QUARTZITE #1

This is a typical quartzite. They are dense, hard rocks, generally uniform in texture, composed of fused quartz sand grains. Often they rock has a granular appearance on a weathered surface, but along a broken surface the sand grains are usually split. Also, unlike most of the nondescript rocks, quartzite …

Quartzite

Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts.Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite.

Quartz Vein

Quartz veins are mostly fracture related and have clear contacts with their host rocks. In metabasites, quartz crystals are smaller in veins hosted by massive eclogites and blueschists than in veins hosted by massive greenschists. In the former, the veins are generally thin (1–2 cm wide) and parallel the foliation S 1.

Dike (geology)

A feeder dike is a dike that acted as a conduit for magma. Magma flowed up then out of the dike onto the surface and formed another feature, typically a lava flow. In contrast to magmatic dikes, a sill is a magmatic sheet intrusion that forms within and parallel to the bedding of layered rock. Sedimentary dikes

Geology | Wisconsin DNR

Exposed outcrops of the quartzite that weren''t covered by the glacial ice pack were subject to freezing and thawing conditions. Water seeping into cracks in the quartzite expanded as it froze and eventually broke pieces of the bluff away. The thawing and freezing cycles also formed the piles of broken rock called talus on the slopes of the bluffs.
