Abstract. The reconstruction of thermal evolution in sedimentary basins is a key input for constraining geodynamic processes and geo-energy resource potential. We present a methodology to reproduce the most important transient thermal footprints accompanying basin formation: lithosphere extension and sedimentation. The forward model is extended with data assimilation to constrain models with temperature measurements. We apply the methodology to the NW part of Hungary. Realistic past- and present-day temperature predictions for the entire lithosphere are achieved, suggesting the relatively uniform, but strong attenuation of the mantle lithosphere through extension, and relatively small variations in the present-day thermal lithosphere thickness. The new temperature model allows an improved estimation of lithosphere rheology and the interpretation of mantle xenolith origins.

模拟岩石圈瞬态热过程：在西北潘诺尼亚盆地的应用

摘要。沉积盆地热演化重建是约束地球动力学过程和地能资源潜力的关键输入。我们提出了一种方法来重现伴随盆地形成的最重要的瞬态热足迹：岩石圈延伸和沉积。正演模型通过数据同化进行扩展，以用温度测量来约束模型。我们将该方法应用于匈牙利的西北部地区。对整个岩石圈的过去和现在的温度进行了现实的预测，这表明地幔岩石圈通过伸展而相对均匀但强烈的衰减，并且当今热岩石圈厚度的变化相对较小。新的温度模型可以改进岩石圈流变学的估计和地幔捕虏体起源的解释。
