In 12 Moon 11 Date to 12 At the press conference on the achievements of China’s Regional Geology Atlas and the symposium on regional geology and metallogenic settings held in Beijing, reporters learned that Chinese geologists have innovatively proposed the academic concept of oceanic plate geology. It is expected that by developing this field of oceanic plate geology, they will conduct innovative, comprehensive research into the formation and evolution of mainland China and further advance China’s regional geological theory.

　　 “ During the compilation process, we... 10 Ophiolitic mélange rocks in multiple provinces (and autonomous regions) have been surveyed and discussed, and some areas have undergone specialized studies. ” Li Tingdong, an academician of the Chinese Academy of Sciences, told a reporter from Science and Technology Daily that relatively typical accretionary complexes composed of oceanic plate stratigraphic systems have been discovered in many orogenic belts, such as the Heilongjiang Group in Heilongjiang Province and the Huashan Group in Dahongshan, Hubei Province. This has laid a solid foundation for research in oceanic plate geology. Through comprehensive studies of massive datasets and tackling major geological challenges, significant new discoveries and insights have been made in geological scientific and technological innovation, thus laying the groundwork and providing crucial support for advancing geological theory.

　　 “ China is home to extensive orogenic belts of various ages and types. Research in oceanic plate geology holds the key to unlocking many geological mysteries surrounding these orogenic belts. ” Academician Li Tingdong introduced that we have conducted research and exploration focused on the core issues of oceanic plate geology:

　　First, research on orogenic belts has been strengthened by placing greater emphasis on the study of oceanic plate stratigraphic systems. Starting with the investigation of subduction-accretion complexes, we aim to identify oceanic plate stratigraphic assemblages, including seamounts, oceanic plateaus, intra-oceanic arcs, and deep-sea environments. — Sedimentary strata formed in various tectonic settings, such as the bathyal and mesopelagic zones, reconstruct the entire evolutionary process of oceanic plates within orogenic belts—from their formation at mid-ocean ridges to their subduction into trenches.

　　Second, we conducted a study on the tectonic setting and evolution of orogenic belts based on the classification of ophiolite types. Different types of ophiolites have formed during various stages—from plate divergence to convergence—and these have now been discovered in China. 60 Multiple ophiolite belts. We emphasize the need to establish distinctive diagnostic criteria for different types of ophiolites, accurately classify ophiolite types, reconstruct the tectonic characteristics of the ocean basins represented by these ophiolite belts, and reconstitute the ocean-basin tectonic systems of orogenic belts. By examining ophiolites from the perspectives of ocean basin evolution and ocean-continent transitions, we have opened up new avenues for ophiolite research.

　　Third, we conducted research on the ocean-to-land transition process. The focus was on the trench during the ocean-to-land transformation. - The material sources of sedimentary rocks within arc systems and the formation mechanisms of island-arc magmatic rocks in subduction zones. The association of forearc basalts, boninites, adakites, niobium-rich basalts, and high-magnesium andesites represents the typical lithological assemblage marking the transition from oceanic to continental settings—the hallmark rock suite signaling the transformation of an ocean basin into a nascent continental arc—and has thus received our particular attention.
