Hi WhatsupwithBas,

One of the biggest differences with our little differentiated sill compared to other more famous layered mafic intrusions, complexes is the scale. The bushveld complex In South Africa is over 9km thick. The stillwater complex in Montana is perhaps 5kms. Skaergard, Greenland is in kilometres. Kemi, Finland is over 1km. The great dyke of Rhodesia is friggan huge in Zimbabwe. Perhaps Sudbury could be thrown in as well which from memory is over 1kms thick but its genensis is different to Mt Thirsty. Ours is perhaps over 100 - 200m thick, yet still we have some of the layered differentiation and partial melting end products which all the above have. Hopefully we have a nice concentrated layer of PGE's.

In the Bushveld complex, the PGE's are mostly crammed into a 46cm section, the Merensky reef from a thickness of differentiating 9 kms of mafic to ultramafic melt in the bushveld complex. I remember very well handling a piece of Merensky reef during my university days 40 years ago, and it was truly an underwhelming experience after finding out that approx 90% at the time of the worlds PGE's were in that reef. I still think over 50% come from there. My point is that PGE's in ore doesn't mean that they look particularly mineralised. This is the risk of interpreting core to grades. Often it is the same with gold mineralisation.

Even though our differentiated sill is small compared to its larger peers, it may well have the goods in a distinct thin reef of PGE's. Many of the above intrusions have different chemistry for example, almost all have chrome, we don't. We seem to have more copper which may be unrelated to the differentiation but more related to other hydrothermal fluid movements.
