Porphyret: species, properties and application

Porphite Stone is a mountain volcanic breed. A characteristic feature of this mineral is that there is no such element in its chemical composition as quartz. But thanks to the wide list of positive qualities, porphite is used in the most diverse spheres of human activity.

In the article, we consider in detail how the stone looks like, what is its chemical and physical properties, as well as what kind of porphyritis varieties exist in nature. We will get acquainted with all its distinguishing features, features and characteristics.

What it is?

Porphyrites are called minerals having a porphy. This means that this rock has a non-uniform grain structure consisting of relatively large inclusions. Ideally, porphite is a durable gray-brown stone. However, the gray color is not always uniform – often in the structure of the mineral you can see a large number of inclusions and inclusions that can have a wide variety of shades (yellowish, pinkish, white and others).

As for the physical and mechanical indicators of this mineral, they are as follows:

  • The share of the stone is calculated in 1.45-2.5 kg / cm3;
  • The density is 1450 kg / m3;
  • Specific heat capacity – 0.83 kJ / kg * to.

Moreover, the last indicator is quite large in the use of porphyritis in the baths and parilots.

Origin and field

Porfire is a mineral that is formed by naturally. If we talk about the nature and method of its origin, then it is formed only in one case – during microlyte processes, which are characteristic of the basic formula of Lava. And the lava should be near the day surface. Porphite refers to the category of secondary metamorphiced breeds. From the composition of this mineral, thanks to the processes of epidotization and chloritization, perlite is supplanted.

Deposits of this stone are widespread worldwide. So, the largest developments of the mineral can be found in various countries and regions. This is:

  • Caucasus;
  • Siberia (Eastern regions);
  • Altai;
  • Far East;
  • Kazakhstan;
  • Ukraine;
  • Bashkortostan.

Stones found in different fields can vary significantly in their properties. It should be considered when applying porphyritis.

Due to such widespread in the market and in stores, Porphite can be found in very affordable prices, which ensures the availability of the mineral for almost all social segments of the population.

Composition and properties

According to its texture, porphite is quite durable and solid material. If we talk about the composition of the stone, it should be noted that its internal layers may include such elements as:

  • plagioclase;
  • aluminosilicates;
  • chlorite;
  • Biotites and others.

    The chemical composition of the stone is also not homogeneous. The composition of the mineral rock includes such components and compounds as:

    • silica (its volume is half of the total composition);
    • aluminum oxide (about 20% of total);
    • iron oxide (is about 10%);
    • Calcium oxide (about 10%).

    However, some malicious compounds may include some malicious compounds, such as sulphides that can harm the human body. In order to detect them with a naked eye, it is necessary to look at the surface of the mineral – if you have noticed a large number of plugs of a metal or golden shade, then it is better to give up from the purchase of such a stone.

    The melting point of porphyritis is quite high, it is impossible to achieve in vivo. This indicator is about +1 200 degrees Celsius.

    Having such a rich chemical composition, porphite is endowed with a large number of positive characteristics that are highly valued when using mineral.

    It is believed that it is able to have a beneficial effect on the human body. So, it has the ability not only to facilitate the course of certain diseases, then also act as a prophylactic and relaxing agent. Thanks to this characteristics, the material and got widespread.

    Among such properties can be allocated:

    • saturation of the atmosphere favorable for the human body substances;
    • normalization of blood pressure;
    • restoration of the working capacity of the circulatory system (in particular, vessels);
    • prevention of kidney diseases, as well as diseases associated with the urogenital system;
    • treatment of headaches;
    • facilitating the respiratory process;
    • Creating a Relaxation and Relaxation Effect for the Body.


    Despite the fact that the porphite itself is a rather unique stone, depending on the chemical composition and structure, as well as the external color, scientists have allocated several types of unusual mineral.

    Mineral has unique in nature by physical and chemical properties that must be considered in the case of the use of stone. There are several varieties of porphyritis, which differ not only in appearance, but also by the inner structure, respectively, depending on the specific species of the volcanic rock, its properties may vary.

    Consider each of them in more detail.


    Thanks to the name of this specification, we can conclude that a large number of basalts are included in the mineral. However, besides him, a different element can be detected in basalt porphyritis in particular, in particular.


    Diorite variety of porphyritis contains a large number of additional elements: plagioclase, biotit, pyroxen, amphibole. As for the colors of stones belonging to this category, it can be very diverse: from bright scarlet and crumb flowers to less pronounced shades of graphite and marsh.


    If we talk about the structure of the stone of this type, here the main volume is pyroxen and plagioclases. Color Pretty Uniform – Gray or Black. However, shades and subtones can change.


    This category is different from all others with its fine-grained. Often in the composition of diabase stones there are additional splashes of porphyry type, as well as Albit. The colors of the stone are in the range of a rather dark and muted palette of brown and gray shades.

    Pyroxena view

    The composition of the porphyrita of this species does not include such malicious components as radionuclides. Inside the stone, in general, there are no worst of malicious connections. But in Pyroxen Porphyirite, such components like magnesium, silicon and calcium can be distinguished.

    Nature presented us a few varieties of porphyritis, differing in their appearance and inner composition, which, in turn, determination of the properties of the stone.

    As used?

    This mineral stone is highly appreciated and quite often used, being quite important and necessary stone for a person.

    Given all the unique positive properties that Porphite possesses, he found wide use in various spheres and areas of human activity.

    Obviously, this is most often this stone (even if the root) is used for a bath or sauna. In particular, they are usually filled with chambers (special furnaces) in these rooms. Such use of rock is due to:

    • favorable properties that are able to provide porphite on the human body;
    • Physical properties of breed.

    Since the stone is quite strong, it is able to withstand the oscillations and jumps of the temperature regime, while not breaking and not destroying, but maintaining its structure and integrity.

    And also porphite is actively used for construction purposes at the expense of its physical characteristics, in particular, hardness. Moreover, such a building material can be used both in a purely private and domestic and large-scale industrial and civil construction. For example, pedestrian walkways in many parks posted precisely through this stone. Mineral can be used for facing facades and bases of various buildings and structures.

    Another area of ​​using a volcanic mineral – interior design and premises. Thus, the specialists of this industry prefer porphyritis due to its resistance (porphite is an acid-resistant material). With this mineral, a variety of ornaments and drawings are laid out on a variety of surfaces. They can be a natural color of porphyritis, but also stone can and paint.

    One of the unique properties of the stone is his self-purification. Due to this property, it is often used for powering gas stations and storage sites for petroleum products.

    Porfire is a stone that is widely prevalent, many of us meet and use it in everyday life, not knowing it. It is its use in medicine, while visiting a bath, for cladding and many other.
