feature of tectonically deformed coal and relation with gas outburst 构造煤特征及其与瓦斯突出危险性的关系
tectonically, the tectonic units consist of the gezu-xagquka suture zone and sangxuang-nagqu-midika slab in the surveyed area 构造方面,构造单元表现为各组下秋卡结合带和桑雄那曲麦地卡板片的构造格局;新发现达仁乡夺列蛇绿岩体。
filling sections of mesozoic-cenozoic tectonically active basins in china can generally be divided into five ordered, correlatable sequence stratigraphic units 摘要中国中、新生代构造相对活动的断陷或陆内前陆盆地充填序列一般可划分出5个级别具有地层对比意义的层序地层单元。
these studies, therefore, suggest that the songsugou peridotite is not a tectonic massif of the upper mantle but a ultramafic magmatic rock body crystallized in deep crust and tectonically emplaced in the upper crust 从而证明了松树沟橄榄岩体并不是上地幔岩石的残片,而是由岩浆在深部地壳环境下结晶而成并以固态构造侵位于地壳的上部。
comprehensive analysis by combination of basin tectonism during basin formation and evolution with the basin filling and reforming is the key to reveal the configuration of depositional systems and the source, reservoir and seal in the inland tectonically active basins 摘要结合盆地形成演化过程中各种构造作用与盆地沉积充填和改造过程的成因分析,是揭示内陆构造活动盆地沉积体系域时空配置和生储盖发育分布的重要基础。
