PPT-UNIT - 4 Sedimentary Structures

TRANSPORT MEDIA Gravity is the simplest mechanism of sediment transport It includes the movement of particles under gravity down a slope Rock falls generate piles of sediment at . Biogenic and Chemical Sedimentary Rocks. . Chemical Sedimentary Rocks. In contrast to detrital rocks, which form from the solid products of weathering, . chemical sediments . derive from ions that are carried in solution to lakes and seas. . (pages 102–106). 1. Describe how sedimentary rocks form.. 2. List and describe the three major types of sedimentary rocks.. Objectives. write these down!. Sediment. Erosion. Deposition. C. ompaction. OR. Strategy:. Relate sedimentary characteristics of ancient deposits (grain size, . sedimentary . structures, geometry) to features observed in modern rivers. Bedforms. during traction deposition from unidirectional flow. Geology 103. Depositional environment. Is the term given to the area where the sediment was originally deposited. Must be inferred from the rock identity. Clastic. . depositional environments. Dominated by actions of waves, tides and currents. UNIT . 5. What are Sediments. Sediments are loose Earth materials (unconsolidated materials) such as sand . which are . transported by the action of water, wind, glacial ice and . gravity.. These . materials are . What is the difference between clastic and non-clastic sedimentary rocks? . What we know. The process of formation for a sedimentary rock involves the following steps:. Weathering. Erosion. Deposition. What You Will Learn. Describe the origin of sedimentary rock. . Describe the three main categories of sedimentary rock. . Describe three types of sedimentary structures. . Where does Sand come from?. What are Sediments. Sediments are loose Earth materials (unconsolidated materials) such as sand . which are . transported by the action of water, wind, glacial ice and . gravity.. These . materials are . . Chemical Sedimentary Rocks. In contrast to detrital rocks, which form from the solid products of weathering, . chemical sediments . derive from ions that are carried in solution to lakes and seas. . Normally we think of time in terms of days or years but geologists commonly refer to events that happened millions or billions of years ago. For example earth is approximately 4.6 billion years old. GEOLOGIC TIME. Kinematic analysis of deformation. B. Natalin. Structural geology and tectonics. Structural geology is the study of deformation of rocks. - we study such features as folds, faults, their geometry, movements, origins;. A rock is a natural substance that is made up of solid crystals of different minerals that have been fused together into a solid lump. . Rocks can be classified by their attributes: . Texture. Hardness. Sedimentology. and . Stratigraphy. What are Sediments. Sediments are loose Earth materials (unconsolidated materials) such as sand . which are . transported by the action of water, wind, glacial ice and .
