Uranium deposits of this type occur in and near volcanic calderas, in acid to intermediate volcanic rocks, and are related to faults and shear zones. Uranium occurs in veins or is disseminated and is commonly associated with molybdenum and fluorite.
The zoning found in ore deposits is dominantly of two distinctive types: that in syngenetic sedimentary deposits, like the Kupferschiefer, and that in common hydrothermal deposits of either epigenetic or syngenetic characteristics.

Iron ore mining methods vary by the type of ore being mined. There are four main types of iron ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits.

These deposits form as enormous quantities of hot brine migrate through the rock, opening cavities and depositing minerals, oil and gas. Low Temperature Minerals. Malachite is a green copper carbonate which forms when copper ore weathers, meaning it is changed by air, water, and other environmental factors. Malachite is often used as an ornamental mineral.
Uranium ore deposits are found globally, with the largest known recoverable resources found in Kazakhstan, Canada, Australia and South Africa. The metal is so abundant that it can be found almost everywhere in soil, rivers, oceans and rocks.
The iron ore deposits began forming when the first organisms capable of photosynthesis began releasing oxygen into the waters. This oxygen immediately combined with the abundant dissolved iron to produce hematite or magnetite.

Metallic Deposits Metals occur in all kinds of rocks but usually in concentrations that are too low to be mined. Metallic ore deposits, however, are relatively rare concentrations of metal‐bearing minerals (usually sulfides) that contain enough metal to be profitably mined.
Information about iron ore deposits in South Australia is available in M20 Iron ore deposits in South Australia (PDF ) The major use of iron minerals in South Australia has been for the production of pig iron for the manufacture of steel.

Ore deposits have formed at various periods over geological time from at least 3500 million years ago to the present day where mineral deposits are forming as part of .
Ore Geology Reviews aims to familiarize all earth scientists with recent advances in a number of interconnected disciplines related to the study of, and search for, ore deposits. The reviews range from brief to longer contributions, but the journal preferentially publishes manuscripts that fill the niche between the commonly shorter journal articles and the comprehensive book coverages, and thus has a special .

A common type of ore deposit is the one formed by actions of hot water, the hydrothermal type. For this type of deposit we may ask the following types of
