Question
In Bowen’s Reaction Series, note that Olivine is formed at very high temperatures and pressures, whereas, quartz is formed at temperature/ pressure conditions closer to the surface conditions. What patterns do you see in silicate mineral Silica strcture them Olivine? Why?

First of all we need to understand the understand the concept of the bowen reactions series and then only we will able to understand the pattern of the silicate in the elvated temperature and the pressure conditions. so lets begin with this as follow-
Bowen reactions series can be defined as it is the specific minerals form at the specific temepertaure as the magma cools down. at the elevated temperature it is assocoiated with the intermediate form of the molten magma. the series enable us to determine the specific pattern of the crystal formations of the minerals from the molten magma when they are in the solid and cold state. this is form in the series formate and thus named as the bowens series of reactions. during this crystal formations some reactions also take place with the recations of the gases present in the atmosphere.
Now lets move to the pattern of the crystal of the silicate minerals in this. as under the elevated temperature and the pressure conditions of the crust and the mentle, silico and the oxygen combinedly form the complex ion which have the crystal geometry of the tetrahedron shape and the crystal structure. in this tetrahedron pattern of the crystal strcuture we have the silicon at the center and the 4 oxygen atoms at the four corners of the molecule. thus it will have the tetrahedron crystal strcuture.
But it can also show the variations in the crystal structures as it have the ability to show variations if there is a variations in the temperature and the pressure. it will have the 6 different types of the pattern as isolated tetrahedron, tetrahedron forms of rings, tetrahedron chains, ribbons of tetrahedron, sheet pattern. example- quartz and feldspar.
