Genesis of the 1.76Ga Zhaiwa Mo–Cu and its link with the Xiong’er volcanics in the North China Craton: Implications for accretionary growth along the margin of the Columbia supercontinent

The East Qinling molybdenum belt, hosting numerous Mesozoic magmatic-hydrothermal Mo deposits, is one of the largest molybdenum provinces in the world. The recently discovered Zhaiwa Mo–Cu deposit, Luoning County, Henan Province, occurs within the Xiong’er Terrane of the East Qinling orogenic belt. The Mo–Cu mineralization is associated with widespread stockworks or veinlets occurring within altered amphibolite. Here we investigate the...
