Would you have guessed that Seville Farm was once at the bottom of an ocean?
Thankfully, due to the actions of techtonic plates and volcanoes we are now nestled in a pleasant valley comfortably 300 meters above sea level.
For this reason, our geological profile comprises two very distinct levels. The rock below our soils comprise of siltstone and sandstone layed down over millions of years on the ocean floor. On top of this is overlain aprroximately 10 meters of fertile rich basalt soils. Basalt soils come from weathered volcanic rock.
The Dandenong Mountain Range is the remains of an extinct volcano last active around 200 million years ago. It consists predominatly of Devonian Dacite and Rhyodacite. It is this volcano that produced our rich fertile soils.
Devonian refers to the Devonian Period, a geologic period spanning approximately 419 and 359 million years ago and Dacite refers a type of igneous, volcanic rock. Rhyodacite refers to a type of extrusive volcanic rock.
Rocks extracted during the drilling of Irrigation Bore 1 at a depth of approximately 80 meters. These were part of solid rock and were broken and rounded by the bore drilling process.
