Many of these nickel-iron ores appear in 2.9 to 1. 8-billion year old rocks called komatiites, which formed from very hot magma ejected from deep within the earth.
For the investigation, the platinum content of lava flows called komatiites was analyzed over extended periods of time.
Here we use thermodynamic calculations to show that Fe - and Si-rich fluids can be generated by hydrothermal leaching of low-Al oceanic crustal rocks such as komatiites.
The international research team used synchrotron technology to study the chemical composition of komatiites - ancient volcanic rocks thrown up from the planet's mantle.
"We found that the oldest komatiites have the lowest platinum content.
