[QUOTE="Hawkear, post: 651648, member: 4728"] If you cannot tell with the a scrape as suggested by WalnLiz, look up a geo map of the area it was found in. That should tell you the age of the bedrock where you found it. (Presuming of course the specimen is bedrock). If the age of the rocks are earlier than Carboniferous or Devonian, they are not coal bearing as the rocks of earlier periods were laid down in the time before land plants. Most of the bedrock of Australian gold fields belong to those earlier epochs. [/QUOTE]
