Sedimentsare loose grains and chemical residues of earth materials which include things such as rock fragments mineral grains part of plants or animals and rust oxidized iron All sediments have. CLAYS. But why clay-. It is important to know where we are coming from , since the course of study in MNA/IMACS centers on clay and clay minerals basically. How are . clays . formed. Clays are formed from weathering of silica rich rocks . Sedimentary rocks cover ~ 75% of Earth’s surface. ~ 5 % (by volume) of Earth’s outer 10 miles. Contain evidence of past environments:.
