Default Deep Underground, Water Pierces Solid Rock

Deep Underground, Water Pierces Solid Rock.

Deep within the Earth, water beats rock. A new study has found that jets of ultra hot liquid can carve their way through solid rock in about 200 years, hundreds of times faster than previously thought by many scientists.

These relatively quick pulses of liquid could be linked to earthquakes and volcanoes, and the finding could help to better understand and even predict these events in the future, study team member Timm John, a researcher at the University of Münster in Germany, said. "Fluid accumulates in a reservoir and is then released in pulses, like a jet through solid rock," he told OurAmazingPlanet.

When two plates collide, one slides beneath the other, a process called subduction. Intense heat and pressure gradually forces out water, which rises into the Earth's mantle and helps create magma. This molten rock fuels the explosive volcanoes of the infamous "Ring of Fire" — water, as a superheated gas, provides the power for massive eruptions in these areas.


The research team descending China's Tian Shan Mountains, where they found evidence that super-heated water can pierce rock deep underground in 200 years time.

Previously, many scientists pictured the subducting slab's liquid release as being continuous, like a wet sponge steadily leaking water onto a piece of paper. But the new study, published in May in the journal Nature Geoscience, shows it comes in spurts, like what would happen if you squeezed the sponge, John explained.

John and his colleagues arrived at their findings by analyzing the mineral structure of a fossilized "vein" through which liquid passed when it was 43 miles (70 kilometers) underground, some 315 million years ago. They found the rare rock structure high in China's Tian Shan Mountains. The mineral structure indicated that the water had passed through very quickly, geologically speaking.

The study is consistent with research on volcanoes, which shows that magma can move long distances in hundreds of years, much more quickly than expected, John said.

Water has a very potent wear action. It's used in industry in some cases to cut steel, to blast and remove paint; not just any paint, epoxy paint. Paint that is mixed from two part chemicals for harsh environments such as salt air, oceans, on oil rigs and platforms.

That paint is made for special purposes and is highly durable to everything but a blow to it. It tends to withstand salt air and water, electrolysis action to some degree, especially when aided with rectifiers, most chemicals, and weathers when older in a form of powdering that provides a self cleaning surface. While the paint is tough, it's rough to remove. In most cases, black blasting sand is used, but in rare cases where sparks are a concern, water blasting is used instead.

Depending on the method and the equipment, steel can be cut with water as easy as a cutting torch. Only the tip is usually ceramic lined to withstand the wearing action while directing the water blast to it's target.

That nature duplicates the process is not out of bounds at all.

My Older Brother use to do "Water Drilling" into rock for a Living. The water is that high pressure that it would just cut through your body if your body touched it. I don't know if they use it much now days though.
