The Gungahlin suburb is underlain by the middle Silurian age Canberra Formation. Most of this is slaty shale and mudstone. But there are also a couple of bands of ashstone in the south and north west. The structure of the rock has been folded by anticlines and a syncline with a north east direction. The Gungahlin Fault is parallel to the folds and passes through the east of the town centre. To the south it passes through Crace, Kaleen, Bruce and Aranda where it stops at the Deakin Fault. The Gungahlin Fault is also parallel to the Winslade Fault and is no doubt connected with it. In the north east direction it passes out of the ACT northern end and ends near the Sullivans Fault.
