By probing chemical processes observed in the Earth's hot mantle, scientists have started developing a library of basalt-based spectral signatures that not only will help reveal the composition of ...

By trying to tease out signatures related to mineralogy and bulk chemical composition - for example, how much silicon, aluminum and magnesium are in a rock - the geologists can tell a little more ...

And because RNG has the same chemical composition as natural gas, it can serve as a ‘drop-in’ fuel that involves minimal ...
