UJ researchers find exotic micro-mineral compounds in Hypatia stone<\/a>: <\/p>\n

UJ researchers make interesting discovery in Hypatia stone<\/p>\n

Researchers at the University of Johannesburg (UJ) have found exotic micro-mineral compounds in the \u2018Hypatia\u2019 stone that are not known to occur on Earth, elsewhere in the solar system or in known meteorites or comets.<\/p>\n

Professor Jan Kramers and Dr Georgy Belyanin from the UJ PPM Research Centre at the Department of Geology made the discovery.<\/p>\n

\u201cAnalyses on a small pebble found in south-west Egypt cast significant questions on a widely-held view about the primitive pre-solar dust cloud which our Sun, Earth and other planets were formed from,\u201d UJ said in a statement on Thursday.<\/p>\n

Lead author of the study, Kramers was recently recognised as a \u201cLeading international researcher\u201d (A-rated) by the National Research Foundation.<\/p>\n

Kramers is a geochemist currently specialising in dating techniques (especially for hominin fossils) and analysis of extraterrestrial objects.<\/p>\n

\u201cIn 2013, Kramers and his co-authors announced that the Hypatia pebble found in south-west Egypt, was definitely not from Earth.<\/p>\n

\u201cBy 2015, other research teams had announced that the stone was not part of any known types of meteorite or comet, based on noble gas and nuclear probe analyses,\u201d UJ said.<\/p>\n

Kramers said the Hypatia was formed in a cold environment, probably at temperatures below that of liquid nitrogen on Earth (-196 degrees Celsius).<\/p>\n

\u201cIn our solar system, it would have been way further out than the asteroid belt between Mars and Jupiter, where most meteorites come from. Comets come mainly from the Kuiper Belt, beyond the orbit of Neptune and about 40 times as far away from the sun as we are.<\/p>\n

\u201cSome come from the Oort Cloud, even further out. We know very little about the chemical compositions of space objects out there. So our next question will dig further into where Hypatia came from,” Kramers said. – SAnews.gov.za<\/p>\n
