Stunning Photos & # 39; deepest depths – UQ News



The lighting of the "plumbing" inside the volcanic investigation is that scientists better understand the volcanic eruptions and eruptions.

A study by the University of Queensland examined crystals in the famous Mount Etna in Italy to explain how the magma surface moves.

Teresa Ubide, Ph.D. of the UQ School and Environmental Sciences, said this study aimed at better understanding volcanic systems and improving the control of volcanoes.

"I think that we call magma plumbing systems" because of the inner nature of the volcanoes ", we can better interpret the magma movement signals at our feet," said Dr. Ubidek.

"Volcanic eruptions of the past may provide contextualization of magmatic transport information to a better response to future monitoring signals, earthquake measurement seismic measures."

Dr. Ubide and his team have studied the chemical composition of the crystal volcano in a chemical model called "zoning zoning".

Dr. Ubide and his team have studied the changes in the chemical composition of the volcanic kala"Volcanologists and mineralogists have crystallized zoning for decades when crystals are rapidly formed."

"But because the origin and implications of the magma-sector-crystallized areas were not very misunderstood, they were generally not considered in the volcanic processes.

"We have now found that there are not only magmatic records and specific eruptive triggers, but also information on the speed of the magma transport surface."

This research, which works to analyze volcanic crystals, uses high-tech ultraviolet laser (similar to eye surgery technology). UQ Radiogenic Isotope Facility.

"We're using a cold glass laser to get rid of the thin layer of crystalline surfaces," said Dr. Ubidek.

"This small amount of material is inserted into the mass spectrometer, a tool that measures the composition of" trace "elements, which can be less than 0.1% of the original object.

"Changes in the trace elements of these crystals are very sensitive to processes that occur inside volcanoes, magma storage and cooling, magma mix, magma transport and magma surface rise.

"It is an amazing photo that is taking place inside the volcano, it provides essential views of its interior plumbing system and helps us to understand such horrible natural miracles."

The research is published jointly with the Italian Institute of Volcanology of the University of the INGV-Rome and Sapienza Geochemistry and Cosmoquímica Act (DOI: 10.1016 / j.gca.2019.02.021).
