Conglomerate. Which of the following best describes bedded gypsum and halite? Chemically derived sedimentary rocks. Which of the following descriptions best matches a "greywacke"? A sandstone with sand grains embedded in a clay-rich matrix. What mineral is the building block of microcrystalline flint, chert, and jasper? Gray to tan, cherty limestone of Kaibab and Toroweap Formations, and underlying white to tan, fine-grained Coconino Sandstone. Limestone was deposited in a shallow sea, and sandstone was deposited in near-shore dunes and beach settings.

It is proposed that many nodular cherts in limestone have formed in the ground water of mixed meteoric-marine coastal systems where dissolution of biogenic opal and mixing of marine and fresh waters can produce waters highly supersaturated with respect to quartz and undersaturated with respect to calcite and aragonite.
