Dec 10, 2021· Cross section of a barite and silica chimney from East Diamante Caldera in the Mariana volcanic arc, west Pacific. The yellow center surrounds the conduit through which the hot fluids vented; the yellow color is due to a trace of iron in the silica. The chimney also contains moderate amounts of sphalerite and galena.

By combining a number of methods into one cost effective package, a complete sample characterization is obtained. These packages combine whole rock analysis, trace elements by fusion, aqua regia digestion for the volatile trace elements, carbon and sulfur by combustion analysis, and several detection limit options for the base metals.
