Abstract

This paper presents a finite‐differences 3D numerical model that simulates the gravity and thermal structure of the Corsica‐Sardinia Block (CSB), an apparently stable lithospheric domain characterized by cryptic tectonic activity. In the experiments, we change the density and heat production rate of the model crust within a range of geologically realistic values to fit the measured Bouguer gravity anomaly and surface heat flow pattern. The discrepancy between the observed geophysical structure and the outcomes of numerical modelling are discussed in relation to the composition of the CSB crust and finally recast in the geodynamic framework of the western Mediterranean region.
科西嘉-撒丁岛区块的重力场和地热结构
本文介绍了一个有限差分三维数值模型,该模型模拟了科西嘉-撒丁岛区块(Corsica-Sardinia Block,CSB)的重力和热结构。在实验中,我们在一定的地质现实值范围内改变了模型地壳的密度和产热率,以适应测得的布格尔重力异常和地表热流模式。观察到的地球物理结构与数值模拟结果之间的差异与 CSB 地壳的组成有关,并最终在地中海西部地区的地球动力学框架内进行了讨论。
