Natural Countertop Geology and Stone Identification Marble

Sandstones are also sedimentary rocks that are primarily quartz minerals loosely cemented together with calcite, iron oxides and/or mud. Sandstones are frequently used as a dimensional building stone. Major cities throughout the world contain buildings made with sandstone. Some common sandstone is brownstone and shale.

PORTLAND BROWNSTONE City University of New York

The red color is due to iron oxides. Freshly quarried sandstone tends to be yellow-brown due to the presence of limonte. Dehydration of the quarried rock due to extended exposure to the air, results in conversion of limonite (FeO) to hematite (Fe2O3). The distinctive red-brown color of brownstone is due to the presence of hematite.
