| Digital Magmatic Rocks Reveal Continental Assembly, Crustal Growth, Compositional Architecture, and Their Control on Metallogenesis |
| As magmatic rocks represent one of most significant geological records on Earth, digital magmatic rocks are an important component of the digital Earth. This study reviews the progress of research in this field, including the construction of a global magmatic rock database and its applications. The development of the first domestic magmatic rock database and research platform has achieved core data and platform functions that surpass some aspects of existing international databases. Based on these data, a series of digital maps of global, Asian, and deep-time magmatic rocks were compiled and published. Notably, the following significant enhancements have been made: 1) A spatiotemporal evolution framework for Asian granites has been established, proposing three modes (straight, curved rotation, and scissor-like) and five stages of the Asian continent assembly. 2) By comparing isotopic mapping of eight typical orogenic belts worldwide, the deep material architecture characteristics of different types of orogenic belts have been identified, revealing significant crustal growth during the Phanerozoic and enriching the theory of crustal growth. 3) The deep material architecture and its constraints on mineralization have been quantitatively characterized, a framework for a deep material exploration method system has been developed, and new concepts of orogenic belt classification and material orogenic belts have been proposed. These findings contribute to a deeper understanding of orogenic belts. |
