Burlington Limestone- gray, fossiliferous limestone and darker gray dolomite; white and gray mottled fossiliferous chert, locally contains dolomite crystals; two widespread glauconite zones; basal sandstone locally in southeastern Iowa. Approx thickness 80 ft.Limestone and dolostone are collectively referred to as carbonates because these two sedimentary rock types consist mainly of the minerals calcite (CaCO3 ), aragonite (CaCO 3 ), and dolomite [CaMg (CO 3) 2 ]. The term dolostone, proposed to specifically refer to the rock type composed of the mineral dolomite, has not gained wide usage, and ... The lower ironstone sequence comprises four ironstone facies namely: a) lagoonal/tidal flat mud-ironstone facies, b) lagoonal fossiliferous ironstone facies (proximal tempestite), well developed in the southern sector of Gabal Chorabi mine area, c) shallow subtidal-intertidal nummulitic-ooidal-oncoidal ironstone facies, dominated in the ...
