During the Early Mesozoic, concomitant with the closure of the Paleo-Tethys Ocean and the collision between the North China Block and the South China Block, the Qinling‑Dabie‑Sulu Orogenic Belt underwent intense tectono‑magmatism and produced voluminous Triassic igneous rocks.This database systematically compiles geochemical and geochronological data of Triassic igneous rocks from the Qinling‑Dabie‑Sulu Orogenic Belt, and is supported by a dedicated research platform.Users can access the database through an interactive web‑based map, which provides integrated tools for data analysis, information query and map compilation.
