华北克拉通中东部岩石圈减薄研究已经成为近年固体地球科学研究的热点,同时该区域也是中国强震的多发区.在华北及邻近地区已完成了二维人工地震宽角反射/折射探测(简称DSS剖面探测)剖面42条,文章收集了这些二维探测剖面的研究成果,在对二维剖面速度结构和界面结构进行网格化处理的基础上,采用克里金(Kriging)插值方法构建了华北克拉通中东部地壳三维速度结构模型HBCrust1.0.采用走时拟合的办法对模型进行了检验,结果表明,用HBCrust1.0地壳模型计算得到的初至波走时与实际台站观测到的初至波走时之间拟合良好.研究结果表明,上地壳是主要的孕震层,C界面(上、下地壳分界面)附近区域是地壳内部的脆韧转换带.唐山地震震源区下方Moho面深度有明显的变化,其低速结构一直延续到下地壳,推断唐山地震的应力积累与地幔物质运移和变形密切相关.克拉通东部华北盆地中心区域的下地壳平均速度明显要高于周围地区,可能是地幔岩浆长期底侵作用的结果. The research on lithospheric thinning in the middle and eastern part of North China Craton has become a hot spot in solid geosciences research in recent years and is also a frequent area with strong earthquakes in China. 2D seismic reflection / refraction detection of artificial earthquakes has been completed in North China and adjacent areas Referred to as DSS profile detection) section 42, the article collected the research results of these two-dimensional detection section, based on the two-dimensional section velocity structure and interface structure of the grid based on the use of Kriging (Kriging) interpolation method to build The crustal three-dimensional velocity structure model in the middle and eastern part of North China Craton (HBCrust1.0) has been tested by using the time-of-flight fitting method. The results show that the first-arrival wave travel time calculated by HBCrust1.0 crustal model The results show that the upper crust is the main seismogenic layer, and the area near the C interface (upper and lower crust interfaces) is a brittle-ductile transition zone within the crust. Surface depth has obvious changes, its low-speed structure has been extended to the lower crust, inferred Tangshan earthquake stress accumulation and the migration and deformation of the mantle material is closely related to the craton The average speed of the central region of the lower crust of North China Basin is significantly higher than the surrounding area, it may be the result of a long underplating of mantle magma.
