hi ,
i have found some blue clay/hard pann in 2 spots and want to start a descussion on it. one thing about it, is its huge magnatite content, could this be the bluy color. there is also lots of chalchol pyrite so it could from the copper content. if any one has info, i could use it. i am just wating for the picture, the picture below is from a diferent spot, 25 years ago, same clay though ,ust a few miles away. the rocks in the clay are mostly made up of magnatite and quartz.
very cool stuff.







they are welcome to come down and try..
