Chemical Sedimentary Rocks - Rock Around The World

Chemical Sedimentary Rocks. Chemical sedimentary rocks form by precipitation of minerals from water. Precipitation is when dissolved materials come out of water. For example: Take a glass of water and pour some salt (halite) into it. The salt will dissolve into the water. If you set the water in a hot and dry place (like Arizona) the water, but ...

2. Rocks Formed by Chemical Precipitates

Rocks which have been principally or entirely formed by chemical processes are, for the most part, of locally restricted extent, and are not at all comparable to the great masses of mechanical and organic sediments. This arises from the fact that the chemical processes occur in a conspicuous way only around the mouths of certain classes of springs (p. 191), and in closed bodies of water ...
