A tiny grain helps reveal the history of a rock

25.03.2013
Researchers can use the mineral rutile to learn about rock types and their history. Two articles published in the highly respected journal “Geology” now present a new application of a method for more easily tracing the mineral rutile. The co-authors of the articles are researchers at the University of Gothenburg.
Rutile is used in ceramics and paints, but is particularly useful for finding out about the history of a rock.

Where mineral deposits are found, rutile is often also present. The new methods therefore bring opportunities for strategies to find other mineral deposits, such as gold.

Until now, rutile has been a relatively unknown mineral, despite not being rare. For example, rutile can be found on most sandy beaches around the world, including in Sweden.

“It’s incredible to see how little attention was paid to rutile until around five years ago,” says geologist and researcher Thomas Zack, from the University of Gothenburg’s Department of Earth Sciences, who has devoted much of his scientific career to studying the mineral.

Now, geologists can identify rock types containing rutile and follow the changes in temperature and pressure that they have been exposed to throughout its history, even if rutile is barely visible to the naked eye. Previously, researchers had to investigate considerably more rutile-bearing samples in order to carry out analyses.

“But now we can identify the rock from which the rutile originates, even if we only have a tiny grain of rutile,” adds Thomas Zack.

New method produces fast results
The new method is called “Laser Ablation ICP-MS”, and produces results much faster than previous methods.

“In analytical terms, this is one of the most important analytical instruments at the Department of Earth Sciences here in Gothenburg,” concludes Thomas Zack.

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...

Im Focus: Nanorobots propel through the eye

Scientists developed specially coated nanometer-sized vehicles that can be actively moved through dense tissue like the vitreous of the eye. So far, the transport of nano-vehicles has only been demonstrated in model systems or biological fluids, but not in real tissue. The work was published in the journal Science Advances and constitutes one step further towards nanorobots becoming minimally-invasive tools for precisely delivering medicine to where it is needed.

Researchers of the “Micro, Nano and Molecular Systems” Lab at the Max Planck Institute for Intelligent Systems in Stuttgart, together with an international...
