GEOL 1425 1st Edition Lecture 7Outline of Last Lecture I. Igneous rocksII. MagmaIII. Different types of igneous rocksOutline of Current Lecture I. Sedimentary RocksII. Processes that form sedimentary rocksCurrent Lecture- Surface process provide framework for sedimentary rock.- Sediment in deposited into basins - The interaction of the geosphere, hydrosphere, and atmosphere produce sediment. This breaks it into particles which are carried by wind, water, or glaciers- Water sinks into the soil and reacts with rocks, clay is usually produced. - Water reacts with ions to change the composition of rocks.- Feldspar reacts with water- Quartz does not react with water - When water freezes and cracks structure is physical weathering- Glaciers can carry huge amount of material, from boulders to silt. - Glaciers will literally shine the surface of rocks as they slide over them- Depending on the size of a given particle determines what might be transporting it. Wind carries small particles while water is capable of moving boulders. Ice can move huge boulders.- Sediment basins produce petroleum. There are oil rigs associated with geological basins. - Flexural basins associated with converging boundaries. - Rift basins are associated with diverging boundaries. - Lithification: turning sediment into rock by compaction or cementationThese notes represent a detailed interpretation of the professor’s lecture.
