Secular Changes in Global Tectonic Processes and Their ...

Mineral deposit types commonly have a distinctive temporal distribution with peaks at specific periods of Earth history. Deposits of less redox-sensitive metals, such as gold, show long-term temporal patterns that relate to first-order changes in an evolving Earth, as a result of progressively declining heat production and attendant changes in global tectonic processes.

Mineral deposit | Britannica

All ore deposits are mineral deposits, but the reverse is not true. Ore deposit is an economic term, while mineral deposit is a geologic term. Whether a given mineral deposit is also an ore deposit depends on many factors other than the level of concentration and the size of the deposit; all factors that affect the mining, processing, and transporting of the ore must be considered as well.

Finally, preservation affects mineral deposits post-deposition and can result in erosion, upgrading and dispersion of in-situ mineralisation. For example, the formation of alluvial deposits represents the removal of mineralisation from an in-situ ore body, affecting the distribution of mineralisation within the assessment domain.
