Rocks and minerals play a valuable role in natural systems such as providing habitat like the cliffs at Grand Canyon National Park where endangered condors nest, or provide soil nutrients in Redwood where the tallest trees in the world grow. Rocks and minerals are important for learning about earth materials, structure, and systems.

The term siliciclastic refers to sediments composed mostly of silicate minerals. The most common sedimentary rocks – including shale, sandstone, and conglomerate – form from siliciclastic sediments. Other kinds of sedimentary rocks consist of carbonates (in limestones), iron oxides and hydroxides (such as hematite or goethite in iron formation), or other minerals.

Oolitic sand is an unusual sediment that is found in and around the Great Salt Lake. Instead of forming from grains of mineral fragments washed down from higher ground, this sand formed within the Great Salt Lake. It is composed of tiny, lightbrown, rounded oolites. An oolite has a shell of concentric layers of calcium carbonate that precipitated around a nucleus or central core.

Sandstones are a type of clastic (terrigenous) sedimentary rocks deriving, as the name suggest, from the consolidation of sandy sediments. Sand consists of clastic particles produced by the erosion of pre-existing rocks with grain size comprised between 0.0625 and 2 mm. The upper boundary of 2 mm arbitrarily separates sand (and sandstones) from the coarser gravel and …
