查询词典 fractional

The SiO2 content of the dike swarms varies from 50.22% to 61.10% and they are basic-intermediate rock series, mainly basic. The Al2O3 content is generally higher than 15% and they are high aluminum basaltic rocks. The lower magnesium index (Mg#=42.77~62.28) and TiO2 content (0.97~2.41%) illuminate that they suffered magnesium-iron minerals' fractional crystallization and that they did not crystallize from original basaltic magma. The values of Na2O/K2O are all above 1, indicating lower K character. Chemically discriminated, these dike swarms are sub-alkaline rock series.

岩墙群的SiO2含量为50.22~61.10%，属于基性和中基性岩类，以基性为主；它们的A12O3含量普遍高于15%，属高铝玄武岩类；具有较低的镁指数（Mg#=42.77~62.28）及TiO2含量（0.97~2.41%），说明它们经历了镁铁质矿物的结晶分异作用，也指示它们不是由原始玄武岩浆结晶；Na2O/K2O都大于1，显示出低钾的特点；岩石化学判别，岩墙群岩石属亚碱性系列。

The analysis of lamprophyrespetrology chemistry reveals that it is a series of high potassium- potassium dike rock,it is abandunt in alkali(K2O,Na2O)and has a large reducing capacity.The diagrams of the major-element variation shows that the geochemical compositions-variations of the major oxides have vague general rules of homologous magmatic fractional-crystallization.the pearce diagram of trace elements shows it intensively enriched in LILE,intensively depleted in coherence elements(such as CrNi.et al).
