An unrelated bit cool about clay from https://en.wikipedia.org/wiki/Clay_mineral.

Given the requirement of water, clay minerals are relatively rare in the Solar System, though they occur extensively on Earth where water has interacted with other minerals and organic matter. Clay minerals have been detected at several locations on Mars,[15] including Echus Chasma, Mawrth Vallis, the Memnonia quadrangle and the Elysium quadrangle. Spectrography has confirmed their presence on celestial bodies including the dwarf planet Ceres,[16] asteroid 101955 Bennu,[17] and comet Tempel 1,[18] as well as Jupiter’s moon Europa.[19]

Where is Vol. 1 ?

Fun fact: Orinoco Flow is actually about the movement of silt and sediment in river systems and its wide ranging impacts once reaching the open ocean.
