White Cliffs of Dover
The White Cliffs of Dover, located on the coast of Dover in Kent on the south-east coast of England, facing the coast of France, is one of the UK's most iconic natural landmarks. The cliff's striking white appearance is due to its pure chalk (Chalk) composition, formed millions of years ago by the compression of skeletal remains of tiny marine organisms from the Cretaceous period. The cliff face can be up to 110 meters (350 feet) high and stretches for about 13 kilometers (8 miles) along the coastline. For travellers across the English Channel, especially in wartime, the White Cliffs of Dover have long been a symbol of Britain, representing home, hope and peace.
United States Arizona Red Cliff National Preserve

Ruby is a very hard and durable gemstone, with a hardness of on the Mohs scale, second only to diamonds. The color of ruby ranges from pink to deep red, and the intensity of the color depends on the amount of chromium in the crystal structure. Ruby usually exhibits a hexagonal crystal structure, and the crystal is usually prismatic with a flat base end face. Due to its beautiful color and high hardness, rubies are widely used in jewelry, such as rings, necklaces and bracelets.
Quartz crystals of hydrothermal deposits
Quartz crystals from hydrothermal deposits are very important mineral specimens in geology. Quartz is a common mineral with the chemical composition of silicon dioxide (SiO₂), which is widely found in the earth's crust. In hydrothermal deposits, quartz crystals are usually precipitated from silicon-rich hydrothermal solutions under high temperature and high pressure conditions. These crystals can exhibit complex growth textures, such as oscillatory banded textures, mosaic textures, and concentric ring-banded textures. Quartz crystals often contain fluid inclusions, which can provide important information about the formation conditions of the deposit, such as temperature, pressure and fluid composition.
Polished Amethyst
Polished amethyst is a popular gemstone specimen. Amethyst is a purple variety of quartz that ranges in color from light purple to dark purple and is determined primarily by the presence of iron and other trace elements. Quartz is a common mineral with the chemical composition of silicon dioxide (SiO₂), which is widely found in the earth's crust. Polished amethyst and quartz are often used in jewelry and ornaments because their luster and beautiful color make them very attractive.

Gurasada agate is a beautiful mineral specimen from the Gurasada region of Romania. Agate is a ribbon-shaped chalcedony (a subspecies of quartz), the strips of which can be parallel or concentric. This agate is usually embedded in diabase, a fine to medium-grained intrusive igneous rock that is usually dark gray to black in color. This polished agate specimen measures 9 x 8.5 x 8cm and has a chemical composition of silicon dioxide (SiO₂).
Peruvian cubic pyrite
Peruvian pyrite is mainly produced in Peru's famous Huanzala mine. This pyrite is known for its brass-colored luster and distinctive striated surface. Pyrite derives its name from the Greek word pyr, which means fire, because it produces sparks when it collides with other minerals or metals. This pyrite is usually in the shape of a cube, with a highly glossy surface, giving a mirror-like visual effect. Not only are they of great value in mineralogical research, they are also favored by collectors and mineral lovers for their beautiful appearance.
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.
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.
clinopyroxene
Pyroxene (pyroxene,augite) is a common single-chain silicate rock-forming mineral, which widely exists in igneous rocks and metamorphic rocks. The main framework is composed of silicon-oxygen molecular chains. The crystal structure is monoclinic or orthorhombic, and the main component is XY(Si,Al)2O6, where X represents calcium, sodium, magnesium and divalent iron, there are also some kinds of ions such as zinc, manganese and lithium. Y represents smaller ions such as chlorine, aluminum, trivalent iron, vanadium, scandium, etc.
The volcanic bomb on Tenerife Island
The volcanic bomb from Tenerife is a type of igneous rock formed during volcanic eruptions. These volcanic bombs are formed by the cooling and solidification of molten magma in the air, usually with unique shapes and textures. During a volcanic eruption, molten magma ejected from the volcano is formed by flying and cooling in the air. These rock blocks undergo rapid cooling and solidification in the air before finally falling to the ground. Volcanic bombs come in various shapes and sizes, usually presenting streamlined, spindle shaped, or irregular shapes.
Uranium bearing igneous rock
Sphalerite
There are various colors of sphalerite, including white, gray, yellow (yellow patterned stone), blue, green, pink, and brown, while the stripes are white. The zinc in the composition is sometimes replaced by iron or manganese, and occasionally by small amounts of magnesium, calcium, cadmium, copper, cobalt, or lead. Similar to most carbonate minerals, it dissolves in hydrochloric acid and produces bubbles. In the calcite group, sphalerite belongs to a type with high hardness and specific gravity. In nature, zinc containing minerals are mostly sphalerite, and the production of sphalerite is relatively much lower. In addition to extracting zinc, it can also be used as semi transparent green or green blue gemstone jewelry.
C ă limani sulfur
The large chunks of sulfur from the C ă limani open-pit mine in Romania are a mineral found in the C ă limani volcanic mountain range. This open-pit mine is located in Suceava County, Romania. It was once a large sulfur mine that began in 1969 and was closed from 1992 to 1995. The chemical formula of sulfur is S, and pure sulfur appears bright yellow. Pure sulfur is usually bright yellow, but its color may change due to impurities such as clay and selenium impurities, which can cause it to appear red, green, brown, or gray. The C ă limani open-pit mine is a volcanic sulfur deposit.
