Geophysical acquisition

Regional gravity

The Northern Territory Geological Survey (NTGS) has commenced a program of semi-regional gravity surveys over selected areas that have unresolved geological problems and unrealised mineral potential. 

There is growing awareness in the exploration industry that semi-regional gravity surveys can assist greatly in understanding rock distribution in the mineable zone.

Territory-wide gravity

NTGS conducts major regional gravity surveys, adding the resulting observations to the Geoscience Australia National Gravity Database.  

Regions of interest can be downloaded from the Geophysical Archive Data Delivery System(GADDS).

Gravity images for the whole of the Northern Territory can be viewed on the Geophysical Image Web Server, by selecting "NT wide images", "gravity" and can also be viewed in conjunction with other geophysical images. 

The NT-wide gravity images can also be made to underlie a wealth of other geoscience information provided by NTGS via STRIKE.
