Volcanic activity is the most stunning geological activity on Earth. Many volcanic rocks have been dispersed in China since the Phanerozoic, and these volcanic rocks are related to continental crust evolution, crust-mantle interaction, and the formation of mineral resources. With the development of analytical techniques, a large number of Chinese volcanic rocks analytical data have been published in recent years. We are committed to collecting data on major and trace elements, isotopes, and chronology of Chinese volcanic rocks, which will provide us with a thorough understanding of the spatial and temporal distribution characteristic of volcanic rocks. In addition, the analysis of big data may provide us with a unique perspective to understand the crust-mantle material cycle, continental crustal evolution, and earth deep compositional architecture.
