At several mines, after the lower Tyrone and Oregon reserves were exhausted, an inclined slope was driven down into the underlying Camp Nelson Limestone to produce stone from another interval in the High Bridge Group, bypassing deleterious argillaceous limestone and shale in the uppermost Camp Nelson. Thus, on some properties in central ...

en This interpretation is supported by the presence of fine, alternating laminae of light grey argillaceous limestone, or calcareous shale, and dark grey silt to sand-rich calcareous shale, as observed in thin section, and the characterization of the lithology for the vertebrate-bearing strata as an interlaminated argillaceous limestone and calcareous shale.

The American Natural Cement Revival. ... White sought, and soon discovered, a similar argillaceous limestone in Fayetteville, N.Y. When burned and then ground to a fine powder, the rock yielded a hydraulic cement offering fast setting, moderate strength and excellent durability. The material was originally called "water lime" because it set ...

As limestone is composed of finer grains so its density is more as compared to that of sandstone, and so pores in the sandstone are more Limestone, like marble and other calcareous stones, are referred to as acid sensitive.

An argillaceous limestone unit exhibits intermediate conductivity. The lower permeability of the peripheral rocks relative to the interior rocks may best be explained by the effects of karst evolution: (1) dissolutional enhancement of horizontal hydraulic

Lithologically the allochthonous rocks are mostly composed of sandstone, siltstone, greensand, siliceous mudstone, argillaceous micritic limestone and rare coal measures along with dispersed organic matter.

They are dominantly calcite limestone, are rarely dolomitic, and tend to be argillaceous, meaning that they tend to contain some clay minerals. Typically, the limestone units are relatively thin and are separated by shaly strata of comparable thickness.

Argillaceous minerals may appear silvery upon optical reflection and are minerals containing substantial amounts of clay-like components (Greek: ἄργιλλος = clay). Argillaceous components are fine-grained (less than 2 µm ) aluminosilicates, and more particularly clay minerals such as kaolinite, montmorillonite - smectite, illite ...

Dolomite and limestone are similar rocks. Both are sedimentary carbonates with many near-identical properties.
