Types of Metamorphism. Regional metamorphism Large scale – large volume of rock is affected Associated with convergent plate margins and mountain building Folding and faulting increase thickness of the crust Occurs over a range of temperatures and pressures Fluids are also presentBy juro
Lab 3 – Structural Geology and Earthquakes. Definitions. Structural Geology – study of how geologic units (bodies of rock or sediment) are arranged when first formed and how they are deformed afterward. Geologic Map. Geologic map – shows the distribution of rocks at the Earth’s surface.By beth

Sediment and Sedimentary Rock. The two primary types of sediment are detrital and chemical. Sedimentary rock is simply rock made up of consolidated sediments.. Detrital sediment consists of solid particles, products of mechanical weathering. Chemical sediments consist of minerals precipitated from
Scroll down to see animation. Deposition of Sediment… Sedimentary Rock Layers. By Principle of Superposition, Oldest is on bottom… youngest on top. Tilting by tectonic activity. Tilting must be after deposition by Principle of Original Horizontality.
Chapter 8 – FROM SEDIMENT INTO SEDIMENTARY ROCK. Sediments and Sedimentation. Deposition Laying down of sediment Separated into 3 broad categories Clastic ( Detrital ) Chemical Biogenic (Biochemical). Clastic sediment Fragmented rock & mineral debris from weathering & erosion
Sedimentary Rock. Sedimentary Rock. Sedimentary rock is created when existing rock breaks down into sediments , and then the sediments are recombined by compaction and cementation. Sedimentary Rock. Sediments are created by three forces: Weathering Erosion Deposition. Weathering.
Sedimentary Rock. Section 3.3. Sedimentary Rocks. All sedimentary rocks begin to form when existing rocks are broken down into sediments through a process called weathering Weathering is the process in which rocks are physically and chemically broken down by water, air, ice and gravity
Sedimentary Rock. Organizing Sedimentary Rocks. All made through the compacting and cementing of layers of… Sediment – any fragment or piece of rock, plant, animal, or dissolved mineral. Three Types of SR: sorted by the material that forms them . 1. Clastic. 2. Chemical. 3. Organic.
Sedimentary Rock. Chapter 10.3. Sedimentary Rock. Sedimentary Rocks Sedimentary rocks are formed when sediment deposits harden after being compressed and cemented together. Two process that form sedimentary rock are compaction and cementation. Sedimentary Rock.
Sedimentary Rock. Chapter 4 Section 3. Sedimentary Rock. Forms when wind or water deposit sediment Sediment – small pieces of material that come from rock or living material. Processes. Erosion – running water, wind or ice carry away fragments of weathered rock
