Geology, mineralization styles and age of ore-hosting rocks of the Proterozoic Longbohe–Sin Quyen Fe-Cu belt: Implications for regional metallogeny

A number of Proterozoic Fe-(Cu) deposits or prospects are distributed along the Ailao Shan–Red River shear zone (ASRR) in South Yunnan, China and northern Vietnam, defining the potentially important Longbohe–Sin Quyen Fe-Cu belt. This belt was tentatively considered to be initially part of the Proterozoic Kangdian Fe-Cu province in southwestern Yangtze Block (SW China) before being southeastward displaced into the Cenozoic ASRR. However, such a...
