gilgai — A microfeature pattern of soils composed of a succession of microbasins and microknolls on level areas, or of microtroughs and microridges parallel to the slope on sloping areas, and produced by expansion / contraction and shear / thrust… … Glossary of landform and geologic terms
elliptical gilgai — A type of gilgai dominated by elliptical, closed and semi closed depressions (microlows) separated by low mounds or ridges (microhighs); the prevailing type of gilgai on mildly sloping terrain (slopes 3 – 8 %); as slope increases, basins… … Glossary of landform and geologic terms
linear gilgai — A type of gilgai dominated by parallel troughs (microlows) separated by low ridges (microhighs) and oriented perpendicular to the topographic contour (i.e., up and down slopes); the prevailing type of gilgai on sloping terrain (slopes > 8… … Glossary of landform and geologic terms
