Re: What I expect from Walther's Law for Delta Formations
That's basically what we get under, in and around mineable Coal Seams 2 and 4 in the Witbank Coalfield. Both these seams have lobes of channels and overbank deposits at the base of transgressive beach sands. And they split into different seams and come together again, depending on where the deltas were and what happened in the "swamps".

Re: What I expect from Walther's Law for Delta Formations
In my country, very similar, except that it happend in a fresh water environment with a big freshwater lake in the middle and that the coal deposits were formed during the Late Carboniferous (few lenses) , the Permian (most of the coal) and Early Triassic (big, "coaly" deposits such as the Waterberg coal).

In SA we don't find Cretaceous coal at all.
