The fully automatic online core analysis system, as an important technical equipment in the field of modern geological research, has a wide and profound application value. This system mainly targets various types of rock cores, sediment column samples, and other research objects. With its advanced technical means, it can achieve rapid non-destructive testing of rock cores.

In terms of testing functionality, the system integrates multiple measurement subsystems. The optical linear imaging subsystem can clearly present the surface texture and internal structural characteristics of the rock core, providing intuitive image data for subsequent analysis; The color spectrum measurement subsystem can accurately determine the color parameters of rock cores, and color changes are often closely related to the sedimentary environment, which helps to infer the paleoenvironmental conditions during the sedimentary period; The magnetic susceptibility measurement subsystem can reflect the content and distribution of magnetic minerals in rock cores, which is of great significance for studying changes in ancient geomagnetic fields and sedimentary processes;The XRF chemical element detection subsystem can quickly analyze the chemical element composition in rock cores, providing key data for studying the material sources and geochemical cycles of sediments; The resistivity measurement system, P-wave velocity measurement subsystem, and gamma density measurement subsystem characterize the core from different physical property perspectives, comprehensively revealing the physical characteristics of the core.

Through these measurement methods, the fully automated online core analysis system can obtain high-resolution sedimentary records and important information such as sediment chemical parameters of core samples. Based on this data, researchers can identify climate change at orbital, suborbital, decades or even smaller scales, and obtain high-resolution climate and environmental information. This plays an irreplaceable role in deepening the understanding of the climate evolution laws and environmental change mechanisms of the Earth, and plays a crucial role in multiple research fields such as paleoceanography, paleoclimatology, and sedimentology.

At present, the fully automated online core comprehensive testing system has been widely used in international scientific research and engineering fields, including core libraries in various countries and the International Ocean Drilling Program（IODP）、 This system is widely used in many projects such as mainland drilling and natural gas hydrate drilling, fully demonstrating its important position and practical value in geological research.
