Technical Field

[0001] The utility model relates to the technical field of rock test devices, and particularly relates to a diagenesis and mineralization simulation test device. Background Technique

[0002] Diagenesis and mineralization simulation tests are of great significance in the fields of resource exploration and development, geological science research, environmental protection, and multidisciplinary intersections. Their research background is driven by both economic and social needs and also benefits from the continuous progress of science and technology. They are important experimental means for studying the formation processes of sedimentary rocks and the generation of minerals. Currently, with the progress of technology and the increasing demand for resources, the background of diagenesis and mineralization simulation tests is mainly reflected in the following aspects:

[0003] Driven by resource demand: The growth of the global population and the acceleration of the industrialization process have led to an increasing demand for mineral resources. This includes the demand for metallic minerals, non-metallic minerals, and energy minerals (such as coal, oil, and natural gas, etc.).

[0004] Deepening of geological theory research: The deepening of basic geological theory research on sedimentation, diagenesis, and mineralization has promoted the simulation and understanding of the diagenesis and mineralization processes. These studies not only help to explain the formation processes of ore deposits in geological history but may also guide modern mineral exploration and development.

[0005] Environment and sustainable development: With the improvement of environmental protection awareness, the research on the environmental impacts during the development of mineral resources has gradually received attention. Through simulation experiments, it is possible to better predict and evaluate the environmental impacts brought about by mineral development, and thus take corresponding reduction and prevention measures.

[0006] Advances in science and technology: The development of modern science and technology, especially the progress of computer simulation technology, advanced analytical instruments (such as scanning electron microscopes, X-ray diffractometers, synchrotron radiation, etc.), and experimental equipment, has made it possible to finely simulate the diagenesis and mineralization processes. This provides convenience for approximately reproducing complex geological processes in nature under laboratory conditions.

[0007] Demonstration role and experience accumulation: Through diagenesis and mineralization simulation tests, a large amount of data and experience have been accumulated, providing a scientific basis and practical guidelines for the exploration and development of mineral resources. These research results can be directly applied to actual ore deposit exploration and mining area evaluation.

[0008] In order to provide perfect test facilities for the majority of scientific research personnel, enabling them to combine theory with experiments and verify with the diagenesis and mineralization test device for demonstration, a diagenesis and mineralization simulation test device is proposed.
