The Qinling collision orogeny was completed in the Indosinian period

after a long period of plate tectonics evolution

and the Chinese land was transformed into intracontinental deformation. The pre-existing isotope age study shows that the Indosinian period is an important metallogenic period of the Qinling

and its mineralization is controlled by tectonic evolution. The mineralization of the Indosinian in the Qinling is the beginning of the Mesozoic mineralization in eastern China. The mineralization of the Indosinian in the Qinling laid the foundation for the large-scale metallogenic explosion providing a basis for the study of the transformation of the tectonic regime after the collision and collision phases. Paying attention to the study of magmatism and mineralization in the Indosinian period of the Qinling is of great significance for understanding the metallogenic regularity of the Qinling area

understanding the dynamic process of the Qinling orogenic belt evolution

and establishing the ore-forming theoretical system.
