The older alluvium composed of lime nodules is called "kankar." Kankar is a type of calcareous nodular material that forms in the soil, typically in arid and semi-arid regions, and is commonly found in older alluvial deposits. These lime nodules develop due to the precipitation of calcium carbonate from groundwater, which accumulates around soil particles, forming hard, cemented layers or nodules.
