Explore the formation, classification, and significance of sedimentary rocks in this comprehensive 38-minute lecture. Delve into the origins of sedimentary rocks, examining detrital, chemical, and organic types. Learn about particle size categories, shale, sandstone, conglomerate, and breccia. Investigate biochemical and inorganic limestones, evaporites, and coal. Understand the processes of diagenesis and lithification that transform sediments into rock. Discover how sedimentary rocks represent past environments and provide valuable information for interpreting Earth's history through various sedimentary structures and strata.

Syllabus
Earth Science 15th Edition
Origins of Sedimentary Rock
Detrital Sedimentary Rocks • Detrital sedimentary rocks form from sediments that have been weathered and transported - Chief constituents of detrital rocks include clay minerals
Particle Size Categories
Detrital Sedimentary Rocks • Shale - Silt- and clay-sized (fine-grained) particles - Form from gradual settling of sediments in quiet
Detrital Sedimentary Rocks • Sandstone - Sand-sized particles - Forms in a variety of environments - Second most abundant sedimentary rock - Quartz is the most abundant mineral
Quartz Sandstone
Detrital Sedimentary Rocks Conglomerate and Breccia - Conglomerate consists of rounded, gravel-sized (or larger)
Biochemical Limestone
Inorganic Limestone
Chemical Sedimentary Rocks • Evaporites
Salt Flats
Coal: An Organic Sedimentary Rocks
Turning Sediments into Sedimentary Rock: Diagenesis and Lithification
Classification of Sedimentary Rocks
Sedimentary Rocks Represent Past Environments
Sedimentary Environments
Sedimentary Structures . When present, they provide additional information for interpreting Earth's history • Types of sedimentary structures - The layers of the sedimentary rocks are called strata or
