VOLCANIC ASH BECOMING
CLAY ON EARTH Ð
~D ´ [ N j C d A e
I learned this from
living in active volcanic lands of 3 islands in Hawaii & visiting dozen
other countries, most with some clay soil I saw many patterns. Then I grew this ÔrareÕ theory of earth
making clay from volcano ash, mentioned in only in 1 geology textbook of a
dozen IÕve read to find earths source of making clay Ð called ÒgeomorphismÓ how
earth makes minerals.
The known source
of hi mineral ash are 1000s of volcanic eruptions sending zillions of tons of
ash clouds in winds & falling down, some blowing 1000s of miles away, even
darkening sky & chilling climate.
I believe that ash makes common & rare earth clay, in deep deposits,
caves & scattered widely on lands blowing locally & hi downwind seen in
layers of strata revealing aging with soil & sands; then washing like
sediment down toward oceans. IÕve seen clay in tides coming & going from streams into bays.
ThatÕs been
found for centuries, & millennia clay used in pottery, sometimes knowing
the source, even a nearby volcano, & seeing ash blowing & falling
around. Or if clay diggers have
tracked the volcano it came from to deposit there. I saw volcanic ash falling in Portland, OR after Mt.St. Helens erupted in May 1980. 1000s
of tons of that ash flows down west in wet mud, & blew east falling on
lands hurting & later fertilizing crops growing in ÔnewÕ mineral rich fertilized soils. The mineral in ash determine it fertility
for lands it falls on, we can see its colors & feel textures. Heavy ash falls get buried & stay
pure, with no soil, then are minded to use in pottery & other industrial
process.
So colors &
composition of ash Ð clays are extremely varied, commonly grey, red or tan,
easily mixing with soils in wet tropical & temperate bioregions, effecting
soil fertility with the minerals in clay directly on plants, roots, microbes, worms,
fungus & composting in the soil, helping or hurting their whole cycles.
Some ash/clay
is greatly valued for growing
plants & making fertile soil,
& some is toxic, depending on the minerals in the ash/clay composition. Each color: red, black, brown, yellow,
tan, white, blue & green have different
mineral combinations. Some native clay users know how to use their local &
even imported ash/clay varieties in many ways.
Like IÕve seen
vast red clay soil around & down wind from some volcanoes in Hawaii, 3
island, Guatemala, & Costa Rica, where we got lots of tan clay from mtn
river bed to test out. Near the brie-brie Native Indian in hill country.
However the variety of ash/clay is extreme (infinite?) in mineral
contents & fertility it adds or hurts soils it fall or flow onto in 1000s
of bioregions. This approach to natural to ash/clay & soil
fertility we often commonly use (for millennia) in ÔPerma- cultureÕ the ancient
design science of organic homesteading in family farming systems integrated
with local ecology, water flows, wildlife, soil fertility & human needs.
Now Azomite clay with many trace minerals mined in Utah is widely used on farms
in North American & elsewhere for soil fertilizer & animal feed needing
hi minerals it contains.
