When excavating a field of Quaternary alluvium (modern sediments), a layer of limestone bedrock is encountered. The limestone is found to have been intruded by an igneous dike. Both the limestone and the dike are fractured by a fault. Place these features in order from oldest to youngest: Igneous dike, limestone bedrock, quaternary alluvium, fault.The Quaternary evolution of an alluvial fan system in the Himalayan foothills reveals two distinct phases. The Early Quaternary Siwalik system (I) and the Late Quaternary intramontane piggy-back system (II) have been studied in detail in the Subathu sub-basin of NW Himalaya (with system I followed by system II). Quaternary Geology is mapped without regard for any organic soil layer that may overly the deposit. The Connecticut Quaternary Geology information was initially compiled at 1:24,000 scale (1 inch = 2,000 feet) then recompiled for a statewide 1:125,000-scale map, Quaternary Geology Map of Connecticut and Long Island Sound Basin1.2. Study area2.1. Gulf of Mexico. Gulf of Mexico is a partially landlocked body of water on the southeastern periphery of the North American continent and the coastal part of the Gulf of Mexico is classified as a transgressive and wave-dominated coastal system (cf., Boyd et al., 1992).The outcrops along the western Gulf of Mexico includes: (1) …

Most sedimentary material that fills a basin ("basin fill") that is not lithified is typically lumped together as "alluvial". [9] Alluvium of Pliocene age occurs, for example, in parts of Idaho.
