Australia Research Snapshots
The pictures below give something of the flavor of field work in central Australia. This is big, broad, open country! All but one of these photos were taken in the Huckitta region, about 250 km northeast of Alice Springs, where I am currently working.
View from the Johannsen Range southwest across the Bonya Hills. Reverse fault at the base of the hill in the foreground juxtaposes Cambrian sandstone of the Mount Baldwin Formation (near foreground) against Mesoproterozoic crystalline basement (broad plain and background hills). Truck for scale.
View west from Grants Bluff. Hills on right are underlain by Oorabra Arkose, originally deposited in a Neoproterozoic rift basin that was structurally inverted by reactivation of rift-bounding normal faults during the Alice Springs orogeny.
Truck in the Bush. It's a big country! Outcrop is good in ranges, but mostly nonexistent in the plains. Field work involves a lot of cross-country driving.
A typical trip into town on the Plenty Highway, which is the main east-west highway between Alice Springs and Queensland. This is the second flat tire of the trip.
David and field assistant (my daughter Mia) after repairing the third flat tire of the trip. We only carry 2 spares, so the third flat you have to actually repair by the side of the road.
Baikal Airport, International Terminal. This is a dirt airstrip serving the homestead and aboriginal community where we stayed while I was doing field work.
Monocline at the northeast end of the Jervois Range bordering the Lucy Creek Fault, an east-down reverse fault that here parallels the base of the slope. This and other reverse faults in the region formed by reactivation of pre-existing Neoproterozoic normal faults.
Overturned folds in the Bitter Springs Formation, Ruby Gap Nature Park, about 100 km east of Alice Springs in the eastern MacDonald Ranges.
End of the field day.
