查询词典 Cretaceous

The Cenozoic activities are dominated in the southern segmentation,with strongly tectonic uplifting and reworking. But the northern segmentation is hosted by Cretaceous uplift?exhumation,with denudating and weakly tectonic reworking in Cenozoic time.

南段是新生代活动的主控区，以强烈地构造抬升和构造改造为主，而北段总体上受制于白垩纪的抬升-剥露，新生代以来主要表现出剥蚀和弱构造改造的特征。

As the northern boundary of the North Dabie complex unit, the motion of the Xiaotian-Mozitan fault in the Early Cretaceous can be used to understand evolution of the North Dabie complex unit during doming.

If the tectonic uplift is not considered, the relief of Dabie orogen will reach at least 3km in Late-Cretaceous. As to the value of the relief reduction factor in Dabie orogen at 90Ma, the largest value appeared in northeast region, followed consecutively by the core and southeast Tanlu fault zone, with the smalleast value appeared in northwest and southwest region. The results reflect the strong uplift difference between core and North Huaiyang flank in Dabie orogen during doming extension period. Relief in the core region and southeast Tanlu fault zone is higher than those in the peripheral regions, northwest and southwest flanks are more stable than other regions.

如果不考虑构造抬升，大别造山带在晚白垩世地形起伏至少可达3km.90Ma时大别造山带地形起伏变化率在空间上呈现如下特征：东北区块最大，热窿核部其次，东南郯庐断裂区块再次，西北、西南区块最小，反映大别造山带热窿伸展期，核部与北淮阳翼之间强烈差异隆升，核部地形和东南郯庐断裂区块起伏高于周边地区，西北、西南两个翼部比其他地区稳定。

A number of geological and mineral composition and geochemical investigations indicate that the deep geodynamics process and mantle characteristics of middle Jurassic gabbros suits from south Jiangxi province are distinguish from Cretaceous gabbros suits from coastal belt of Fijian province, the former are related to mantle upwelling and lithosphere extension, the later are related to subduction and lie on back-arc basin in tectonic environment.

对赣南车步辉长岩类的地质特征、矿物学和地球化学特征进行了研究，着重讨论它与沿海辉长岩类构造环境和源区性质的不同，研究表明它可能是中国东南部中侏罗世软流圈上涌、岩石圈伸展和地壳裂解的产物，而沿海白垩纪辉长岩类的构造环境是弧后拉张盆地；车步辉长岩类的源区可能是未受到明显俯冲组分影响的富集地幔，而沿海白垩纪辉长岩类的源区可能包含较多俯冲组分。

And when you wonder how much longer the film can go on without showing dinosaurs, T-Rex finally relents and goes back to the Cretaceous.
