摘要
景宁地区1：5万区域地质调查资料表明，该地区变质宕系实为不同时代和不同成因的产物。既存在中下元古代变质基底，相当于下元古界八都群，中元古界龙泉群及吕梁期侵入岩；也存在浅变质岩即中生代地层遭受热动力变质而成。原“鹤溪群”应予摒弃。
According to the data of 1:50O 000 regional geological surveying, the metamorphic rocksin Jingning county were the products for different times and different geneses. They werecomposed of the medium-lower Proterozoic metamophic basement, which were corresponding to lower Proterozoic Badu group, medium Proterozoic Longquang group and Lulinang ageintrusive rocks, and the epimtamorphic rocks, which were Mesozoic strata formed by themal-dynamic metamorphism. The old 'Hexi gerup' should be abandoned.
