Probably some of what we call "accessory" minerals from granite for the Mogo area - they tend to be heavy. reds are possibly garnet , there may be zircon- peridot can occur if there is some basalt close nearby. It is a complex area there, with not only common sedimentary rocks but basalts of two very different ages and granite.Hi Folks,
While on the hunt for microscopic gold, I frequently observe a lot of coloured 'stones' amongst the black sand, and quartz. Grubstake spotted a few in some photos I posted of my micro-gold and suggested I post more pics here to see if anyone could do some ID's for me. All samples are sub 1mm and from a quartz sand rich creek near Mogo (SE NSW). If they were larger I'd run some hardness & streak tests & attempt some ID myself but these are waaayyyyy too tiny (for me anyway). There are reds and oranges, a blue-grey cube, pink, & a bright green (peridot?) I'd greatly appreciate it if anyone had some suggestions as to what the main ones are.
