The Australian plate is currently going in a very northward course and during the time of the main volcanic action, the Mount Gambier area moved over a hotspot known as the East-Australian hotspot.
Mount Gambier is rich in caves a result of the location’s distinctive geological historical past. It’s Found around the Limestone Coast, a region characterized by porous limestone rock. With time, rainwater’s sluggish and continuous dissolution of this limestone has developed a lot of underground caves and sinkholes.
The reason for the blue seasonal transform just isn't perfectly comprehended. The top idea holds that when hotter climate provides the upper levels in the lake higher than 20° Celcius (sixty eight° Fahrenheit), the solubility of calcium carbonate inside the h2o decreases. The calcium carbonate precipitates out in the water and varieties micro-crystals, which scatter blue light. Due to the fact A lot of your neighborhood bedrock is limestone (compressed calcium carbonate), there is an sufficient source of calcium carbonate to dissolve in to the h2o.
Scientists have solved an extended-standing thriller bordering Australia's only Lively volcanic area. The volcanism springs from a unique interaction involving the continent's motion north and native variations in its thickness. Share:
"If we look at [These crystals] down the microscope, we can get started to be familiar with all the historical past of that crystal and realize its pathway from deep within the earth to the area.
Dive deep beneath the surface and explore an enchanting environment crammed with exclusive rock formations, lively marine lifestyle, and hidden treasures. The thrill of swimming as a result of dim caves and exploring new passageways is as opposed to anything else.

Situated in the city’s centre, the Cave Gardens is actually a sinkhole reworked right into a garden, much like the Umpherston Sinkhole. A rose yard was included in the late 19th century, and platforms throughout the sinkhole present excellent views in the gardens.

Situated just a quick push in the famed Kilsby’s Sinkhole, The Sisters include two nearly intersecting sinkholes divided by a dry limestone saddle. This saddle, around fifteen meters vast and three meters substantial, distinguishes the northern in the southern gap.
They say the rocks could offer information about exactly how much warning time there is likely to be in advance of an eruption
The final from the volcanic action happened forming the maar complicated that is definitely seen nowadays. Groundwater existing within the limestone aquifer percolated in the Earth and arrived into contact with the underlying magma within the Earth’s mantle. The interaction of drinking water and incredibly hot magma created steam and a big magnitude of tension was built up generating larger sized vents and fractures. A sizable eruption was developed that blew aside the overlying basalt layer and the limestone.
These unbelievable formations develop an otherworldly experience for divers who will discover the concealed depths beneath the surface.
This 75-metre (246 ft) deep lake accommodates An array of abnormal aquatic flora and fauna, in particular fields of huge stromatolites. There are lots of other craters in the city together with Valley Lake along with the Leg of Mutton River.
