The types of secondary minerals formed from the weathering and hydrolysis of common primary minerals are given below. The mineral names are not important here, except to note that

Soil Mineralogy - Encyclopedia of Life Support Systems

Secondary minerals are re-crystallized or transformed products of the chemical breakdown and/or alteration of primary minerals under ambient conditions. Secondary minerals are mainly found in the clay and fine-silt fractions because the particle size of primary minerals usually decreases during weathering. Typical secondary minerals

CLAY MINERALS - Southern Research

primary minerals (quartz, micas, and some feldspars) may persist in soils, other less resistant minerals (pyroxenes, amphiboles, and a host of accessory minerals) are prone to breakdown and weathering, thus forming secondary minerals. The resultant secondary minerals are the culmination of either alteration of the primary mineral

Primary and secondary deposits of diamonds - Diamant-Gems

Diamond deposits can be divided into two categories : primary and secondary deposits. Primary deposits are volcanic craters that have caved in on themselves and contain vertical kimberlite "pipes" that shrink until they crack (1). These can also occur as long, narrow veins, both vertical and oblique that spread over several kilometres.
