K-feldspar enrichment in the Pacific pelagic sediments …

The mineralogy of atmospheric silicate dust controls its interaction with clouds. K-feldspar has a remarkably high ice-nucleating activity, and its distribution may have influenced the global climate throughout Earth's history. However, long-term archives of past atmospheric feldspar are not known. Here, we investigate feldspar mineralogy, content, and grain size in …

Earth Science: Sedimentary Rocks Flashcards

What three sediments does granite turn into after weathering? Quartz, Mica, Feldspar. What does feldspar turn into when it hydrolyzes? Clay; more feldspar closer to source of sediments. What is the end result of the weathering and transport of granite sediment? Quartz sand (sandstone facies), clay particles in suspension (shale facies) and ...

Sedimentary Rocks Flashcards

Generation - original rock weathers and produces smaller particles called clasts Transportation - clasts move by wind, gravity, ice, and water (bigger clasts require more energy to transport) Sedimentation - clasts pile up as energy decreases, only leaving dissolved rock particles (will be carried until the medium is saturated) Lithification - sediment turned into rock …

6.1: Clastic Sedimentary Rocks

Lithification is the term used to describe a number of different processes that take place within a deposit of sediment to turn it into solid rock (Figure (PageIndex{5})). One of these processes is burial by other sediments, which leads to compaction of the material and removal of some of the intervening water and air.
