[QUOTE="user 4386, post: 632310, member: 4386"] A bit like "indicator" and "reef". The first is any pyritic, quartzose or graphitic seam in slate (eg the "pecilmark" at Ballarat East - not an indicator of gold directly, just an indication of how many metres you are from the main quartz reefs - described by Mark Twain - see #9953 in Australian History). I find that most people dont realise that in the 1800s "reef" meant hard rock (eg sandstone, quartz). It confuses a lot of people in deep lead reports (another annoying term) because it is commonly referring there to a hard bed of sandstone or quartzite that they could not easily dig out wth a pick and shovel. So "struck a reef and followed it" often means different to what modern readers think! [/QUOTE]
