TOP WOOD FOSSIL SPECIMEN MINED 1986

RARE BOULDER OPAL FOSSIL WOOD REPLACEMENT

Source Blackgate Queensland opal fieldsAUSTRALIA

Mined in 1980 and has been in family collection ever since

The circles that you can view are called Ooids orooltic .

These are sedimentary ironstone with spherical growths .

These ooliths appear to have formed in quite shallow, moving water in which chemical precipitation of iron compounds predominated

So we can assume this wood specimen fell in shallow waters in ironstone country which is well represented in Queensland.

Ooliths consist of concentric growths around a nucleus, which may be a minute quartz grain with inclusions.

THIS OPAL MINED 1986 AND NOW IN GOLD COAST OPAL AND GEMSTONE MUSEUM
