Chapter xvii building stone and gravel stone Building stone is relatively scarce in our East Texas area and the only stone of value is sandstone, of which there are two classes. Brown sandstones which are altered glauconitic sands or sands cemented by ferruginous cement. Gray sandstones with calcareous or siliceous cement. The brown sandstones are found almost entirely in connection.with the Marine beds. In some places the altered greensands are of sufficient hardness to be quarried and are used occasionally where other rock is scarce for building foundations and chimneys. At other places the sand beds have been cemented by ferruginous solutions and hardened into good beds of sandstone. The gray sandstones are by far the most abundant and are found in Fayette, Jackson and Corrigan. Some of them have a calcareous cement, but probably the greater part have a siliceous matrix. No limestones suitable for building are known in the area. sandstone of the marine--brown sandstone The most important of these sandstones are a series of local and limited deposits formed by the action of ferruginous solutions on the original loose sands. This varies from a comparatively soft friable mass to a compact hard and flinty rock; from yellow to very dark brown in color, and from one to twenty feet thick. Such rocks are found everywhere throughout the East Texas region, and are often used for foundations and chimneys. They ovcur plentifully in the bluffs of the Angelina at the mouth of Walker creek, and on the Neches river west of Gent, in the shape of a soft friable sandstone. The State Penitentiary at Rusk is built of a soft yellow sandstone, containing specks of altered glauco
