Collection of minerals. #Photography #Geology
On this occasion I present my collection of minerals. Since I was a child I was fascinated by Geography and fate gave me the opportunity to study it and in my training as a geographer I have learned a lot of things, as a geographer we learn from many sciences and subjects. Geology has been one of those and I have become more passionate.

Minerals
Quartz
Chemical composition: (Si O2)
It is a mineral that belongs to the group of silicates, it is one of the most abundant on earth after feldspar. It crystallizes in the hexagonal system, has a vitreous shine and is translucent in its purest state. It is one of the hardest minerals (7 in the scale of Mosh: able to scratch most minerals) and resistant to weathering, hence its abundance.
Amethyst Quartz
Chemical composition: (SiO2 Fe+3)
It is a variety of quartz, purple with a beautiful glassy luster. It is considered a precious jewel. One of the characteristics of this mineral is its ability to change a little color when subjected to high temperatures. As I said, it has the same characteristics as quartz: chemical composition, hardness (7), but the difference is that it has a greater amount of iron and that is what determines the coloration of the mineral.
Pink Quartz
Chemical composition: (Si O2)
It presents the same physical and chemical characteristics of quartz, but with a pink hue, due to the presence of other minerals. It has a salmon pink tone.
Pyrite(FeS2)
Chemical composition: (FeS2)
This curious mineral belongs to the group of sulfates, is an iron sulphate and is considered "the gold of fools" because of its physical similarity to gold. Both have a beautiful yellowish metallic sheen. They differ in their chemical composition completely and in the crystalline system to which they belong. Pyrite crystallizes in the cubic system, and gold does not form crystals precisely. In addition, pyrite has a characteristic smell of sulfur.
Muscovite
Chemical composition: (KAl2(AlSi3O10)(OH)2)
It is a very common mineral, which belongs to the large group of Silicates (Filosilicates) and within this to the famous group of micas. It is an aluminosilicate of potassium and aluminum. It differs from other micas such as biotite (black) or chlorite (green) because of its color, in fact it is colorless, white or silver. It crystallizes in the monoclinic system. It is very fragile, has hardness 2 on the scale of mohs, and has a perfect exfoliation, bone breaks into very thin sheets.
Tourmaline
Chemical composition:(Na,Ca)(Al,Fe,Li)(Al,Mg,Mn)6(BO3)3(Si6O18) (OH,F)4
This mineral has a complex chemical composition, belongs to the group of silicates. It crystallizes in the trigonal system, with a high hardness (7), and has a great variety of colors. The best known in black with presence as striations and chrome green, which is used as a precious jewel after polishing.
Iron
Chemical composition: Fe
It is a pure native element, although rarely found alone, it is usually associated with other minerals or rocks, it is one of the most abundant pure elements on earth, only after aluminum. It is a malleable metal, silver, and as many know, has magnetic properties.
Granodiorite
Chemical composition: Cuarzo (Si O2) - Feldspates- Biotite
This is not a mineral, it is a rock, that is, a composition of several minerals. The granodiorite is a plutonic igneous rock, bone is magma cooled in millions of years and crystallized at depth. It has a resemblance to granite, but they differ in the percentage of minerals they contain, they have more plagioclase than ortosa (Feldspatos) and the micas act as a secondary mineral, while in granite they are principal.
In the photograph a granodiorite is observed, belonging to the batolito del carmen in the state of Merida, Venezuela. I got it very close to my house, it is known in Merida as "the granodiorite of carmen." There is a large amount of feldspars and quartz (white) and in lesser quantity micas.This rock is a bit oxidized due to weathering.
Geode
A geode is a rock that contains a cavity where the walls are covered with crystallized minerals, commonly quartz. They are incredible and beautiful, some like those in photography resemble a universe. This contains small quartz crystals.

I saw your post on the Whaleshares Curation Show. Congratulations on the feature!
I was quite a rock collector as a child and still have part of my findings to this day. I even have a giant chunk of rock that I am certain is filled with quartz. I found it in Montana and packed it up in my car and drove it back to California.
Your post was very informative. Thank you for sharing!
Sweet! I love having crystals and rocks around me. I've loved them ever since I was a little kid.
looks really cool! Very informative. Upvoted :)
Hey @apple96, I am a curator of the Whaleshares Curation Team. I have selected your post to be presented in a live curation discussion on Monday 16th April. Your post will be awarded a 100 Whaleshares vote on the night. I do hope you can come along and spectate. The event will be held in The Curation Lounge on the Whaleshares server.
Here is a post from last weeks show that explains things:
