Photogeological and geophysical interpretations on ELs 1386, 1388, 1389, 1463 & 1804, Tennant Creek.

Abstract

Besides the known mineral occurrence at Ivanhoe and the Queen of Sheba no magnetic anomalies of the type associated with the Tennant Creek mineralisation are present. Lower amplitude anomalies may however be important if the concept of stratiform mineralisation is correct. Five potential targets have been selected. There are no major uranium anomalies recorded and the selected anomalies are of a very low amplitude. Three potential target areas have been selected which warrant further investigation. The volcanic horizons and parts of the granites indicate higher uranium backgrounds than the other units and may be potential sources of uranium. A number of major faults have been interpreted from the geophysical data. The predominant trends are NNW-SSE, WNW to NW and ENE to NE.
