Summary

[edit]
Description

Another picture of greensand, this is the same sample as the last one, but one that was wetted down ... what follows is the rest of the post from the previous picture of greensand....greensand dug from my backyard, which at one point was on the ocean floor...and at a point in the future will return to that state. Our local greensand is composed of rounded marine sand, glauconite (the greensstuff), and geothite (small brown/black particles). One of the strawbale walls of my bathroom is plastered using using local brown clay and greensand to achieve a lovely olive green wall...a bit sandy since the rounded sand particles have no "bite."
