As a result of the removal of Mg and Si from the ultramafics, chromite has been enriched in the lateritic soils by a factor ranging from 2 to more than 10. In some areas, soils of different ultramafic rocks are mixed due to alluvial processes which can cause further enrichments of chromite. These mixed soils often occur as transported soils

In order to determine if cells are low grade, pathologists often compare the abnormal-looking cells to the cells normally found in that part of the body. The term low grade can be used to describe cells found in both precancerous conditions and cancers. The term low grade is also found in the names of many different types of tumours.
