Thus, while the materials for producing, by diagenesis, the aluminous silicates just mentioned, are to be met with in the mud and clay-rocks of all ages, the chemically formed silicates, capable of crystallizing...

...pure enough to have given rise to the great beds of serpentine, pyroxene, steatite, labradorite, etc., which abound in the ancient crystalline schists. Thus,...silicates, capable of crystallizing into pyroxene, tale, serpentine, etc.. have only been formed under special conditions. The same reasoning which led... | |
