mafic

• Layered mafic intrusions not only represent natural laboratories for studying processes of magmatic differentiation and assimilation within the crust , but also contain extensive precious and base metal mineralization
  层状镁铁质岩体不仅是研究岩浆分异演化过程和地壳混染作用的最佳天然实验室，其中还广泛赋存重要的稀有金属和贱金属矿床。
• Mafic along with ccfip has been instrumental in introducing new technologies and providing a quality of service that is well recognized throughout the industry and has supported professional and commercial linkages domestically and internationally
  中加饲料工业项目协助“中心”推动了新技术在行业的应用，所提供服务的质量得到了行业的普遍认可。
• In contrast , mafic volcanoes , which range from small cinder cones to large shield volcanoes like north sister and belknap crater , are typically short - lived ( weeks to centuries ) and erupt less explosively than do composite volcanoes
  相反，铁镁质的火山，从小的煤渣圆堆到大的盾形火山，像北峰和贝尔克奈普坑，形成期还很短，比复合体的火山更少爆发。
• Therefore , based on the isotopic chorology , petrochemistry , geochemisty and sr , nd , pb isotope , the ph . d dissertation mainly studied some yanshanian mafic dikes , volcanic rocks and alkalic - ultramafic dikes in shandong province
  本论文主要从同位素年代学、岩石化学、地球化学和sr ? nd ? pb同位素方面对山东地区燕山期基性脉岩、火山岩和碱性超基性脉岩进行了系统研究。
• In addition , the mafic dykes of hainan island were formed in an intraplate extensional environment , similar to the mafic dykes in north guangdong and fujian coastal areas , all suggesting an extension regime tectonic in southeastern china during cretaceous
  白垩纪基性岩脉( 81 135ma )形成于板内拉张环境，与粤北、福建沿海地区的白垩纪基性岩脉共同指示了中国东南部白垩纪时期处于拉张的构造环境。
• It also conducts basic research plus concentrates on applied research projects to address specific problems that have been identified by the feed industry . in addition , mafic provides technical services , training and extension courses , information technology through its website
  技术文献资料室数据库和质量控制手段包括饲料分析与最低成本日粮配方来为行业提供各种技术服务培训和技术推广课程以及信息技术。
• The project continued to provide essential technical assistance and training to the mafic institution in support of its role as a nationally designated reference laboratory for specific analysis and training in relation to feed and food safety programs
  中加饲料工业项目将继续为农业部饲料工业中心提供必要的技术支持和培训，以支持“中心”更好地参与饲料和食品安全计划，以及作为国家认可的实验室开展有关的分析检测工作。
• Compared with jianchaling nickel sulflde deposit , jinchuan superlarge copper - nickel sulflde deposit mostly related with mafic - ultramafic complex that multiple intruded , spatially respected with old huabei block , which formed in marginal rift in middle - new proterozoic
  与煎茶岭镍矿床相比，金川超大型镍铜硫化物矿床主要与多次侵入的镁铁?超镁铁质杂岩有关，空间上与时代相对较老的华北地块关系密切，形成于中?新元古代的边缘裂谷。
• Under the cooperation of lifts and mantle fluids , the melting point of mantle peridotite fell , and then , extensive melting took place in the enriched mantle , which resulted in the appearance of abundant mafic dikes , ultramafic dikes and contemporaneous volcanic rocks in shandong province
  综合碱性超基性脉岩和已知的青山组的火山岩、基性脉岩年龄数据，认为山东地区中生代地壳拉张至少存在四次：即约80ma 、 100ma 、 120ma和140ma 。
• All of the mafic samples have age - corrected moderate enriched sr and enriched nd isotopic ratios and the felsic rocks span larger range in the initial sr and nd isotopic ratios than mafic volcanics , similar to isotopic compositions of lower crust of north china block
  在sr - nd同位素组成上，中基性火山岩为中等富集的sr和低的nd同位素比值；中酸性火山岩的sr同位素比值总体较中基性岩高且变化大，类似华北陆块下地壳岩石的同位素组成特征。
