From Longrigg Gypsum mine ,1980's I think, nice banding with Mum for scale, not sure if this is still accessible.

I like the ironstone! I was at Coalbrookdale Museum of Iron over the weekend and that suggested that at least some of the iron ore was in nodular form within the coal beds. So I am imagining it looking like that.

Indeed. I grew up in Kimberworth in Rotherham, and many large spoil heaps from Dropping Well Colliery (mining ironstone and coal) remained until 1977, when the whole area was landscaped. I remember digging out the arched bricks of an old buried coke oven when I was a kid without even realising what it was. But there are many, many heaps remaining, running in a wide belt NW from there until past Tankersley, many miles away. They look amazing on LIDAR, but not so good in real life, as they've all been allowed to overgrow in plantations. This is probably the densest set of spoil heaps:

But this is what most of them actually look like now on the ground - better to see in winter, but still very unsatisfying photographically.

Two veins running across water smoothed limestone on the NE shore of Cow Green Reservoir, just up from the old access road /slipway.

The recently-exposed Swallow Wood coal seam near Sheffield being cleaned for documentation by members of Sheffield Area Geology Trust. The seam was exposed in an abandoned railway cutting earmarked for a housing development, and was split into two leaves at this point. There are abundant plant impressions in the seam, and freshwater mussel fossils in a dirt band just above it.

Ironstone nodule in laminated mudrock:

Are these Iron Nodules similar to the nodules that you find in certain parts of the Pennines, often in stream beds or on lead mine dumps?

Saw this fault displacing a quartz vein by about a foot in the Hafodlas drainage adit today.
