汉诺坝玄武岩分布在河北省北部崇礼至尚义一带,面积达1700平方公里。晚第三纪大麻坪玄武岩是其中的一部分,它以富含大个超镁铁质岩包体而著名。我们的目的是用稀土元素数据(REE由仪器中子活化分析测定)来研究它们的成因。其岩相学、地球化学及矿物学的详细研究将另行发表。
Hannuoba basalts are distributed in the northern part of Hebei Province, Chongli to Shangyi, an area of 1,700 square kilometers. The late Tertiary Maumpang basalts were part of the group, famous for its rich mafic ultramafic rocks. Our goal is to investigate their genesis using REE data (REE by instrumental neutron activation analysis). A detailed study of its petrography, geochemistry and mineralogy will be published separately.
