What type of sedimentary rock is formed when minerals fall out of solution?

The main idea here is how sedimentary rocks form. When minerals are dissolved in water and later come out of solution, they precipitate as solid crystals and accumulate to make rock. This process creates chemical sedimentary rocks, such as halite (rock salt) or gypsum, and even some limestones formed by dissolved minerals crystallizing. Clastic rocks form from fragments produced by weathering and erosion that are transported and then lithified into rock. Organic rocks come from the accumulation of plant or animal material. Metamorphic rocks arise from existing rocks transformed by heat and pressure, not by precipitation from solution. So the type formed by minerals falling out of solution best fits chemical sedimentary rocks.
