they form in a large variety of physical and chemical conditions. the environment in which the mineral is formed determined it's properties. they can form both deep in the Earth's crust and on or near the Earth's surface.
Mineral deposits left behind that fill in the open spaces created by weaknesses in rock formation are called veins. Veins are formed through the process of hydrothermal fluids carrying minerals that solidify within cracks and voids in the host rock. This creates concentrations of minerals that can be economically significant for mining purposes.
Rocks are formed from the chemical compounds known as minerals - metal-silicates, carbonates, sulphates etc. You will also find secondary emplacement of minerals in fractures or other cavities in existing rocks, creating geodes, veins (including ore-bodies) etc.
Peacock ore, also known as bornite, is a sulfide mineral composed of copper, iron, and sulfur. It is not an igneous rock; instead, it is typically formed through hydrothermal processes in copper ore deposits.
Cuprite is an ore of copper. It is a secondary mineral formed by the oxidation of copper sulfide minerals, and is commonly found in the oxidized zones of copper deposits.
A long narrow deposit of a mineral in rock is typically referred to as a vein. Veins are formed when minerals are transported by fluids and deposited in cracks or fissures within existing rock formations. These deposits can be valuable sources of various minerals and metals.
Ore deposits such as gold are sometimes found as veins in rock formations. These veins are formed when mineral-rich fluids flow through cracks in the rock and deposit their minerals as they cool. Mining companies often target these veins as they are a concentrated source of valuable minerals.
A shaft mine is used to mine ore diposites from veins.
Underground mining is typically used when ore deposits occur in veins. This method involves underground tunnels and shafts to access the ore deposits. Miners can follow the vein and extract the valuable minerals for processing.
Ore bodies.
Gold ore is formed through a process called hydrothermal deposition, where hot fluids carry gold and deposit it in cracks and fissures in rocks. It can be found in nature in various types of rocks, such as quartz veins, in riverbeds, and in sedimentary deposits. Gold ore is typically mined from underground or open-pit mines.
The main ore of mercury is cinnabar, also known as mercury sulfide (HgS). Other minor ores containing mercury include livingstonite and metacinnabar. These ores are typically found in hydrothermal veins or volcanic deposits.

Quartz veins play a crucial role in the formation of mineral deposits because they act as pathways for mineral-rich fluids to flow through the Earth's crust. As these fluids move through the quartz veins, they deposit minerals such as gold, silver, and copper, creating valuable ore deposits. This process, known as hydrothermal mineralization, is essential for the concentration and accumulation of economically important minerals.
Gold ore is formed through a process called hydrothermal deposition, where hot fluids carrying dissolved gold and other minerals move through cracks in the Earth's crust. As these fluids cool and react with the surrounding rocks, the gold is deposited and accumulates in veins or deposits. This process can take millions of years to create economically viable gold ore deposits.
Minnesota is known to have the largest iron ore deposits in the United States, particularly in the Mesabi Iron Range. The state's iron ore is mainly used in steel production.
