LAB 3: COMMON MINERALS IN SEDIMENTARY ROCKS, Part 1

Quartz is a common rockforming mineral, and resistant to both chemical and physical weathering. Accordingly, it is a common constituent of clastic sedimentary rocks. Feldspars are relatively stable in the surface environment, with potassium feldspars being more resistant to chemical weathering than plagioclase. Mafic minerals readily weather to form clays and iron hydroxyoxides, and so are ...
