Overview
Learn about sedimentary structures, including laminations, cross bedding, ripples, graded bedding, growth bedding, and mud cracks. The course covers the definition of beds, strata, and laminations, as well as the geometry of bedding. It discusses various types of sedimentary structures and their formation in different depositional environments such as calm waters, deserts, marine settings, and fluvial environments. The course also explores the significance of different types of ripples, climbing ripples, heterolithic bedding, graded bedding, growth bedding, and mud cracks. The teaching method involves a detailed explanation of each structure with examples and visuals. This course is intended for geology enthusiasts, students, and professionals interested in sedimentology and stratigraphy.
