| 中文摘要:文章汇集了中国11条地球科学断面和数十条人工地震剖面，对中国大 陆的地壳结构进行了综合研究。获得了主要成矿域的地壳分层结构模型。根据各层的厚度和 地震波速度差异，揭示出主要成矿域地壳速度结构的横向变化，勾绘出壳内低速层的分布特 征。文中还探讨了中国大陆主要成矿域岩石圈的现今活动性，以及地壳厚度、壳内低速层、 “墙式”地震剪切波垂向低速带和下地壳底部高速层(体)的分布特征以及与成矿作用的关系 。 |

| Abstract:Based on the geoscience transects and the seismic data，the authors have calculated the thickness of the crust and constructed the velocity model of some metallogenic provinces in China. It is shown that the crust becomes thinner and thinner from eastern to western in China. The velocity histogram map of the crustal structure is compiled in accord with the metallogenic provinces of China. The horizontal low velocity layer, the vertical low velocity zone and the high velocity layer in the basement of the lower crust are related to the ore_forming processes. |
