The result of X-ray diffraction test of the gypsum rock sample is shown in Table 1, and the X-ray diffraction pattern is shown in Figure 4.These are called solution sinkholes. These rocks dissolve when attacked by rainfall or groundwater that is acidic. Solution sinkholes have sides that vary from gentle slopes to almost vertical, while their shapes include saucer-like hollows, cones, cylindrical potholes and shafts. Streams or rivers may enter a sinkhole and disappear underground.
