摘要
通过国内多个矿区实例，较系统地叙述了矿产资源开发导致的生态环境破坏和污染状况。表明矿产开发中对环境污染的途径包括河流、土壤、大气、植被、生物和水库等。最后简要介绍了国内、国外几种对采矿污染比较有效的防治措施。
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.
