Curtin, the researchers found signs of 'strange' new platinum rhodium thermocouple

Including curtin university scientists, an international research team in the meteorite crater of two ancient records not found platinum-rhodium thermocouple & other Ghost & throughout; 。

today ( Date of TBC) Published in the journal of geology of this new study is the first to record a new forms of evidence of platinum-rhodium thermocouple monazite, this kind of monazite in meteorite impacts generated by the huge pressure to exist on earth.

the study's co-author, curtin space science and technology center, an associate professor Nick timms says international team using electron microscopy at high magnification in Germany and Canada crater tiny pieces of rock, and found that their findings.

“ However, platinum rhodium thermocouple restored to the original crystal structure, rather than keep this new form of structure, and when the new platinum rhodium thermocouple is only a fraction of a second, because the shock waves through the earth is close to zero, it left a unique crystal clues.

“ We are about to find out a new kind of platinum-rhodium thermocouple, but there is an obstacle, because platinum-rhodium thermocouple on the surface of the earth is not stable, easily into monazite again. So, we've really only seen, may only see the & other; Ghost & throughout; 。

new platinum rhodium thermocouple evidence is found in a meteorite crater - two old Germany's Ries the Haughton Crater and the Canadian arctic - impact structure But until it is difficult to find the platinum rhodium thermocouple was found to be stored in the rocks, scientists can give it a proper name. Dr.

Curtin alumni Timmons Erickson, now at the NASA Johnson space center, is the lead author of the study, the study & other; Shock produced by high pressure ( 洛杉矶,Ce、Th) PO4 polycrystalline phase genetic type of monazite microstructure reveals & throughout; , can be found here.
