Three Methods To Make Rapid Petrified Wood

Introduction
I was taught that it takes millions of years to form
petrified wood. Consider this quote from a geology website:
“The petrification process can take
millions of years to complete. During this time, the minerals slowly replace
the organic matter in the wood, cell by cell. The result is a rock-hard replica
of the original tree.”[1]
Has anyone ever observed this alleged process over millions of years? No! This is pure speculation and arbitrary at best. I like to ask, “what
experiments have been run that verify it takes millions of years to form
petrified wood?” Again, there are none.
On the flip side, did you know that we can make petrified
wood quickly! It doesn’t long ages, but can be made in weeks to months.
Some petrified wood is being manufactured for home products (e.g.,
flooring) and can be ordered through local home goods stores. Let’s look at a
three of these methods of rapid petrified wood formation—some of which have been known for some time but others
have been explored in more detail in recent decades. But first, what is petrified
wood?
What Is Petrified Wood?
Petrified wood is wood that has been preserved by
mineralization. The original organic material is replaced by minerals—partially
or completely—while retaining the original cellular structure of the wood. This
is not to be confused with coalified wood—which is a different process of
converting wood to coal, which can be made quickly as well.
This petrifying process occurs when wood is rapidly buried or submerged
[to seal out oxygen and prevent rapid decay and degradation of the wood’s fine details]
in mineral-rich water. This allows dissolved minerals such as silica, calcite,
or iron compounds to replace the pore spaces and cell walls. As the organic
material decays or is removed by water transport, minerals precipitate in its
place, forming a stone-like replica of the original wood.
Petrified wood is therefore not simply wood turned to stone,
but a detailed mineral “cast” that preserves growth rings, vessels, and
microscopic anatomy. The resulting fossil can be as structurally detailed as
modern wood, yet composed entirely or largely of inorganic mineral matter. Of
course, it is much heavier than the original wood, being that is now rock.
Method 1: Silicification By Silica-Rich Fluids[2]
This first method utilizes wood that has been mineralized
rapidly through silicification by silica-rich fluids (SiO2—think
of “quartz”), particularly in hydrothermal or volcanic settings. The point here
is that heat is involved to speed the process of converting the wood material to
minerals.
When wood is buried or submerged in water that is chock full
of dissolved silica, then the silica replaces cell walls and pore spaces while
the organic material simultaneously decays or it removed. The heightened
temperature and alkaline pH quickly increase silica solubility and reaction
rates. So, the silica precipitates quickly as amorphous silica and then later
recrystallizing into microcrystalline quartz. Don’t let the fancy terminology
scare you. It simply means the process goes fast—very fast.
Laboratory experiments and field studies of hot spring
environments show that cellular-scale replication of wood anatomy can occur on
timescales of months to years, preserving microscopic structure before
mechanical collapse. So actual scientific studies show this doesn’t require
millions of years, but can be done quickly. This process does not require long,
slow periods of diffusion over millions of years but instead depends on early,
rapid mineral infiltration after burial.
This is exactly the type of conditions we expected at
certain phases and places from the global Flood of Noah’s Day. Most of the
petrified wood we find in the world today is associated with Flood rock and with
volcanic layers—showing the heat was present to rapid formation of petrified
wood. During the Flood, there was immense volcanic activity—especially when
considering continental shifting and mountain building phases (e.g., Genesis 8:4-5;
Psalm 104:8-9).
Second Method: Carbonate Permineralization[3]
Wood can also be mineralized rapidly through carbonate
replacement which is also called permineralization. A carbonate
material basically has a “CO3” attached to it. It involves minerals
such as calcite (CaCO3), dolomite (CaMg(CO3)2)—which
has calcium and magnesium, or siderite (FeCO3) which has iron. The
carbonate materials are the mineral that make the wood into stone instead of
silica (SiO2) from the last method.
With this process, it occurs in carbonate-rich waters,
especially in anoxic (i.e., oxygen is kept out) or microbially active
environments such as swamps, deltas, or shallow marine sediments. Then the
dissolved calcium, magnesium, or iron precipitate within wood tissues. This
process of carbonate precipitation is very fast under alkaline conditions and
can occur before the wood collapses or fully decomposes.
Scientists have learned from experimental studies that
carbonate mineralization of plant material can occur in months to years,
producing rigid, stone-like replicas of wood structure. This mechanism is well
documented in coal measures and flood deposits. Interestingly, unlike the last
method, this one does not require high temperatures or silica-rich fluids. Again,
these are the types of processes that were expected at certain phases and
places during Noah’s Flood.
Third Method: Microbially Mineralization[4]
A third rapid pathway is microbially mediated
mineralization, in which bacteria play a direct role in fossilization. Think
of them like a catalysts that speeds up the process.
Microbial biofilms colonize buried or submerged wood and
alter local chemical conditions—by basically putting a boundary around it. These
changed chemical conditions could include pH, redox state, and ion
concentration.
These “micro-environments” act as sites for mineral
precipitation, speeding up the deposition of silica (SiO2),
carbonates (CO3), iron minerals, or phosphates directly onto cell
walls. Lab experiments revealed that microbial involvement can speed
mineralization by orders of magnitude compared to abiotic processes (i.e.,
processes that are only physical/chemical without biological help).
The result—the mineral replication of biological tissues
occurring in weeks to months. This mechanism explains the exceptional
preservation of fine cellular detail observed in many fossil woods and plant
remains. Again, these are the conditions that are expected during the year long
Flood of Noah’s day.
Conclusion
Although many are taught that it takes long ages of millions
of years to form petrified wood, this is simply not the case. There are
multiple methods that can do it weeks, months, or at most a couple of years.
As mentioned, one of these processes is used to make
petrified wood home goods if you want a beautiful and unique flooring in your
home (though it does have its costs!). So these three methods have been known
for a while and its time to start spreading the word about the rapid formation
of petrified from a scientific perspective.
