The cores are the glasses and searchlights for underground treasure. The complete preservation of the prospecting core provides valuable basic data for further green exploration, mineralization factors, geological research and other technical experiments. The libraries are equipped with combined beam shelves to make the storage of core materials standardization and management information, and equipped with touch-screen quick query systems, which integrate the storage location of the cores, image data, lithological features and other information, making the query more convenient and fast. More importantly, the preservation of these cores not only has a strong guiding role for the further exploration of Guo jiagou lead-zinc, but also is valuable for geological experts to strengthen the study of Xicheng lead-zinc ore belt.
