Lar, stellar post my friend and you've layed it out in laymans terms, you continue to offer up the necessary "tidbits" freely of your time to help your fellow shareholders to help with our understanding of the the forces that gave us what we are finding. Of particular interest is the direction of flow layout, i've been wondering just how we can tell which way the flow travelled and you just answered.
This wholesale deposition of chromite also indicates that the chemistry of the bulk magma was changing from ultramafic towards mafic character. Although the distinction is not really important, we begin to move away from mineral deposits that are associated with ultramafic intrusions, and we start to see those associated with mafic magmas. Once all the chromium was used up, the "pecking order" of reactivity to available oxygen left titanium, vanadium, and iron at the top of the list. The fact that NOT found a large deposit of these NE of the FWR chromite suggests that the magma flowed onwards in that direction. We're not likely to find any more nickel over there, the sulphides having been long since eliminated from the magma. We're not likely to find any more chromite over there, either. Unless there's a new point of intrusion up there, with its own geochemical sequences. But somewhere in between could be a rich PGE zone.
The posts' a keeper for the file Lar, thanks for that, a jewel first thing in the am.
Regards
Rob
