橄榄安粗岩组合是公认的年青岛弧三种岩石组合的一种(其余两种是拉斑玄武岩组合和钙-碱性岩组合),但是也报道:具类似化学特征的岩石产自大陆边缘。 关于橄榄安粗岩类产出的评论指出,有一组富钾的近饱和岩石与钙-碱性和碱性岩有亲缘关系,应该把它们像橄榄安粗岩组合一样单独考虑。化学特征表和平均分析数据表有助于把橄榄安粗岩组合和其他
The olivanite assemblage is recognized as one of the three arc combinations of the annual Qingdao arc (the remaining two are tholeiite combinations and calcium-alkaline rock assemblages), but it is also reported that rocks with similar chemical characteristics originate from continental margins . A commentary on the production of the Oligrods suggests that a group of potassium-rich, nearly saturated rocks have a genetic relationship with calc-alkaline and alkaline rocks and should be considered separately as the olivanite assemblage. The chemical characteristics table and the average analysis data sheet help to put olivan cohosh combination and others
