Primary tin deposits usually contain little or no copper due to the distinct geochemistry of Sn and Cu. However, examples copper-rich in many provinces around world are also well known. The genesis remains controversial. Maodeng Sn-Cu polymetallic, a typical Cu-rich deposit southern Great Xing’an Range (SGXR) Northeast China, offers an excellent opportunity reveal coupled copper-tin deposits. o...

The genesis of deeply buried deposits in the Duobaoshan ore district, largest porphyry-related Cu-Mo-Au field northeastern China, is not well understood and their exploration lacking because fine velocity structure this region comprehensively understood. Herein, first-arrival seismic travel times were picked along a deep reflection profile inverted using tomographic method to obtain detailed up...

The Casino Cu–Au–Mo deposit is one of the largest and highest-grade porphyries its kind in Canada, residing an unglaciated region west-central Yukon. A batch 22 stream water samples eight groundwater were collected proximal to for purpose identifying most diagnostic trace element isotopic pathfinders associated with hydrothermal mineralization, as well establishing natural hydrogeochemical base...
