Ore in the Kamoa-Kakula deposits (Democratic Republic of Congo) is dominated by fine-grained Cu sulfides disseminated in Cryogenian diamictite matrix and siltstone, commonly with coarsely crystalline sulfide-gangue ‘caps’ and ‘beards’ on larger clasts. In addition to sedimentary material, ore-zone matrix contains hypogene Cu-sulfides, and ore-stage haematite and sericite. The finest-grained part of ore-zone matrix consists of randomly distributed, randomly oriented, irregularly interlocking subequant matrix crystals, with equant sulfide phases in interstitial pores. Millimetric subvertical swaths of microfoliated ore-zone matrix adjacent to larger diamictite clasts are dominated by sericite and are characterised by elongation and depletion of tectosilicates, dolomite, and Cu-sulfides. Removal of material from sides of silt-sized detrital particles in foliated ore-zone matrix was accompanied by syntaxial precipitation at their tops and bottoms, indicating that during horizontal compression, fluid-mediated pressure-solution and reprecipitation produced grain elongation and alignment, mass transfer (~−30%), and Cu-depletion in microfoliated matrix. This process explains the transfer of sulfide and gangue material into low-pressure areas on the tops and bottoms of the larger clasts (‘caps’ and ‘beards’). Ore characteristics were therefore produced by two distinct events: ‘early’ disseminated ore emplaced into isotropic diamictite matrix prior to orogenic compression and ‘late’ transfer of Cu and gangue minerals from diamictite matrix into clast-caps during Lufilian (late Neoproterozoic) compression.

Kamoa-Kakula 矿床（刚果民主共和国）中的矿石以细粒硫化铜为主，散布在成冰期杂岩基质和粉砂岩中，通常在较大的碎屑上有粗结晶的硫化物脉石“帽”和“胡须”。矿带基质除沉积物质外，还含有次成因硫化铜、成矿期赤铁矿和绢云母。矿带基质的细粒部分由随机分布、随机取向、不规则互锁的次等量基质晶体组成，间隙孔隙中有等量硫化物相。与较大的混积岩碎屑相邻的微叶理矿带基质的毫米垂直条带以绢云母为主，其特征是构造硅酸盐、白云石和硫化铜的伸长和耗竭。叶理矿带基质中粉砂大小的碎屑颗粒侧面的物质去除伴随着顶部和底部的结构沉淀，表明在水平压缩过程中，流体介导的压力溶解和再沉淀产生颗粒伸长和排列，传质(~−30%)，以及微叶化基质中的 Cu 耗尽。这个过程解释了硫化物和脉石物质转移到较大碎屑（“帽状物”和“胡须状物”）顶部和底部的低压区域的原因。因此，矿石特征是由两个不同的事件产生的：“早期”浸染矿石在造山压缩之前进入各向同性混积岩基质，以及在 Lufilian（新元古代晚期）压缩期间“晚期”铜和脉石矿物从混积岩基质转移到碎屑盖中。
