The Role of Multi-Element ICP-OES in Greenstone Gold Pathfinder Exploration

Geochemical Vectoring in Archean Greenstones

Primary gold mineralization in the Lake Victoria Goldfields is structurally controlled and rarely occurs in isolation. Mineralized hydrothermal fluids introduce pervasive pathfinder element suites that create widespread alteration halos extending hundreds of metres beyond narrow quartz veins.

36-Element Analytical Suites

Using inductively coupled plasma optical emission spectrometry (ICP-OES) following multi-acid digestion, RVA Labs detects pathfinder signatures (As, Sb, Bi, Te, W, Cu, Zn) with sub-ppm precision. Geologists utilize element ratios (e.g. As/Sb and Bi/Au) to map temperature gradients and pinpoint deep-seated feeder structures.

Quality Verification

Calibration curves are verified using certified secondary multi-element standards (OREAS and AMIS matrices), ensuring reliable multi-element data across expansive regional soil and trenching campaigns.
