鬣刺结构

野外地质调查和室内岩石学研究表明，大兴安岭北段吉峰林场一带变质超基性岩为具有典型鬣刺结构的科马提岩。

Field geological survey and geochemistry indicate that the metamorphic ultrabasic rock in Jifeng area of the north Da Hinggan Ling Mountains is komatiite with spinifex texture .

与国外太古代绿岩带科马提岩对比，岩石化学成分、分带性、特有的鬣刺结构及区域变质特征、含矿性等方面亟相似。

The komatiite in this area is very similar to those in Archean greenstone belts abroad with respect ot the petrochemical composition , zoning , special spinifex texture , characteristics of regional metamorphism and ore potentiality .
