Origin of Boulder Opal

"The Boulder Opal comes from the Queensland region of Australia. More specifically, the Boulder Opal is found in southwest Queensland in Quilpie, Yowah and Eromanga.
The sedimentary rocks in this region date back to the Cretaceous period. The rock therefore comes from a period that began around 145 million years ago at the end of the Jurassic period and ended around 66 million years ago at the beginning of the Paleogene. Over the course of time - well into the Tertiary period - weathering processes released silica from the marine mud with its microorganisms, which was deposited in the water-impermeable rock crevices and cracks. The constant change of moisture and subsequent evaporation ultimately led to the solidification of the silica and thus the beautiful opal."
