    The nature of the parent material strongly influences soil properties such as texture, pH, fertility, and mineralogy. For example, coarse-grained, quartz-rich parent material such as glacial outwash generates soils that are often gravely and with a coarse (sandy) texture. Soil parent material may be broadly grouped into the following classes:
