含豆荚状铬铁矿蛇绿岩与非含矿蛇绿岩

Two Types Ophiolite:One Associated with Lenticular Chromite and the Other without

笔者以蛇绿岩中铬铁矿的含矿性为依据,将蛇绿岩分为含豆荚状铬铁矿蛇绿岩和不含豆荚状铬铁矿蛇绿岩。并根据国内外蛇绿岩套的资料,总结了含矿蛇绿岩与非含矿蛇绿岩的差异,还以伏川蛇绿岩套和赣东北蛇绿岩套为例进行了说明。

On the basis of the ore potentiality of chromite associated with ophiolite,the author tried to classfythe ophiolites into two kinds one bearing lenticular chromite and the other bearing none.Consulted anumber of relevant references:oh ophiolites both at home and abroad the difference of these two kindsof ophiolites suites are summed up in this paper.Two examples of ophiolite suites are cited for illus-tration.
