Aqua Regia for Soils and Sediments
The rare earth elements and lead isotope concentrations add new dimensions to super trace data. REEs may be useful pathfinders despite reflecting only the labile component, while Pb isotopic signatures can be used in fingerprinting and hydrothermal fluid history.

Hydrogeochemistry
ALS offers a reliable and cost-effective water analysis package with optional anions by ion chromatography and a full suite of physical parameters. Trace elements and metals require at least 50mL water. Anions and physical parameters require at least 500mL water. Sampling kits may be purchased in some locations, please enquire.

Biogeochemistry
Careful selection of plant species is important as biological effects control geochemical response. ALS provides additional vegetation preparation services such as separating the plant parts of interest from waste material. Please contact your local lab to discuss your specific project goals.

Halogen analysis ›
Evidence suggest halogens (F, Cl, Br, and I) play an important role in hydrothermal ore deposit formation and therefore have the potential to be useful elements for mineral exploration. With advances in analytical methodologies, halogens are now able to be routinely measured, providing another geochemical tool for explorers. Soil, vegetation and water can be routinely analyzed for halogens.

Ionic Leach™
It is a static sodium cyanide leach using the chelating agents ammonium chloride, citric acid and EDTA with the leachant buffered at an alkaline pH of 8.5. Nominal sample weight is 50g (wet weight, no screening). Prepared vegetation samples may be leached at a 5g sample size.

Four Acid Super Trace Analysis
ALS has lowered the detection limits on key pathfinder elements such as As, Sb, Se and Tl to near or below average crustal abundance, revealing anomalous patterns at levels previously unattainable due to technical limitations. The rare earth elements and lead isotopes are available as add-ons to expand the utility of the method in greenfields exploration.

Portable XRF for Lithogeochemistry
The crucial lithogeochemical elements - silicon, titanium, and zirconium - may be added to any ALS four acid method for a more complete element suite.
