Opalology is the Geology of OpalThe Geology of Opal Country

All the original finds throughout Australia were ‘floaters’ – pieces of opal, which had been eroded out from the horizontal opal levels within the desert sandstones. Weathered out from the high grounds on to the slopes and flats by wind, rain and ground movements over eons of time. Faults are essential to the process of opalisation as they provided channels for the transport of water as well as barriers against water loss after mineralisation commenced.

Opal Deposits Around the Globe

Opal Planet

Opals form on all continents of the globe and have been sought after worldwide since ancient times.  

Whereas, the Australian opal fields are founded upon sedimentary geology, opals found outside of Australia are predominantly volcanic in origin.

Sea Plankton share the same chemical composition as common opal. Consequently, opal is being deposited on the deep ocean floor where dead Plankton sink and collect everyday. 

Eureka, Shearers Strikes & Opal Rushes

on . Posted in Opal Mining

Blood Diamonds & Battlers

The United Nations General Assembly recognized that conflict diamonds are a crucial factor in prolonging brutal wars in parts of Africa. Fortunately Australia is and always has been a stable country with strong labour rights and a uniquely egalitarian ethic.

During the Great Shearers' Strikes in the 1890s, five hundred shearers were camped just south of Winton in outback Queensland as the town was placed under marshal law. This was not only the beginning of the foundation of the Australian Labor Party, but an opportune time when disaffected men without work were willing to chance their luck; It is by no coincidence that Opalton, 100 kilometers further south, developed into a township of 600 (nearly twice Winton's population) during the Great Opal Rush of 1895.

Good Morning,
I have just found your wonderful website.
I produce a monthly e-newsletter which is circulated to the Tourism businesses in Coober Pedy and neighbouring stations plus the Info Centres around SA & the NT.
I wondered if I could use some of your Opal info in my October Edition (Opal Month), mainly the parts in your “About Opal” section – names, spiritual info etc.
I would obviously reference it to your website noting the address so others could read your site. 
Cheers,
Sandra Harris
Tourism Officer - Coober Pedy Information Centre
