High grade metamorphic Precambrian rocks occur in this area situated to east and southeast of Harts Range Police Station.
There is actually no formally defined "Entia valley" locality. There is a geologic dome called the Entia dome which has a "brain"-like pattern covering around 160 sq kms (see satellite map. This area is located between approximately 134.55°E and 135.25°E and 23.00°S and 23.30°S. The "valley" area immediately to the south of this is what is commonly known as "Entia valley".
It is an area well known amongst collectors for quartz crystals, especially sceptres.
The Entia Valley, or geological Entia Dome, covers much of the eastern Harts Range. Within this are a number of small historic mica mines, and gemstone deposits. Specimens from the area for various reasons are often labelled just 'Entia Valley', rather than the specific deposit, prospect or mine they came from. See Ambalindum Station main heading for access details.
