10.3: Identifying Sedimentary Rocks - Geosciences LibreTexts

 · Chemical Sedimentary Rocks form from the inorganic precipitation of minerals from a fluid. If the ions present within a fluid (water) become very concentrated either by the addition of more ions or the removal of water (by freezing or evaporation), then crystals begin to form. In this case, the identification of the type of sedimentary rocks is ...
