Copper, Silver, and Gold occur as elements instead of compounds.
Compounds built around the element carbon are called organic compounds. Carbon is unique in its ability to form long chains and complex structures, making it the basis for life on Earth. Examples of organic compounds include carbohydrates, proteins, lipids, and nucleic acids.
Nuclear Fusion
The products of a chemical reaction are the substances that are formed as a result of the reaction taking place. These products can be different compounds or elements from the reactants that were present before the reaction occurred.
Color change indicates a chemical reaction has occurred. The mixture of elements has different chemical properties than the original individual elements.
This process is known as planetary differentiation, and it is believed to have occurred early in Earth's history due to the planet's heat and pressure. The heavier elements sinking towards the core created the dense metallic core, while the lighter silicate minerals rose to form the Earth's crust and mantle. This differentiation is responsible for the layered structure of Earth.
When a chemical reaction occurs, elements and compounds combine in different ways to make new materials. The elements copper and oxygen have reacted to form a new compound, copper oxide.

Not in the truest sense, in that they have not occurred naturally.

Most minerals are created on geologic time scales of millions of years. The massive mining techniques and the huge consumption and demand for products created from minerals has only occurred in the last several centuries.
Minerals in metamorphic rocks can form due to changes in temperature and pressure, which cause existing minerals to recrystallize or new minerals to grow. The specific minerals formed depend on the original composition of the rock and the conditions under which the metamorphic process occurred.
For a crime to be said to have occurred, three elements must typically be present: an act or omission that is prohibited by law (actus reus), a culpable mental state (mens rea), and a concurrence of the act and mental state. These elements together form the basis of criminal liability.

Minerals that are commonly concentrated in heavily weathered sediments include clay minerals like kaolinite, iron oxides such as hematite and goethite, and aluminum-rich minerals like gibbsite. These minerals are resistant to weathering and can accumulate in areas where intense weathering has occurred, forming rich deposits.
