Influence of major fault zones on 3-D coupled fluid and heat transport for the Brandenburg region (NE German Basin)

Abstract.To quantify the influence of major fault zones on the groundwater and thermal field, 3-D finiteelement simulations are carried out. Two fault zones -the Gardelegen and Lausitz escarpments -have been integrated into an existing 3-D structure of the Brandenburg region in northeastern Germany. Different geological scenarios in terms of modelled fault permeability have been considered, of which two end-member models are discussed in detail. In addition, results from these end-member simulations are compared to a reference case in which no faults are considered.The study provides interesting results with respect to the interaction between faults and surrounding sediments and how it affects the regional groundwater circulation system and thermal field.Impermeable fault zones seem to induce no remarkable effects on the temperature distribution; that is, the thermal field is similar to the no-fault model. In addition, tight faults have only a local impact on the fluid circulation within a domain of limited spatial extent centred on the fault zone. Fluid flow from the surrounding aquifers is deviated in close proximity of the fault zones acting as hydraulic barriers that prevent lateral fluid inflow into the fault zones.Permeable fault zones induce a pronounced thermal signature with alternating up-and downward flow along the same structures. Fluid flow along the plane of the faults is principally driven by existing hydraulic head gradients, but may be further enhanced by buoyancy forces. Within recharge domains, fluid advection induces a strong cooling in the fault zones. Discharge domains at shallow depth levels (∼ < −450 m) are instead characterized by the presence of rising warm fluids, which results in a local increase of temperatures which are up to 15• C higher than in the no-fault case. This study is the first attempt to investigate the impact of major fault zones on a 3-D basin scale for the coupled fluid and heat transport in the Brandenburg region. The approach enables a quantification of mechanisms controlling fluid flow and temperature distribution both within surrounding sediments and fault zones as well as how they dynamically interact. Therefore, the results from the modelling provide useful indications for geothermal energy exploration.

Ero sional his tory of the Karkonosze Gran ite Mas sif -con straints from ad ja cent sed i men tary bas ins and thermochronologyThe long-term ero sional his tory of the Karkonosze Gran ite Mas sif is re vised and re con structed us ing dif fer ent sources of in for ma tion, includ ing the sed i men tary re cord of ad ja cent bas ins, pre vi ously pub lished low-tem per a ture thermochronological data and geomorphic features. Al though the ev i dence is still in com plete, this work has iden ti fied a num ber of in ter vals, of un equal du ra tion, char ac ter ized by dif fer ent de nu da tion re gimes and rates. Sev eral ma jor phases of rapid ex hu ma tion are in ferred -in the Perm ian and the Early Tri as sic as seen in the sed i men tary re cord, and in the Late Cre ta ceous as shown by both the thermochronological and sed i men tary re cords. Neotectonic up lift of the Karkonosze Mts. in the late Ce no zoic is not re corded in the thermochronological re cord and there is no ev i dence of any ac cel er ated de nu da tion close to the mas sif. Ap a tite fis sion track data show that >~3.6 km of rock must have been eroded since the Turonian, while the re sults of zir con (U-Th)/He anal y sis sug gest that in places ero sion of >~6 km of rock must have taken place.

It formed dur ing Paleogene times pre sum ably due to flu vial and sub ma rine ero sion, con cen trated along a lo cal pre-Late Badenian graben sys tem. All mem bers of the foredeep's Badenian-Sarmatian sed i men tary fill at tain dis tinctly greater val ues in side the palaeovalley than on top of el e vated pla teaux on palaeovalley shoul ders. The fill com prises the Early to Late Badenian sub-evaporite Skawina For ma tion, the lat er ally equiv a lent Late Badenian evaporite Krzyżanowice and Wieliczka for ma tions and the su pra-evaporite Late Badenian to Early Sarmatian Machów For ma tion. Over the pla teaux and in the high est palaeovalley seg ment, the evaporites are de vel oped in the sulphate fa cies Krzyżanowice For ma tion, whereas in the lower palaeovalley seg ments chlo ride-sul phate fa cies evaporites of the Wieliczka For ma tion oc cur. The rock salt-bear ing rocks are in volved in thrust ing and fold ing at the Carpathian orogenic front, which helps to as sess the lat eral ex tent of the Wieliczka For ma tion in seis mic re cords. The deep palaeotopographic po si tion of the evaporites in side the palaeovalley, com bined with their lithological and sed i men tary fea tures, point to their forma tion via sub aque ous grav ity flow-driven redeposition of orig i nally shal low-wa ter evaporites, pref er en tially ha lite-bear ing, pre sum ably com bined with pre cip i ta tion from sul phate and chlo ride brines at the palaeovalley floor.
