When I was doing exploration activities in an area, I found minerals in the form of crystals and I was interested in capturing the blog. This is the Quartz minerals where the SiO2 formula.
The quartz has a crystal as illustrated, with the appearance of a brownish color and its glassy luster physical properties. Hexagonal crystal , shown like a cake "Carabikang" so this was make me interest to take the document photos.

Same shown make me interest.

I suspect the meaning of the mineral is that there is a chance of enough time and space for the formation of quartz with this kind of perfect crystal. So another thing is that the temperature at the time of its formation is at a very hot status, so that it reaches the situation that mineral Quartz can be formed, the temperature level at the freezing point of silica.

So I remember the Dana's minerals books that the quartz has detailed discussed so far, also on Wiki , Online Minerals and Geology sources.

Quartz = SiO2; Melting point above 1600&degC

Whats The point by above minerals, I think that the gold and others minerals can be associated in with this quartz. So also Pyrite, Sphalerite , I found at the same place,

What my logic is thinking is that hot minerals have flowed in this host rock zone, so minerals that are lower in temperature may also flow with Hydrothermal liquid during the construction of rock formations.

For the gold exploration, mostly to find out the associated of sulfide minerals rather than pyrite, sphalerite, azurite, malachite, and silica.

What are use of Silica

Quartz content a mineral Silica, so that there knowledge much more known in the public as silica useful to peoples activity.

Silica sand use for the glassware. On these industry need a high quality purity of the content of Si. So that to be find out of the sources is quite many competitive in the world.

Silica as a product absorbtion, is the silica gel. This product as ball form of the silica so that can be as absorber of the humidity.

Silica also be a Sollar Cell, as for this , the structure of these Si as a Hexagonal shape, so that can absorb the maximum of the Sun light.

Silica as the silica sand for the industry like water purifier, Ceramic, Glassware etc

Silica as Silica sand useful to the construction material as in mixing with cement, also in using the metalloid metallurgy.

How is the Silica in the nature

In the nature these silica is as quartz mineral or as a quartz vein on the rock formation. Generally close to the geology structure fault, joint and shearing area at the host rock.

The silica and quartz also close to the zone of mineralization. The character of these silica melting point is so high, so the heating efect cause more lowest minerals follow again Silica.

That why , if you find quartz vein, can be as indicator for others mineral near this outcrop. But need more others knowledge...

Silica almost in all the various of rocks in the formation. All the igneous rock content Silica, almost most of the rock compilers in the earth's crust are composed of Silica. All volcanic products contain this mineral, so as to produce a lot of silica sand deposits in each mountain channel.

Igneous rocks, sedimentary rocks also in metamorphic rocks there are silica minerals. Although not as quartz itself, but mixed with other compounds chemically. This proves that silica as dominant in this world as a constituent part of the earth's crust and also the basic ingredients of magma.
