Chapter VI: The Volcano Alchemist and the Rock Extract
Asao Shimanishi spent fifteen years trying to release minerals from rock into water. What he produced may have isolated a working phase of Earth’s life-sustaining chemistry.
In the previous three chapters, I presented the Rock–Water Circuit framework, a theory that integrates insights from geology, hydrology, biology, chemistry, and origin-of-life research. Those chapters established a central idea: the same iron–sulfur–aluminum–water (ISAW) mineral chemistry that formed in rock helped initiate life on early Earth and continues to operate today, continually reforming and releasing the mineral inputs on which all living systems depend.
This conclusion should not be entirely surprising. Any planetary energy system capable of sustaining life over immense spans of time must also contain mechanisms that continually regenerate the energy gradients on which life depends. Without such renewal, the mineral systems supporting biology would gradually exhaust themselves.
When a Human Isolated a Phase of the Rock—Water Circuit
For billions of years, ISAW operated only within the slow machinery of the Earth itself. Water circulated through rock; mineral lattices hydrated and exchanged ions with passing water; electrochemical gradients formed and dissipated; and, ultimately, this energy architecture established the conditions under which life eventually emerged and evolved.
Then, in 1977, after more than a decade of solitary experimentation, a Japanese engineer succeeded in extracting the system’s mineral core, separating a geologically generated chemistry from its host rock and rendering it portable in liquid form.
His name was Asao Shimanishi.
What is remarkable about his accomplishment is that most scientific discoveries either identify previously unknown processes in nature or, in technology, create processes that did not previously exist. Shimanishi’s work belonged to a third, historically unusual category of discovery: he succeeded in isolating and stabilizing one of nature’s primary energy-generating systems.
This work was done by a single individual operating outside the scientific mainstream.
Reconstructing the Life of Asao Shimanishi
Over the past seven months of studying Shimanishi’s life and work, I have been challenged by the near-total lack of formal documentation of his personal life and professional accomplishments. That scarcity makes it difficult to speak with complete confidence about the full arc of his scientific journey.
What follows, therefore, is drawn from the small body of material I was able to gather: a few oral histories from people in Japan who worked with him or for his company, and a translation of what appears to have been his only public interview, published in a Japanese magazine shortly before retirement.[i] I also drew on a first-person chapter in a limited-edition Japanese book called Rock Water, written nearly twenty years ago by colleagues, based on notes they had taken during lectures he delivered in China.
Ultimately, I do not believe that Shimanishi knew he was extracting a foundational piece of planetary chemistry. His goal at the time was much more practical. To see how he came to it, however, we have to begin earlier, with the formation of the man himself.
Asao Shimanishi was born in Wakayama Prefecture in 1926. After finishing high school in 1944, he first studied engineering, then entered Osaka Pharmaceutical College in 1946, in the difficult years just after the war. His earliest professional work was in pharmaceutical research, but the interests that would later define his life had begun much earlier. From childhood, he recalled a fascination with rocks and with the hidden processes by which the natural world seemed to sustain itself.
One story about him that has been told to me since I first began studying Shimanishi concerns an experience he had in his early thirties. Sitting near the sea in meditation one day, he noticed a tree growing straight out of what appeared to be naked stone. There was no soil, no visible earth, only a narrow crack in a granite boulder from which the trunk rose, supporting a tree in full bloom.

That event appears to have influenced his decision to turn away from pharmaceutical research. He found himself less interested in the increasingly abstract sophistication of synthetic chemistry and the rapid advances of petrochemical and polymer science, and more drawn to working with what he called “natural starting materials,” with the sense that something extraordinary might still be discovered in them.
Soon afterward, he encountered a senior colleague from his hometown who showed him what he called a “mysterious mineral”: vermiculite. He later referred to that moment as his “Encounter with the Stone” and described it in retrospect as serendipitous. He soon learned that vermiculite was the weathered form of an iron-rich black mica mineral called biotite, which contained an unusually large number and variety of mineral elements, in some analyses more than forty. Although vermiculite is more open and hydrated than biotite, its minerals still remain tightly bound within stacked aluminosilicate sheets.
He knew that common elements could be extracted from rock relatively easily with acidic or alkaline solutions, but his interest centered on the rarer trace minerals. What drew him onward was the possibility that, once dissolved as charged ions, such elements might display catalytic behavior and unusual reactivity. He also reasoned that for those minerals to become chemically active in a meaningful way, they would have to be dissolved in water. From that point on, his aim was clear: to produce an aqueous mineral solution extracted from rock.
It was a simple idea, yet difficult enough to occupy the next decade and a half of his life. Outside work, he began devoting increasing amounts of time to what he himself described as a private obsession, a “castle in the air” project with no immediate practical application and no clear commercial objective, all the while aware that those who knew of his efforts regarded him as something of a fool.
From the start, he had little success with the acids and methods he first selected. Yet he persisted for nearly fifteen years, driven by a single conviction: that a liquid solution containing broad mineral complexity might be of benefit to humanity. He tested combinations of different rocks, acids, and alkalis under varying conditions of heat and water, advancing only through failure, repetition, and adjustment, with a patience measured in years.
He became, in his own words, captivated by the stone, so much so that he compared himself to someone being sucked in by its very name, hiru-ishi, “leech stone.” Working often late into the night, he continued experimenting, adjusting equipment, and enduring a grueling private research life. He later said that he barely noticed because he was so absorbed in it, and that under intense concentration, flashes of insight would sometimes come.
The ambition itself was elemental: to extract minerals in a form that could move beyond a single volcano or spring and enter ordinary water, soil, and life.
Finally, in 1977, he produced the exact liquid solution he had sought: a spectrum of minerals dominated by iron and sulfur, with dozens of other elements appearing in minute, yet still active, amounts. He named his extract Themarox, or “Rock Extract.”
One clarification will help here. Themarox is the concentrated mineral extract itself. It is not used directly. When diluted into water, it transforms that water into what Shimanishi and his colleagues called “Rock Water.” Themarox is the source. Rock Water is the active medium through which biological effects occur.
A Historically Unparalleled Achievement
It is my opinion that his achievement is unique in the history of science. Although many scientific discoveries begin with moments of insight that then take years to develop into practical form, Shimanishi’s path was different. He spent well over a decade working by himself on a single technical problem until it finally yielded a solution.
