  • Indiana Limestone - City University of New York

    INDIANA LIMESTONE. The limestone is soft and easily worked when quarried, but once the quarried rock dries it becomes case-hardened, that is, its surface becomes harder and more resistant to weathering. Indiana Limestone is a freestone, which means that it has no preferential direction of splitting.

    Marble

    Marble is a metamorphic rock consisting predominantly of calcite or dolomite. It is a metamorphosed carbonate rock (limestone or dolomite rock). Marble is a sparkling and typically granoblastic rock. Granoblastic rocks have uniformly sized, equidimensional, anhedral grains produced by recrystallization in a solid state (metamorphism).
