This unit is a cherty dolomite where the effect of chert (density higher than neutron density) is confounded by the effect of dolomite (neutron higher than density porosity). Limestone is made up of mainly calcium carbonate and as a natural, sedimentary rock, its unique texture and structure as well as its color depends on where it crystalized and where it is quarried. Natural limestone originally deposits in shallow sea beds and the color ranges from white, yellow, and gray to blue, beige, and cream. While the limestone color …On the flanks of the basin the cherty beds are intercalated with wedges of pure crinoidal limestone that formed in the shallow near-shore water.
