[QUOTE="Hawkear, post: 668697, member: 4728"] Daylesford geology maps indicate that the bedrock of the area apart from cappings of basalt is made up of quartzites, sandstones and slates. All can have a speckly or glittery type appearance, so a bit hard to tell even from a photo whether the glittery bits are micro quartzy crystals as in quartzite or sandstone or micro mica flakes or pyritic crystals as in some slates. Suggest get a good loupe and examine it closely to check whether they are crystals or flakes. Even try to prise one off with a needle might be telling as to what they are. My two bob would be on slate with micro mica flakes. [/QUOTE]
