Normal Fault

Red Siltsone:Pink red colored siltstone with alternating layer of silt and fine grained quartz, locay richin manganese and iron oxide.

Friable Sandstone:Pure sandstone, friable, locally with sandy-silt layers,locally contains varying amounts of manganese. manganese. These sandstones are interpreted as the product of decalcification of dolomitic sandstones.

Siliceous Sandstone:Sandstones eventually poorly selected microcrystalline silica, associated with ferruginous sandstones. Occur associated with ferruginous and manganesíferas breccias and might be associated with dolomitic rocks.

Sandy Siltstone:Sand siltstone, pink to red, sometimes laminated with sand levels, silt levels rich in manganese or iron oxides.

SLTg - Siltstone:Grey to black colors with minor to moderatecarbon content, containsalternating levels of silt and clay.(SLTcb - Carbon Up Grade Hydrothermal in Siltstone)

Diorite:Intrusive coarse-grained rock, green colored and reddish when altered. Composed mainly of feldspar, pyroxene and minor quartz.Weathers to clay.

Conglomerates:Matrix-supported conglomerates and locally clast-supported conglomerates intercalated . It has fragments of quartz and iron formation locally in sandy matrix with large concentrations of hematite.

Hematite Breccia:Rock with rhythmic banding of between silt and sand. The sand matrix is rich in Fe, and darkbrown Soil with many fragments smaller than 10 cm specularite

Gabbro:A green course grained basic igneous rock, consisting of plagioclase feldspar, clinopyroxene and orthopyroxene.

Schist: Chlorite talc schist, chlorite schist, with abundant biotite. with strong metamorphic foliation and tight micro folds.

Quartzite:Metamorphic rock composed mainly of microcrystaline quartz grains and locally contains an iron stained matrix.

Sedimentary Breccia:A rock composed of broken fragments of minerals or rock cemented together by a fine-grained matrix, that can be either similar to or different from the composition of the fragments
