Surficial processes are the physical and chemical phenomena which cause concentration of ore material within the regolith, generally by removal of chemical constituents by aqueous leaching. This includes laterite deposits and residual or eluvial deposits.

continental sediments and volcanics
Mineral deposits associated with sediments or volcanic material on continental crust. They form where volcanic rocks and ash layers react with alkaline groundwater, and may also crystallize in post-depositional environments over periods ranging from thousands to millions of years in shallow marine basins.

sediment-hosted
Sediment-hosted deposits can be divided into two major subtypes. The first subtype is clastic-dominated lead-zinc ores, which are hosted in shale, sandstone, siltstone, or mixed clastic rocks, or occur as carbonate replacement, within a clastic-dominated sedimentary rock sequence. This subtype includes deposits that have been traditionally referred to as sedimentary exhalative (SEDEX) deposits. The second subtype of sediment-hosted Pb-Zn deposits is the Mississippi Valley-type that occurs in platform carbonate sequences, typically in passive-margin tectonic settings.

Epithermal deposits occur largely in volcano-plutonic arcs associated with subduction zones, with ages similar to those of volcanism. The deposits form at shallow depth, less than 1 km, in the temperature range of 50°-200°C, are hosted mainly by volcanic rocks, and occur mainly as veins.

manto
Manto ore deposits are defined by a strict stratigraphic control on their distribution, generally within a porous formation within a structural trap site. The source of ore within manto deposits is considered to be interformational, from a sedimentary source within an adjacent sedimentary basin, or from ore fluids driven off from intrusive rocks.

porphyry
Porphyry deposits are intrusion-related, large tonnage low grade mineral deposits with metal assemblages that may include all or some of copper, molybdenum, gold and silver. The genesis of these deposits is related to the emplacement of intermediate to felsic, hypabyssal, generally porphyritic intrusions that are commonly formed at convergent plate margins.

carbonatites
Carbonatites are intrusive carbonate-mineral-rich igneous rocks, many of which contain distinctive abundances of apatite, magnetite, barite, and fluorite, that may contain economic or anomalous concentrations of rare earth elements, phosphorus, niobium, uranium, thorium, copper, iron, titanium, barium, fluorine, zirconium, and other rare or incompatible elements. They may also be sources of mica or vermiculite. Carbonatites may form central plugs within zoned alkalic intrusive complexes, or as dikes, sills, breccias, and veins.

pegmatite
Pegmatites tend to occur in the aureoles of granites in most cases, and are usually granitic in character, often closely matching the compositions of nearby granites. Pegmatites should thus represent exsolved granitic material which crystallises in the country rocks. However, an origin of pegmatite fluids by devolatilisation (dewatering) of metamorphic rocks is also envisaged. Pegmatites are coarse-grained rocks, mainly composed of quartz, feldspar and mica and are important because they often contain rare earth minerals and gemstones, such as aquamarine, tourmaline, topaz, fluorite, apatite and corundum, often along with tin and tungsten minerals, among others.
