Rock specimens are indispensable tools in Earth science research, they not only record the formation and evolution of the Earth, but also reveal information about ancient environmental and climate changes. These natural specimens are composed of rock layers, minerals and fossils that show the geological features of different periods of Earth's history. By studying rock samples, scientists can learn about Earth's tectonic activity, volcanic eruptions and other natural phenomena.
Rock specimens are generally divided into three categories: sedimentary, igneous, and metamorphic. Sedimentary rocks are formed mainly by the compaction of sediments, which records the sedimentary process of the paleoenvironment. Igneous rocks are formed by the cooling and solidification of molten magma, revealing the internal thermodynamic processes of the earth. Metamorphic rocks are transformed from other rocks under high temperature and pressure, reflecting the influence of crustal movement.
Rock specimens are not only of great significance to geological research, but also play an important role in mineral resource exploration and environmental protection. Through the systematic study of these specimens, scientists can better understand the evolution of the Earth, so as to provide scientific basis for sustainable development.

Rock samples are important objects of geological research, and through the analysis of rock samples, scientists can reveal the history, structure and evolution of the earth. Rock specimens are usually classified according to their composition, formation process and structural characteristics, which are mainly divided into three categories: igneous rock, sedimentary rock and metamorphic rock.
Igneous rocks are formed by the cooling and solidification of liquid magma, such as granite and basalt. They reveal the workings and tectonics of the Earth's interior; Sedimentary rocks are formed by the compaction and consolidation of sediments in water bodies, such as sandstone and limestone, which record ancient environmental and climate changes. Metamorphic rocks are the result of metamorphism of primary rocks under high temperature and pressure, such as marble and gneiss, reflecting the history of crustal movement.
Rock specimens not only provide basic data for geological research, but also play an important role in mineral exploration, soil research and ecological protection. Through the analysis of rock samples, scientists can gain insight into the evolution of the Earth and provide scientific basis for resource development and environmental protection.

A rock specimen is a rock sample that has been collected, cut and processed for classification, study and display. They are not only important objects of geological research, but also witness to the Earth's history and environmental changes. Rock specimens are generally divided into three main categories: igneous, sedimentary and metamorphic rocks, each with its own unique origin and characteristics.
Igneous rocks are formed by cooling and solidifying magma, such as granite and basalt; Sedimentary rocks, such as sandstone and limestone, are formed by sediment settling in water or air. Metamorphic rocks, such as gneiss and SLATE, are formed by physical and chemical changes of the original rocks under high temperature and pressure.
Rock specimens are of great significance in geological research, they can reveal the earth's structure, mineral resources distribution, paleoclimate change and so on. In addition, rock specimens are often used for education and popular science to help the public better understand earth science and natural phenomena. Through the observation and analysis of rocks, students and enthusiasts are able to gain a deep understanding of the evolution of the Earth and its complexity.
