Summary:A procedure is described which can yield chemical analysis for 15 elements from inclusion fluids trapped in quartz. Problems of contamination and adsorption have been overcome, following a study on the adsorption of ions released during crush-leach analysis on to the new quartz surfaces generated. Analytical methods used are AAS, flame emission spectrometry, ICP, MS, fluorimetry and specific ion electrode. Preliminary results on inclusions in quartz veins from both low- and high-grade metamorphic rocks show good agreement with theoretically predicted compositions from fluid-mineral equilibria for Na, K, Fe, Mn and Zn, though Ca and Mg are sometimes present at higher levels than expected.
