· Key Differences. Primary minerals crystallize directly from molten magma, capturing the original chemical composition of the rock. Secondary minerals form from the alteration of primary minerals, usually through processes like weathering and hydrothermal activity. 6. In terms of stability, primary minerals are stable at high

· Geology. The key difference between primary and secondary minerals is that primary minerals are formed from primary igneous rocks whereas secondary minerals are formed from weathering of primary rocks. A mineral is a naturally occurring, inorganic solid substance that has a well-ordered chemical structure.

· Propylitic alteration is a type of hydrothermal alteration that occurs in volcanic and plutonic rocks. It is characterized by the alteration of primary minerals, such as feldspar and quartz, to secondary minerals, such as chlorite, epidote, and sericite. Propylitic alteration typically occurs at lower temperatures (less than 200°C) and

Hypogene. In ore deposit geology, hypogene processes occur deep below the Earth's surface, and tend to form deposits of primary minerals, as opposed to supergene processes that occur at or near the surface, and tend to form secondary minerals.
