Understanding the 3D structure and delineating the locations and variations of the intrusions and ore-controlling strata in the study area are essential for selecting deep mineral targets.

... al. 2019 ). The Middle-Lower Yangtze River Valley Metallogenic Belt (MLYRB), Eastern China, is one of the most important mining regions in China and is characterized by abundant large strat-abound deposits (e.g., the Dongguashan Cu-Au deposit and the Xinqiao Cu-Fe-Au deposit; Mao et al. 2011...

In addition, the Os i ( Fig. 2E ) and trace-element abundances ( Figs. 3A and 3B ) of py2 are distinct from py1; hence, a recrystallization origin of py1 from py2 is unlikely. Further, the colloform pyrite is composed of fine...
