“…Consequently, denudation of the entire Erzgebirge continued throughout the whole Early Cretaceous. Pre-Late Cretaceous subaerial denudation is also indicated by the occurrence of kaolinic sapropelites south of Dresden, and deep weathering horizons in the Erzgebirge foreland (e.g., Migon and Lidmar-Bergström 2001). In the Late Cretaceous, Cenomanian breccias derived from the western Erzgebirge were deposited unconformably on the basement of the eastern Erzgebirge, indicating the presence of a welldeveloped, persistent drainage system with a steep topographic gradient from the western Erzgebirge towards Dresden in the east (Voigt 1995, and references therein).…”

To study the relative and absolute timing of post-Variscan cooling and denudation processes in the Erzgebirge of the Mid-European Variscides, eight samples for apatite fission-track (AFT) analysis were collected from a~1,300 m drill-core. The fission-track data reveal two stages of accelerated cooling through the apatite partial annealing zone (APAZ; i.e., 110€10-60 C) in the Late Jurassic-Late Cretaceous and in the late Cenozoic, respectively. Late Jurassic-Late Cretaceous cooling corresponding to denudation of 1.5-5.9 km has been related to wrench tectonics along the Elbe Zone during Triassic-Jurassic Pangea breakup. Late Cenozoic exhumation of 2.1-5.6 km, and the increase of the geothermal gradient from 17€5 C km 1 (Oligocene/ Miocene) to 25-27 C km 1 (recent) is likely connected to the formation of the Eger Graben starting from the Oligocene, as a result of the late Alpine orogenic phases.

“…Em regiões de clima temperado, as glaciações do Quaternário foram responsáveis pela retirada dos regolitos desenvolvidos sob clima tropicais mais antigos (BÜDEL, 1981;Thomas, 1994), total ou parcialmente (MIGON & LIDMAR-BERGSTRÖM, 2001). Por outro lado, em regiões tropicais, os relevos mais antigos preservados podem remontar ao Revista Brasileira de Geomorfologia, v.9, n.2, p.15-28, 2008 Martins, E. S. et al Cretáceo, uma vez que a ação das fases glaciais nestas condições é a diminuição da pluviosidade e da temperatura, mas não a ponto de formação de geleiras (BÜDEL, 1981).…”

ResumoEste trabalho apresenta o mapeamento do manto de intemperismo pelo comportamento da resitividade elétrica do Distrito Federal. O levantamento foi realizado entre 2004 e 2005, constituído de 260 sondagens elétricas verticais, que alcançam até 48 m de profundidade aparente, e de 10 estações de monitoramento mensal da resistividade elétrica para avaliação das variações sazonais. Os resultados mostraram que o comportamento da resistividade elétrica depende das características físicas do solo, das alterações de umidade relacionadas com as variações de pluviosidade e da posição na paisagem. Solos rasos apresentam um comportamento de aumento da resistividade elétrica com a profundidade, enquanto solos profundos mostram diversos padrões que se relacionam com o lençol freático, onde a resistividade elétrica é mais baixa. O comportamento da profundidade da camada mais condutiva pode ser relacionado com a superfície basal de etchplanos da região estudada.

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. This picture dif fers from pre vi ous es ti mates of de nu da tion which sug gested that only 2-2.5 km has been eroded from the ax ial part of the Karkonosze dome since the ex po sure of gran ite batholith in the Perm ian.
