SUMMARY In soils in south-western Australia rounded quartz pebbles and sand grains have been greatly modified by chemical dissolution. Evidence of dissolution was provided by thin sections, scanning electron microscopy and measurements of quartz grain strength. Dissolution is initiated at fractures and intercrystalline boundaries so that dissolution along intersecting microfractures produces various surface etch features including tessellated pyramidal surface textures. The alteration of… CONTINUE READING
