阳原 meaning in English
yangyuan
Examples
- The basal boundary of the nihewan formation at the tai ' ergou section of yangyuan , hebei province
河北阳原台儿沟剖面泥河湾组底界的确定 - The xenoliths in the yangyuan , including iherzolite and harzburgite , represent the direct samples from the upper mantle beneath western north china craton
阳原幔源包体包括二辉橄榄岩和方辉橄榄岩，是华北西部上地幔的直接样品。 - The early tertiary alkali basalts from yangyuan which contain abundant mantle xenoliths exhibit very homogeneous sr - nd isotopes with snd = 5 . 5 . their pb isotopes are similar to those of the depleted mantle ( dm ) and their trace element characteristics resemble those of oceanic island basalts ( oib )
含幔源包体的阳原早第三纪碱性玄武岩具有均一的sr - nd同位素组成( nd 5 . 5 ) ，其pb同位素组成与亏损地幔( dm )相似。 - Major , trace element composition and sr - nd - pb isotopes of the cenozoic basalts from yangyuan ( hebei province ) and datong ( shanxi province ) , which are located to west of the daxinanling - taihanshan gravity lineament , as well as mineral chemistry , major and trace element composition and sr - nd isotopes of mantle xenoliths from yangyuan are reported in this thesis
本文报道了大兴安岭-太行山重力梯度带以西河北阳原和山西大同新生代玄武岩的元素和sr - nd - pb同位素地球化学及阳原幔源包体的矿物化学、元素和sr - nd同位素地球化学，据此对华北克拉通西部上地幔的性质和过程进行了初步讨论。
