Services

FAST. AFFORDABLE. COLLABORATIVE. CREATIVE.

We provide analytical and support services to help you reach your research goals.

Lithic and Ochre Provenance

Where did these stone tools come from? What are they composed of? We apply cutting-edge analytical techniques and sophisticated statistical approaches to ensure you have the most confidence in your results as possible.

Field Support

Let’s put our boots on the ground. Over ten years of fieldwork experience in contexts ranging from Hawaii to Belize to Belgium and focussed in the Pacific Northwest can help you get the job done.

XRF Rentals

Are you certified by NRCan to operate an XRF? We provide easy access to instrument rentals at extremely affordable rates so you can collect your own data. We also are more than happy to help you interpret it!

The nitty gritty…

Archaeological materials we analyse:

  • volcanic glasses (e.g., obsidian; McMillan et al., 2019)
  • fine-grained lithic materials (e.g., extrusive volcanics; Weis et al., 2020)
  • chemical sediments (e.g., cherts; Allan and McMillan, 2021)
  • clastic sediments (e.g., tuffs, siltstones; Bonjean et al., 2015; Allan and McMillan, 2021)
  • oxide and sulphide minerals (e.g., ochres)
  • bioapatite (e.g., bone, McMillan et al., 2017 and 2019)
