| Abstract: | According to the definition given by Mr.Penrose at an international ophiolite special topic meeting in 1972,through preliminary field investigation,in chrominm-bearing,nickel-bearing mafic and ultramafic complexes in the northern Jilin orogenic belt,the typical ophiolite which has complete pseudosequence and is similar to Cyprus-type was not found.The composional characteristics are apparently different,even with an important difference.Therefore,it should not be namde as ophiolite temporarrily,they may separately belong to similar Yidun-type ,differentiation-type,mafic-ultramafic complexes formed in the tectonic developing stages. |
