素的黄金的谷物被招待(或本国的黄金) 在内黄铁矿。以前的研究表明 Hadamengou 金沉积物被氧化铁的高内容偶尔由硫化物代替了的集中的 K-feldspathization 和抓住描绘，它被氧化在一个拉长的 geodynamic 背景下面引起充实 K 的碱的液体。这些地质的特征和在氧化铁的高 Au 内容，与在南方澳大利亚的奥林匹克水坝沉积物的可比较，建议这沉积物是在中国的铁氧化物类型金牌沉积物的第一个例子。

Dissolution of Au, Fe frompyrite and iron oxide (including magnetite and hematite) individual minerals in the three main types ofore shows: in iron oxides (magnetite and hematite), Au and Fe were dissolved simultaneously and theirsolubilities are positively correlated, which means Au is mainly chemical-bonded (lattice gold) and/orcolloidal-adsorbed in iron oxides; while in pyrite, on the contrary, Au dissolution obviously lags behindFe and the solubility of Au shows negative relationship with that of Fe, which indicates Au is mainlyhosted as grains of elemental gold (or native gold) within pyrite. Previous studies revealed that theHadamengou gold deposit is characterized by intensive K-feldspathization and holds high content ofiron oxides occasionally replaced by sulfides, which was caused by oxidizing K-enriched alkaline fluidsunder a stretching geodynamic setting. These geological features, together with the high Au-content iniron oxides, comparable with that of the Olympic Dam deposit in South Australia, suggest that thisdeposit is the first example of iron oxide-type gold deposits in China.
