Siltstone is a sedimentary rock composed mainly of silt-sized particles. It forms where water, wind, or ice deposit silt, and the silt is then compacted and cemented into a rock. Silt accumulates in sedimentary basins throughout the world. It represents a level of current, wave, or wind energy between where sand and mud accumulate.Composition: Quartz. Rock Type: Clastic. Other Notes: Does not react with acid.

Jan 25, 2023 · Common Minnesota Rocks. Throughout geologic time, Minnesota's landscape has undergone many changes. At times, high mountains lined the horizon. Later, vast seas engulfed the region. Still later, great sheets of ice covered the land. All of these environments are recorded in the rocks and sediments found around the state. The pre-existing rock is called either the parent rock or the protolith. Your textbook incorrectly uses the term “source rocks” for the pre-existing rock. The term source rock used in sedimentary deposits to describe the rock from which petroleum is derived, or the rock that erodes to produce sediment and later sedimentary rock.FlexBook Platform®, FlexBook®, FlexLet® and FlexCard™ are registered trademarks of CK-12 Foundation.Action Plan (LCCAP 2017-2025).
