Asinaturas Magnéticas E Geomórfica Do Domo De Umuarama-Pr

This paper presents an integrated study of magnetic, geologic and geomorphologic data of the Umuarama<br>geomorphic anomaly, Parana Basin. The geology is formed by cretaceous sediments (sands), basalts (Serra<br>Geral Formation) and alluvium. The geomorphic anomaly shows a radial drainage pattern but the geologic<br>surveys did not give a clear response of a structural high. The magnetic interpretation defined a structural<br>pattern with NW-SE, NE-SW and secondary E-W lineaments and the configuration of a dome structure with<br>approximated area of 10.000km2.
