... the Late Cretaceous ( Xu et al., 2012 ). The Meso-Neo Proterozoic metamorphic basement, termed the Gaoligongshan Group, is considered as the oldest geological unit in the Tengchong terrane, yielding zircon U-Pb ages of 1053–635 Ma and 490–470 Ma, according to Song et al. (2010) and is mainly composed...

In the BASH system, the experiments were classified into two groups according to the mineral products. One group is shown in Figure 2 , i.e ., the images of experiment...

... ). In this case, the Tengchong Block should also be proximal to northern Australia ( Xie et al., 2016 ). However, recent studies demonstrate that the Carboniferous Menghong Group and the Gaoligongshan Complex in the Tengchong Block do not possess a marked age peak of ca. 1170 Ma but rather two dominant age...

... ). Doblas (1998) divided slickensides, steps and mirror planes into 11 types to further identify faults. Cashman and Ellis (1994) analysed multiple groups of slickensides and inverted the stress field during the development of a fault in a study area. Nevitt et al. (2014) investigated steps along...

Like most arc-type magmatic sulfide deposits worldwide, the platinum group element (PGE) tenors of the Daxueshan deposit are extremely low, indicating a severe PGE depletion of the parental magma due to previous sulfide segregation at depth...
