Clay-rich till

Just like regular till, clay-rich till is the result of the grinding and displacement of rock and soil by an inland ice sheet. This type of till is relatively rare and is found in areas of easily eroded sedimentary rocks such as limestone, shale and sandstone. Clay-rich till have a high proportion of clay particles (over 15 per cent) and is suitable for cultivation.
