Figure 3 shows Ficus prolixa, or nunu, a tall common native tree species adapted to the shallow limestone soil.While limestone itself doesn’t affect the environment, limestone mining can have a negative impact. On the other hand, the environment can affect limestone by breaking it down. Limestone mining can pollute water and create sinkholes.The lichens may possess acidic properties which dissolves the limestone and indirectly enhances chemical and physical weathering. Large tree roots growing in the area can also exert pressure on limestone. The combination of all 3 weathering processes subsequently disintegrates the limestone, and soil genesis begins. Limestone is a carbonate sedimentary rock that consists predominantly of calcite [CaCO 3].Limestones are the commonest rocks that contain non-silicate minerals as primary components and, even if they represent only a fraction of all sedimentary rocks (about 20 – 25%), their study is fundamental to understand past environments, climate, and the evolution of life.The Kaibab Limestone is a resistant cliff-forming, Permian geologic formation that crops out across the U.S. states of northern Arizona, southern Utah, east central Nevada and southeast California.
