Baraboo Quartzite

[2] Specimens of Baraboo quartzite may also display ripple marks that appear visually similar to the patterns one might see in the sand at a beach.

Ripples indicate that the sandstone from which the quartzite was metamorphosed was originally water-laid sediment.

[2] Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts.

Quartzite is a decorative stone and may be used to cover walls, as roofing tiles, as flooring, and stairsteps.

Formations of quartzite can be found throughout the Baraboo Hills in south-central Wisconsin.
