The Geological History of the Townsville Area, Australia
From a Biblical Flood Perspective
Early Flood—the Ascending Phase
The oldest rocks well exposed in the Townsville district are around Charters Towers and are the remnants of a once-extensive sequence of sediments and volcanics. These were deposited rapidly and early during the global Flood (Genesis 6–8). The remains of these rocks have been called the Lolworth-Ravenswood Block. Soon after they were deposited they were crumpled (deformed) and metamorphosed (recrystallised) into schist, quartzite and gneiss.
After this, and also during the early phase of the Flood, the eastern part of Australia was dominated by geological developments in the Tasman Zone. Rocks deposited at this time are now exposed in the fold belts of eastern Australia. A large volume of material was deposited including fine silt, poorly sorted sand, beds of chemically deposited silica, black volcanic lava and fossiliferous limestone.
Tectonic movements in the earth’s crust compressed and uplifted these deposits above sea level. Some rocks were folded by the compression while others were severely deformed and disrupted. The basement areas are large and have been given different names depending on where they are exposed (figure 1). The exposed rocks were severely eroded as the water uplifted with the sediment flowed off the continent….
