Exploration Activity: Soil Sampling At Valley Of Ten Thousand Smokes Region Area (Kodosky, 1989)
|Exploration Activity Details|
|Location||Valley Of Ten Thousand Smokes Region Area|
|Exploration Technique||Soil Sampling|
One-hundred twelve samples were collected from relatively unaltered air-fall ejecta along two Novarupta Basin traverse lines (Fig. 5). One hundred eighty-two samples were taken from active/fossil fumaroles in Novarupta Basin (22 sites, Fig. 5), fossil fumaroles (41 sites) and air-fall tephra (2 sites) within and immediately adjacent to the remainder of the VTTS (Fig. 6). In total, 294 samples were collected from 127 sites and stored in sealed zip-lock bags. Mercury analyses were performed on air-dried ( < 80 mesh fraction) samples using the Jerome Instrument 301 Au-film Hg degrees detector.
