Rock GCC Series Part 4: Close-up details of patterns and textures in water-worn sedimentary seashore rocks. Being unable to travel very far afield right now because of the Covid 19 situation and restrictions, I am enjoying virtual trips to places that I have visited in the past. So some (not all) of the images in these current rock postings may have appeared on my blog previously, accompanied by more information, but I thought that they were worth airing again in their own right.

I love the color scheme of these rocks. The blue and buff is a serene combination.

Thank you, Claudia. I am wondering if the colours are related to different sediment particle size with the blue being finer mud and the buff more sand like.

The blue and buff reminds me of rocks I remember seeing when I was young, the creek uncovering them. We lived in an area of limestone, the results of being undersea millions of years ago, but this was not limestone. I wish I knew what it was, your rocks brought back the memory.

These rocks belong to the Cork Group of rock strata, most probably the White Strand Formation which is comprised mainly of Namurian (Upper Carboniferous) sandstones inter-bedded with brittle, commonly pyritic grey-black mudstones.
