确定岩石圈结构对研究其起源和进化特征,解释不同岩石圈结构对其下部地幔对流和周边板块构造运动的浅层响应有着重要的作用.本文基于1D岩石圈均衡理论,推导了一种快速求算岩石圈结构的方法,利用最新发布的CRUST1.0地壳模型,计算了全球岩石圈结构.通过与岩石圈已有研究结果的对比分析,得出如下结论:(1)海洋地区的岩石圈厚度与洋壳地质年龄呈正关系,距离洋中脊越远,地质年龄越大,对应的岩石圈就越厚;(2)大陆岩石圈结构更具复杂性,稳定的克拉通具有较厚的岩石圈根,厚度约120~220km,且厚度分布与岩石圈地质年龄有近似的正关系.除北美科迪勒拉山造山带岩石圈厚度较薄外,其余造山带具有较厚的岩石圈根;(3)同一类型岩石圈的Moho与LAB深度有一定的回归关系;不同类型的岩石圈,其回归关系不同,这可能与岩石圈形成年代、长时期所处的构造环境和地幔熔融过程等因素有关. Determining the lithosphere structure plays an important role in studying its origin and evolutionary features and explaining the shallow response of different lithospheric structures to the lower mantle convection and the tectonic movement of the surrounding plate.Based on the 1D lithosphere equilibrium theory, Based on the CRUST1.0 crustal model released recently, the global lithospheric structure was calculated and compared with the existing research results of the lithosphere, the following conclusions are drawn: (1) The lithospheric thickness And the geologic age of the oceanic crust is positive. The farther away from the mid-ocean ridge, the geologic age is, the thicker the corresponding lithosphere. (2) The continental lithosphere structure is more complex and the stable craton has a thick lithosphere The root thickness is about 120 ~ 220km, and the thickness distribution has an approximately positive relationship with lithospheric geologic age.Among the North American Cordillera orogenic belt, the other lithosphere has thicker lithospheric roots. 3) There is a certain relationship between the Moho and the depth of LAB in the same type of lithosphere. The different types of lithosphere have different regressive relationships, which may be related to the lithosphere formation age, long-term tectonic setting and mantle melting Factors related processes.
