coachtim Posted January 7, 2007 Report Share Posted January 7, 2007 Can anyone help with the ID of this rock? It makes my beeper nuts in discriminate mode or not. I am pretty new at this and it does not make sense. Not very heavy in fact light? Quote Link to comment Share on other sites More sharing options...
BIGFOOT Posted January 7, 2007 Report Share Posted January 7, 2007 Definitely a Volcanic hot-rock.......andesite or Basaltic. Quote Link to comment Share on other sites More sharing options...
whats4supper Posted January 7, 2007 Report Share Posted January 7, 2007 it looks like biotite (the flat gray/green part) and sulphide ore (the bluish/reddish/luster part). sulphide as in copper, antimony, silver, some gold maybe, and iron. have it assayed if you think it carries values.other tests would be qualitative- all the minerals included.quantitative- percentages of each mineral.reductive- how to treat the ore to get out the desired minerals (no such thing as 100% extraction), and what may be considered the primary ore or the secondary ore.if the rock is light in weight, then the part that I described as sulphide ore would be schist. mostly mica and muscovites, a form of metamorphic rock. while not gold bearing in its form, it can be an indicator of gold bearing areas. sometimes, nuggets and small placer gold get trapped up in its platy formations. the main component of the mineral is beryllium, which is used in nuclear bombs and rockets, or as an insulator in toasters. Beryllium is also found as the gem stone Beryl. Quote Link to comment Share on other sites More sharing options...
