The Consuelo Tableland to the north of Carnarvon Gorge would have been one of the first areas of land to emerge in Queensland as the waters of Noah’s Flood were receding from Australia. A rough calculation shows it would have been at least 224 days after the Flood began before the tableland emerged. The receding floodwaters carved the remarkable landscape around the tableland, including Carnarvon Gorge, when they drained from the land as the tableland emerged.

 

One prominent feature of the Consuelo Tableland is that it is capped by flows of basalt lava, which accumulated to as much as 300 metres thick in places. This basalt initially covered a much larger geographical area, but has been extensively eroded until, in many places, only remnants remain.

The above geological map illustrates these features. It shows portion of the geology of the Consuelo Tableland and surrounds, just north of Carnarvon Gorge.1 The basalt cap is coloured pink (and labelled Tb for Tertiary basalt). The figure illustrates the degree to which erosion has removed the basalt cap and cut into the underlying sandstone strata, which are coloured blue.

The Flood scenario outlined above suggests that the basalt flows were erupted while the landscape was under water, after considerable erosion (mainly in wide sheets) had already occurred. Is there any indication in the geological literature that the basalt erupted underwater?

When we check the geological reports for the area we see that the basalt has been interpreted as being deposited in a terrestrial environment.2,3,4,5 One report describes the basalt as being “extruded subaerially”6 while another describes it as being “submarine”.5 Many of the basalt flows have been described as “deeply weathered”,which means they have been chemically altered to produce a soil-like friable layer on their surface….
