Xingyi Guizhou ichthyosaur
Xingyi Guizhou ichthyosaur
It is a medium-sized ichthyosaur with an adult length of 2 ~ 3m. Its limbs were completely evolved into paddle-like, and it was a creature capable of pelagic swimming. Its morphology and lifestyle were similar to that of today's dolphins, but the difference was that the tail fin of dolphins extended horizontally and generated power by beating the water up and down. The tail fin of Xingyi Qianichthyosaurus was bent downward and mainly played the role of steering and steering.

Sphalerite
Sphalerite
Sphalerite: a typical sulfide mineral, the main chemical composition is ZnS, and theoretically Zn accounts for 67.01%.This sphalerite is a granular aggregate, with contact bicrystal and polycrystal.The Mohs hardness is 3.5-4, which is equivalent to the hardness of copper coins. Pure sphalerite is nearly colorless and transparent, which is very rare.This sphalerite has a magnificent color, light green to yellowish brown, grease luster to diamond luster, which is caused by the difference in the types and contents of trace elements. In particular, the greater the content of Fe element, the color of sphalerite can gradually change from colorless to light yellow to brown, or even black.When the iron content is greater than 8%, it is called iron sphalerite.In addition, sphalerite is also an important carrier of valuable elements such as cadmium (Cd), indium (In), gallium (Ga) and germanium (Ge).Therefore, because sphalerite contains important scattered elements and has dazzling diamond luster and dazzling fire color, it has gradually become a new favorite in the field of investment and collection.

Azurite+Malachite
Azurite+Malachite
Azurite is an alkaline copper carbonate mineral with the molecular formula Cu3(CO3)2(OH)2. In ancient China, it is called Shiqing, "green green", "stone green" or "green lang gan", which is an ancient jade material. The crystal is columnar, the aggregate is usually granular and earthy, and the earthy block is light blue with a dull luster. Cleavage complete or medium, easily dissolved. Closely associated with malachite, found in copper deposit oxidation zone, dark blue, glassy luster. China's azurite production is mainly in Hubei province. Malachite is a carbonate mineral containing copper, the chemical composition is Cu2(OH)2CO3, the crystal form is usually cryptocrystalline stalactite, crust, nodular aggregate. It has concentric layered and fibrous radial structure. It is green, malachite green, dark green, often striped, silky luster or glass luster, opaque. Brittle, shell-like to jagged fracture. It reacts with hydrochloric acid and is easily dissolved. Azurite is easily converted into malachite, so azurite is not as widely distributed as malachite. When produced in large quantities, it can be used as copper ore, and the powder is used to make natural blue pigments. In addition, it can also be used as a sign of finding primary copper deposits. The color of blue copper ore resembles the spots on peacock feathers, which is produced in the oxidation zone of copper deposit, iron cap and the cracks in the surrounding rock. It is generally formed slightly later than malachite, but is sometimes replaced by malachite. Due to weathering, azurite is easily transformed into malachite by reducing CO2 and increasing water content, so that malachite is false in azurite.

Fluorite
Fluorite
Also known as fluorite, its main component is (CaF₂). The specimen is green and transparent, cubic in shape, 1-3cm in length, and has a glassy luster. It is a common mineral in nature that can coexist with many other minerals. It belongs to the cubic crystal system, with bright and varied colors, brittle texture, and a Mohs hardness of 4. Some specimens can emit light when subjected to friction, heating, or ultraviolet radiation. This mineral comes from volcanic magma. During the cooling process of magma, the gas and aqueous solution separated from the magma contains fluorine. As the solution rises along the fissures, the fluoride ions in the solution combine with the calcium ions in the surrounding rocks to form calcium fluoride, which cools and crystallizes to form fluorite, existing in granite, pegmatite, syenite, and other rocks. In terms of industry, fluorite is the main source of fluorine, and it can be extracted and prepared for various fluorine compounds.

calcite
calcite
Calcite, a metamorphic rock and carbonate mineral, is the most important rock-forming mineral in the crust. Its chemical composition is CaCO₃, and it has a glassy luster and is completely transparent to translucent. In its ordinary form, it is white or colorless, but it can take on a variety of colors such as pale red, yellow, light brown, rose, purple, and more due to the presence of other metals that cause coloration. Its streak is white, its hardness is 2.704--3.0, and its specific gravity is 2.6 to 2.8. When exposed to dilute hydrochloric acid, it foams vigorously. The extremely pure and completely transparent crystal, commonly known as Iceland spar, has strong birefringence and maximum polarization light capabilities that cannot be created or replaced by humans. It is a natural crystal with a polyhedral shape.
