Abstract: In this paper according to the data of Asian continental 1白1? mean gravity field of Bouguer anomaly and a monolayer, homogenous, calculative crustal model, the total 10456 gravity data belonging to 131 gravity profiles have been calculated for determining the depth of Moho discontinuity. Obtained from this has been an outline map showing the distribution of Asian continental crustal thickness. Based on these results gained, the features of distribution of the crustal thickness and outline of crustal structure under the Asian continent have been analyzed and studied. Finally, this paper advances the principal characteristics of the Asian continental crust. There exist four vast areas of relatively minor variations in the crustal thickness, namely, northern, eastern southern and central areas of Asian crust; three great comprehensive steep (progressive) variational zones of crustal thickness, i. e. Pamir-Altai-Trans-Khingan complex steep variational zone, Trans-Khingan and Da Hinggan-Taihang-Wuling-Miaoling-Hengduan mountains progressively variational zone, and Zagros-Pamir-Himalayas steep variational zone; two complex convergent "node" of steep variational zones of crustal thickness, Pamirs "node" and Hengduan mountains "node"; and one Qinghai-Xizang crustal block with great thickness.

摘要： 应用亚洲大陆地区的1°×1°平均布格重力场的数据,选择了均质单层地壳模型,对131条重力剖面的10456个重力点计算确定其莫霍界面深度,得到了亚洲大陆部分的地壳厚度分布轮廓图。 并对亚洲大陆的地壳构造轮廓作了分析与探讨,指出了四点构造特征。
