1 Sapphire blue is a cool color. 2  Sapphire carries the blue symbolism of importance and confidence. 3  Although it's not a light or pastel blue, it still has something of a fresh, spring-like quality with a touch of childlike playfulness.
Sedimentary rocks make up only 5% (by volume) of the upper 10 miles of the crust, but about 75% of the outcrops on the continents. Two primary types of sedimentary rocks: 1  Chemical-precipitate from solution (e.g., limestone); most important constituents are calcite, dolomite, chalcedony (SiO2), gypsum, and halite.2  Chemical sedimentary rocks can be further divided as to: 3  inorganic (e.g., limestone, rock salt, dolomite).

   Sedimentary rocks can also be formed when minerals are dissolved in  water and are then resolidified. This type of sedimentary rock is  called a chemical sedimentary rock. Oolitic limestone is a good  example of this type of sedimentary rock.1 person found this useful.gneous rocks are made from magma. Magma is made of melted rocks.  (When it is underground it is called magma, when it erupts on the  surface of the earth, it is called lava â¦ . It's the same material  though.) When magma/lava cools, it forms igneous rocks.
