A mineral is a naturally occurring crystalline solid that cannot be physically broken down into smaller components.. Deposits of minerals form when a medium that contains and transports mineral-making ore releases and deposits the ore. Magma is one such medium that transports ores. When magma or lava cools, the magma and ore …

The minerals are mixed evenly throughout the water to make a solution. The mineral particles in water are so small that they will not come out when you filter the water. But, there are ways to get the minerals in water to form solid mineral deposits. Minerals are smaller than sand particles and germs.

The minerals in the original rock were formed at one set of conditions, but were then subjected to different conditions of heat, pressure, and H 2 O abundance in Earth's crust. They responded to that change by transforming to become minerals stable under the new conditions. Metamorphic rocks and minerals record the history of the dynamic Earth.

Another type of chemical bonding can occur between elements in the formation of minerals that involves electron sharing. This is most easily explained in looking at a simple molecular model of (ce{H2O}), water. Oxygen has 6 electrons in its valence shell and hydrogen has only one. By sharing these electrons, the valence shells …

This allows more unusual minerals to form, including gem minerals. Simple pegmatites are just overgrown minerals of the same type as those in the parent granite rock, such as feldspar, mica and quartz. Exotic pegmatites can carry minerals with rare earth elements, or zirconium, caesium, beryllium, boron, lithium and fluorine.

Formation of Clay Minerals. As already noted, clay minerals typically form from the alteration (hydrolysis) of pre-existing silicate minerals. The type of clay mineral that will form in any situation depends partly on what silicate mineral is being altered, but also on a range of other variables such as the temperature and pressure, and the …
