Subsurface temperature model of the Hungarian part of the Pannonian Basin

摘要: Abstract Hungary is one of the most suitable countries in Europe for geothermal development, as a result large amounts Miocene extension and associated thermal attenuation lithosphere. For exploration, it crucial to have an insight into subsurface temperature distribution. A new model presented extending from surface down lithosphere-asthenosphere boundary (LAB) based on stochastic modeling workflow. The solves heat equation steady-state, assuming conduction main transfer mechanism. At top base, we adopt constant basal flow condition. calibration model, measurements were collected Geothermal Database Hungary. built up layered structure, where each layer has its own properties. prior properties condition are updated through ensemble smoother with multiple data assimilation technique. shows misfit observed temperatures, which explained fundamentally by transient effects non-conductive transfer. Other misfits can be attributed a-priori assumptions properties, conditions, uncertainty geometry. models considerably improve showing better fit measured records. capable reproduce effect lithospheric sedimentary infill Pannonian Basin. Results indicate that hottest areas below 3 km linked basement highs surrounded deep sub-basins Great Hungarian Plain. Our provide indication potential sites future EGS serve input resource assessment.
