WebBedding is the arrangement of sedimentary rocks in beds or layers of varying thickness and character. A bed (or stratum) is a relatively conformable succession of genetically related laminae or lamina-sets (Campbell, 1967) bounded by surfaces (called bedding surfaces) of erosion, nondeposition, or their correlative conformities.The bed is the smallest formal … WebDec 31, 2024 · A tight, recumbent fold in the Sierra de Juarez, Mexico, shows both upright and up-side-down bedding. Way-up (or “geopetal”) structures allow us to tell the two apart. In such situations, we need reliable tools in order to accurately interpret which direction was “up” when the rock originally formed.
