Mar 17, 2017· The oxide minerals are compounds of metallic elements plus oxygen, with two prominent exceptions: ice and quartz. Ice (H 2 O) always gets left out of the mineral books. Quartz (SiO 2) is treated as one of the silicate minerals.Some of them are primary minerals that solidify deep in the Earth in magmas, but the most common oxide minerals form near the surface where oxygen in the air and …

Oxide mineral | Britannica

Some examples of minerals in iron-rich rocks containing oxides are limonite, hematite, and magnetite. An example of a mineral in iron-rich rock containing carbonates is siderite and an example of minerals in an iron-rich rock containing silicate is chamosite. They are often interbedded with limestones, shales, and fine-grained sandstones.

Mineral - Classification of minerals | Britannica

Sulfides are minerals that contain sulfur. These minerals are inorganic compounds, which means that they are formed through geological rather than biological processes. These minerals are commonly found in soils with a higher temperature. Oxides are those minerals that contain oxide anions, or oxygen, with ice and quartz being the exceptions.

Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, in veins, and in alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).
