摘要：

Root distribution was studied in a soil having a paralithic contact in southeastern Montana. An abrupt change in root abundance was the most useful criterion for locating the paralithic conact. The soft rock is indistinguishable from the overlying soil in texture, color, structure and water-holding capacity, but has a bulk density of 1-50 g/cm3 and is hard, whereas the soil has a bulk density of only 1.35 g/cm3 and is soft when dry.-from Authors
