The examination, with a scanning electron microscope, of 200 quartz grains from a tropical environment (Uganda) shows the nature of chemical weathering on these grains. Five main types of features occur: solution pits; solution crevasses; chemical etching along quartz structures; blocky forms probably resulting from swelling; and widespread disintegration of the grain surface. Few of these features have previously been recorded.
