The Kamoa North Bonanza Zone represents a new style of copper mineralization at the Kamoa-Kakula Project in the Democratic Republic of Congo (DRC), where massive to semi-massive chalcopyrite, bornite and chalcocite have locally replaced pyrite in the Kamoa Pyritic Siltstone (KPS) - a pyritic siltstone that lies immediately above the basal diamictite unit that typically hosts the copper mineralization at Kamoa-Kakula.

The conglomerates are Diamictite, mostly clasts are derived from igneous origin.
The Boorthanna Formation, which forms the deeper aquifer (called lower aquifer in this work), is a marine and glacial sandstone and diamictite aquifer that overlies Proterozoic basement rock [55] (Figure 1(c)).
In the younger rocks, they discovered diamictite, a clay-rich sedimentary rock typically formed in glacial environments.
This outcrop, in the Rio Bonito Formation, of Permian age, was chosen by its distinct sedimentary rocks succession as diamictite, carbonaceous pelite, and sandstone, respectively, from bottom to top.
First, the Snowball model is based on stratigraphic analyses, which, to borrow Harland and Herod's (1975) phrase are 'sedimentologically unsophisticated" Old, and by now very shop-worn assumptions that poorly sorted diamictite facies must be continental tillites deposited below ice sheets, and any fine-grained, rhythmically laminated facies are glaciolacustrine varvites, can still be found in the Snowball literature (Hoffman et al., 1998; p.
Melanic soils develop from a variety of parent materials (Van der Merwe 2000), including arkosic sandstone, siltstone, mudstone, shale, diamictite, dolerite, basalt, notite, amphibolite, granite, gneiss, rhyodacite, and carbonates.

It consists of Diamictite glacial deposits (TBI), wash out plain deposits (TB2) and followed by subaqueous Diamictite facies (TB3).
