If you are getting benefit from it take it, but please don't expect to get total supplementation from it . The Majestic Earth deposit is projected to last 500 years if we use it daily 1000 times more than we're now using it annually. Even so, in 1994, I began searching for other deposits of this material. It's a long tough hunt, because right now this location in Southern Utah is the only known area on earth where harvestable levels of this material are found. You need very low rainfall, and the forests must be entombed by a glacier or volcano.
Humic shale is like the floor of a forest, very compacted dry leaves and sticks.
The consistency is like dried saltine crackers or very dry oak leaves. It's not rock. It's not fossilized. To be fossilized you need a lot of water in the area. Then, as the water soaks the plants, minerals from the water are absorbed into the plant cells, fossilizing the plant.
