Re: Walther's Law and Delta Formations
About the siliciclastic muds, what you uncovered so far is already far more detailed than anything I know. I just assumed that they formed from the runoff from land, and that they occur further out from the coast than beach sand because they're smaller, lighter particles and will only fall out of suspension in quieter waters (i.e., no waves crashing through a surf onto a beach).

What is the source of your chart? The chart's title is "Mineral assemblages of common igneous rocks and their relation to the interior structure of the Earth", but it includes many non-igneous rocks, like limestone and sandstone and shale and slate. Also, I can't make sense of the chart's organization - is it actually three separate charts? And why are there notes at the bottom about the moon?
