3.Geochemical data indicate that Yajiangqiao trondhjemite, Huatan trondhjemite and Mopanshan granite, considered as component parts of Kangding complex formed in Late Archean or Palaeoproterozoic, are similar to TTG in such aspects as low Mg~#, Na-2O>K-2O, strong fractionationed REE, no or slightly negative Eu anomaly, low Yb-N, Cr, Ni, V, Nb, Ta, Ti, high Ba, and changeable Sr.
4.S. Wu et S.C. Chen,from which it can be easily distinguished by having a pseudobulb 1-1.5 cm long,articulated leaves,incurved-tipped lip and much longer column,and lacking an elongated rhizome underground.
5.The sandstones exposed at Jin Yah Miao, Dan xia mountain show lar- gescale tabular cross bedding with over 3m-thick cosets and 8 to 10 cm- thick sets the set has dip angle of 30-35°and somewhat converges dowornward and shows normal grading.
