What are primary particles and how are they different from primary minerals?
Fragment of a discussion from Course talk:APBI200
Primary particles are sand, silt and clay
Primary minerals are those minerals that have a very stable crystalline structure which does not weather easily and in which there are very limited isomorphic substitutions and consequently very limited number of charges. Examples of primary minerals are quartz, feldspars, olivine (see lecture from Jan 17, slide #9)
