...Jun Wu; David R. Veblen Abstract Atom location by channeling-enhanced microanalysis (ALCHEMI) was used to determine the occupancy of Al atoms in the T 1o site (t 1o ) of alkali feldspar. Building on the method demonstrated by previous research, analytical electron microscopy proves to be a viable...

... (indeed, most economic gold deposits owe their origin to this mode of transport). From alchemy and later experimental chemistry and geochemistry, we have developed an understanding of the solubility and speciation of gold in aqueous liquids and other crustal fluids. This knowledge informs us about...
