The MIRE involved episodic rift-sag sequences, throughout its history, and all of the known deposits form in sag phases after rift events. These events may have induced dilatancy in the rocks of the basin and thus triggered basinal fluid migration events. Hydrocarbons may have behaved in similar ways, and the trapping mechanism has much to do with this fact.
Research is in progress.
The GITS works like this. First work out the basement rift geometry. To do this we used classic inversion geometries that produced many of the folds in the folded sediment layers. These allowed us to predict the location of hidden basin-forming structures, some of which we were later able to see in the geophysics. The stratabound base metal GITS thus does not require any great degree of sophistication to allow its application.
