Remote sensing can aid surficial geological mapping and landform characterization. Unconsolidated surficial materials may also be given a lithology. The roots anchor the unstable surficial soil into the deeper stable layers or bedrock. This formation is an integral part of the surficial aquifer system. Quaternary surficial deposits are common and cover much of the bedrock throughout the park. An outwash plain might contain surficial braided stream complexes that rework the original deposits. Scotoplanes modify surficial elements in the ocean by moving through the sediment like a bulldozer. Mineralization in calcrete (calcium and magnesium carbonates) are the largest of the surficial deposits. Scalping screens are used to filter impure surficial pumice of organic soils and unwanted rocks. These surficial deposits unconformably overlay the much older Jurassic to Cretaceous-aged Franciscan Assemblage. The spectral vision allows identification of rock attributes for surficial mapping. The unique surficial structures can be observed as indicating the salt dome beneath the surface. Uranium was introduced into the coal-forming organic material in early stages by surficial waters. Langer Heinrich in Namibia is another significant surficial deposit. The plates' design includes a surficial laminate layer manufactured by 3M.
