Sedimentary Rock The Canadian Encyclopedia

Sedimentary Rock. Sedimentary rock, one of the 3 major classes of rock comprising the Earth's crust (the others being igneous and metamorphic), is made up of loose, unconsolidated sediment that has been transformed into rock (ie, lithified) during geological history.. Only about 5% of the Earth's crust is composed of sedimentary rocks

From huge landslides, to violent volcanic eruptions to meteorite impacts, whenever something catastrophic happens there is a breaking, propelling and deposition of material.

Our knowledge of Earth's primitive surface environment is limited by the very few outcrops of demonstrably sedimentary rocks we have available. The Nuvvuagittuq Greenstone Belt (NGB) is an Eoarchean/Hadean volcano-sedimentary assemblage emplaced prior to 3.75 Ga (Cates and Mojzsis 2007) and likely as early as 4.28 Ga (O'Neil et al. 2008).
