Hanson Whiterock Quarry
The quarry lies in the Stoneyfell Quartzite Group, which is in turn part of the Adelaide Geosyncline. It is believed, to have formed during the late Proterozoic thru to the end of the Cambrian (approx 900-500 million years ago).
The quarry itself is well known for its large clear crystals of quartz, showing many different forms, from single crystals thru to multiple crystal groups. It is especially well known for its spectacular ‘Japan Law’ twinned specimens. It is also known for producing some of the largest 'totally clear' crystals in Australia.
The South Australian Museum has dedicated an entire display case to the specimens of White Rock Quarry.
All access and collecting is now prohibited; mainly because of people sneaking into the quarry to collect without permission.
The quarry commenced operations circa 1946 and provides aggregate material form the construction industry.
Heidelberg Materials Pty Ltd (formerly known as Hanson Construction) operates the quarry (since 2007).
The quarry site comprises some 137 hectares.
Located 10km east of Adelaide.
