Brecciated limestone

M Gr, dense to sublithographic, wavy laminated, brecciated limestone (lagoonal)... 

Brecciated limestone was formed from coarse angular fragments. 

Finally, I describe the main locality situated in the eastern quarry of the hill, which Kormos called the bone-brecciated pillar and Kretzoi termed locality no. 2 of Nagyharsanyhegy. Kormos collected there briefly in 1916, then Kretzoi and myself in 1953 and 1955. This residual pillar of the steeply slanted (at an angle of about 120-130°), tectonically preformed karstic hollow embedded in Malm limestone has since been demolished, but its continuation in the present layer of the quarry contained enough material for the author and his colleagues to obtain smaller collections from 1973 to 1975 (presently known as the artist colony quarry ). 

Colorado, is hosted in folded and brecciated Mississippian dolomite, shale, sandstone and coal, which is in fault contact with Precambrian gneiss. The Precambrian gneiss is anomalously enriched in uranium, and a Mesozoic or Caenozoic age of mineralization in the Mississippian host rocks, formed by downward percolation of uraniferous groundwater from the adjacent Precambrian terrain, is inferred. Mineralization in the Pryor Mountains region, Montana, is hosted in karsts developed with the Mississippian Madison limestone and consists of uraninite-tyuyamunite grading up to 7% UsOg associated with clay minerals and silicified collapse breccias. A Caenozoic age of mineralization, under conditions similar to those of Pitch mine, is favoured.
