brown pyroclastic with porphyrite
Pyroclastic is a porous, light pyroclastic rock formed by rapid cooling after the eruption of basaltic magma. Black, dark gray or brown (depending on the degree of oxidation). Rich in pores (bubbles), loose texture, low density. Basalt, containing pyroxene, plagioclase and other dark minerals.
Mica
Mica (mica) is a rock mineral, is made of potassium, aluminum, magnesium, iron, lithium and other layered structure of aluminum silicate. Its English name mica comes from the Latin micare, which means "shiny. In ancient China, mica was called "Tianpi" and "Dijin", and Tianpi Mountain, the origin of mica in Inner Mongolia, was named after it. Polytypic mica is prevalent, of which monoclinic is common, followed by trigonal, and the rest are rare. Mica is usually false hexagonal or rhombohedral plate, flake, columnar crystal form. The color varies with the change of chemical composition, mainly with the increase of Fe content. The characteristics are insulation and high temperature resistance.
diorite
Diorite is a representative rock of neutral deep crystal rock, and it is also one of the main rock types in granite stone. It is mainly composed of plagioclase (medium-more feldspar) and one or several dark minerals, of which the total amount of dark minerals is generally about 20-35%. No or only a small amount of potassium feldspar, generally not more than 10% of the total feldspar. Does not contain or contains very little quartz, the amount of which does not exceed 5% of the total amount of light-colored minerals. Dark minerals are mainly amphibole, sometimes pyroxene and biotite. The accessory minerals are mainly apatite, magnetite, ilmenite and titanite.
synenite
It is a kind of magmatic rock, which belongs to neutral deep intrusive rock. light gray, with grainy, porphyritic structure. The content of silica (about 60%) and the diorite is quite, but the alkali (sodium oxide, potassium oxide) is slightly higher than the diorite. It is mainly composed of feldspar, hornblende and biotite, with no or very little quartz. Alkaline feldspar (usually orthoclase, microcline, striated feldspar) accounts for more than 70% of the feldspar. It is often a small rock strain, which forms a complex with basic rocks and alkaline rocks.
The orthostone of the alkaline massif
Syenite is a kind of magmatic rock, which belongs to neutral deep intrusive rock. light gray, with grainy, porphyritic structure. The content of silica (about 60%) and the diorite is quite, but the alkali (sodium oxide, potassium oxide) is slightly higher than the diorite. It is mainly composed of feldspar, hornblende and biotite, with no or very little quartz. Alkaline feldspar (usually orthoclase, microcline, striated feldspar) accounts for more than 70% of the feldspar. It is often a small rock strain, which forms a complex with basic rocks and alkaline rocks.
Syenite in alkaline rock mass
Syenite is a kind of magmatic rock, which belongs to neutral deep intrusive rock. light gray, with grainy, porphyritic structure. The content of silica (about 60%) and the diorite is quite, but the alkali (sodium oxide, potassium oxide) is slightly higher than the diorite. It is mainly composed of feldspar, hornblende and biotite, with no or very little quartz. Alkaline feldspar (usually orthoclase, microcline, striated feldspar) accounts for more than 70% of the feldspar. It is often a small rock strain, which forms a complex with basic rocks and alkaline rocks.
calcite
Calcite (Calcite) is a common calcium carbonate mineral with a chemical formula of CaCO. It is widely found in sedimentary rocks, metamorphic rocks and igneous rocks. Calcite has unique optical properties such as birefringence and birefringence. Veins usually form when calcite is intergrown with ore minerals. In these veins, calcite may be the main component, but may also contain other valuable ore minerals, such as pyrite, sphalerite, barite, etc. These ore minerals are usually formed in low temperature hydrothermal veins.
Cabin Creek Meteorite
The Cabin Creek meteorite is a well-known iron meteorite that landed in Arkansas, United States, in 1886. It belongs to Class IIIAB iron meteorites with a mass of about 48.5kg. The directional landing characteristics of this meteorite are very obvious, with different depths of air marks and flow lines on the surface, and it maintains a fixed flight orientation when passing through the atmosphere.
Basalt of the Canary Islands, Spain
Basalt is a volcanic magmatic rock with relatively low silicon content. The rock is usually dark black. This basalt has no visible crystals. Therefore, it is made of volcanic glass and microlith (crystals that cannot be distinguished by the naked eye).
fault breccia
Fault breccia is formed in the fault zone. They consist of angular rock fragments from rocks on either side of the fault. These angular detritus elements are usually surrounded by cements, usually calcite or siliceous, which are deposited in pores created by fragmentation caused by fault replay.
Syenite in alkaline rock masses
It is a type of magmatic rock that belongs to neutral deep-seated intrusive rocks. Light gray, with equigranular and spotted structures. Its silica content (about 60%) is comparable to diorite, but its alkaline content (sodium oxide, potassium oxide) is slightly higher than diorite. It is mainly composed of feldspar, amphibole, and biotite, with little or no quartz. Alkaline feldspar (usually orthoclase, plagioclase, and plagioclase) accounts for over 70% of feldspar. Often appearing as small rock masses, it forms a complex with basic and alkaline rocks.
Weinsberg granite
Weinsberg granite is a type of granite named after the Weinsberg region in Germany. Usually appears gray or light pink with small black spots. Widely used in architecture and decoration, such as flooring, countertops, and monuments. It has a long history of use in architecture and sculpture, and is favored for its beauty and durability.
Stannern meteorite
Stannern meteorite is a type of achondrite belonging to the HED meteorite, originating from asteroid 4 Vesta. The meteorite fell around 6am on May 22, 1808, in the village of Stona ř ov in Moravia, Czech Republic today. These meteorites are mainly composed of silicate minerals such as pyroxene and plagioclase, similar to basalt on Earth. The total weight of the meteorite is about 52 kilograms, with the largest fragment weighing 6 kilograms. This is the largest fragment preserved in the Vienna Museum of Natural History.
serpentine
Serpentine is a general term for a type of magnesium rich silicate mineral that contains water, such as serpentine, serpentine, and fibrous serpentine. Their color is usually green, but there are also shades of green, light gray, white, or yellow. Serpentine stones are named because they are often green and green in color, resembling snake skin. Serpentine rocks are often distributed at the top of larger ultrabasic rocks in a cap like or edge like manner, and sometimes in a vein like or irregular shape. Smaller rock masses often completely erode into serpentinite. The minerals related to serpentinite include chromium, nickel, cobalt, platinum, asbestos, talc, magnesite, etc. Serpentine rock is also a good fertilizer ingredient.
Megalite rock
Weijing rock is a coarse-grained to coarse-grained vein like or blocky rock mass that is closely related to various deep-seated rocks in terms of genesis. It is generally flesh red, gray white, and has a coarse-grained or coarse-grained structure, ranging from acidic to alkaline veins. Often in the form of veins and produced in groups. The mineral crystals are very coarse, ranging from several centimeters to several meters, with banded structures.
marble
Marble originally refers to white limestone with black patterns produced in Dali, Yunnan Province. Its cross-section can form a natural ink landscape painting. In ancient times, marble with formed patterns was often selected to make painting screens or inlaid paintings. Later on, the name marble gradually evolved to refer to limestone with various colors and patterns used as building decoration materials. White marble is generally called White Marble, but it is also called marble for the white marble used to make statues in the West. There is a saying about the name of marble - in the past, Dali in China had the best quality marble. Named after it.
Laita Limestone
Leta limestone is a geological formation mainly distributed in Austria, Czech Republic, Hungary, and Poland. This type of limestone was formed during the Middle Miocene to Late Miocene period (approximately 16 to 7.2 million years ago). The name Laita Limestone comes from the Laita Mountains in Austria. This limestone is known for its rich fossil content, including sharks, rays, manatees, and whales.
Limestone limestone
Limestone, also known as calcareous limestone, is a sedimentary rock formed by the deposition of calcium carbonate. It is usually formed in hot springs, rivers, or lakes and is known for its porous and lightweight properties. The formation process of limestone involves mineral rich water flowing over the surface, and as the water evaporates, calcium carbonate gradually deposits, forming a layered rock structure. It is currently housed in the UAIC Museum of Minerals and Petrography.

Granite porphyry
Granite porphyry belongs to acidic rocks and is variegated; Spotted structure; Blocky structure; The main mineral composition is potassium feldspar and quartz. The mineral composition of granite porphyry is the same as that of the corresponding plutonic rock - granite, but it has a porphyritic structure, indicating that it is a shallow plutonic rock.
Feldspar sandstone
Feldspathic sandstone is a sedimentary rock mainly composed of various sand particles cemented together, with particle diameters ranging from 0.05-2mm. The sand content should be greater than 50%, and the structure is stable. It usually appears light brown or red and mainly contains silicon, calcium, clay, and iron oxide. The vast majority of sandstone is composed of quartz or feldspar.
