THE CRUSTAL TEMPERATURE FIELD IN ROMANIA.
STEADY-STATE CONDUCTION MODEL.
(Abstract)
A steady-state conduction model of the crustal temperature field based on
the heat flow distribution and information on the structure is presented for
the Romanian territory. The lateral distribution of the temperature field is
illustrated by maps at 10, 20 and 30 km depth. Large lateral thermal variations
between tectonic units are illustrated by a map of the horizontal thermal gradient
at a depth of 30 km. A Moho temperature map is also presented. The crustal
temperature field shows a warmer crust in the Pannonian Depression and in the
Neogene volcanic area (temperatures of 3-500°C at 10 km, 5-800°C at
20 km, 8000-1000°C at 30 km depth) and a colder crust in the Transylvanian
Depression, Carpathian foredeep, Moesian Platform and East European Platform
(2-300°C, 3-400°C and 4-500°C respectively).
Key words: heat flow, temperature, steady-state conduction model, crust, Romania.
