If such adiabatic freezing were to control the ascent of hydrous mafic magmas, basalts would probably never erupt in volcanic arcs. |
These lands less productive and fragile ate very sensitive to hydrous and wind erosion. |
This system often leads to lands fertility loss due to hydrous erosion, to silting up and alkalization. |
A complex system of pipeline water of rain collected then in large impluvia was useful for the hydrous provisioning of the area. |
Tourmaline is a complex hydrous silicate of aluminum and boron, with varying amounts of magnesium, iron, and alkalies. |
These had the refractive indices and gave the chemical reactions of lazulite, which is a hydrous phosphate of aluminum, iron and magnesium. |
