PPT-UNIT – 2 Detrital Sedimentary Rocks

Clastic Sediments and Sedimentary Rocks Clastic sediments are loose materials however when these sediments under go lithification diagenesis they form sedimentary rocks Clastic sedimentary rocks are also known as . 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. What is a sedimentary rock?. Sedimentary rocks are products of mechanical and chemical weathering. They account for about 5% (by volume) of Earth’s outer 10 miles. Contain evidence of past environments. . r. ocks. 97,3% of Hungary is . covered. . with. . some. . kind. . of . sediment. 75% of land surface on the earth is covered by thin veneer of sediments or sedimentary rocks.. Classification. . 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 . applied to sedimentary basins. Barbara . Carrapa. After Painter et al. (2014). Thermochronology applied to sedimentary . basins. Timing and patterns of erosion, which informs about processes of basin formation.. Sedimentary-sandstone. Metamorphic- gneiss. Igneous- diorite. 1. What is a Rock?. Naturally Occurring . (not man made). Solid. Mixture of minerals other organic matter. 2. What makes a rock different from a mineral?. 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. a. metamorphic rock. . b. sedimentary rock. . c. igneous rock. d. sediment. . #1. Which of the following processes is NOT part of the rock cycle?. a. solidification. . b. chiseling. c. erosion. d. metamorphism. Sedimentary rocks form in 1 of 3 ways:. 1. . Clastic. Sedimentary Rocks- made of pieces and grains of other rocks. Material such as . sand . or . mud. -usually deposited in . water. Conglomerate sandstone. Favs. .. . Where do sediments come from?. - Weathering. – breaking down rock into smaller pieces chemically and physically.. - Erosion. - carrying away the particles and depositing them. . Glaciers.

Do Now. 1.  What is an igneous rock?. 2. How do sedimentary rocks form?. Sedimentary Rocks -. are one of the three main rock types . A sedimentary rock can form one of three ways: . by the . deposition. Mahyra Tedeschi. 1*. , . Humberto Reis. 2. , Laura Stutenbecker. 3. , Matheus Kuchenbecker. 4. , Bruno Ribeiro. 5. ,. .
