The TerraCore Core Imaging Spectrometer™ (CIS™) can scan up to 1500 meters of core per day, keeping pace with most drilling programs. Interpretation of spectra is semi-automated when project geology is identified, allowing fast turnaround on results relevant to your exploration or resource project. Completed mineral maps and abundance data are uploaded to ALS CoreViewer™, allowing online examination of core photography and hyperspectral mineralogy at site, head office, or anywhere your geologists might be located via secure web- based distribution.
The CIS™ is a continuous hyperspectral core scanner that generates mineral maps at 1mm spatial resolution. Each pixel contains the full spectral signature from the VNIR (380-1300nm), SWIR (1300-2500nm) and LWIR (7500-12000nm) with a 5nm spectral resolution.
This enables the identification of fine-grained alteration minerals that are often not distinguishable by eye, as well as changes in composition within a single mineral type. This can be important in the clay minerals, where composition adds more information to mineral assemblages than presence or absence alone.
All data that can be displayed in CoreViewer™ is archived in perpetuity, guaranteeing digital access to core that may be stored on site. Access to the CoreViewer™ archives is free to ALS clients via Webtrieve™.
Yes, rock chip samples (i.e. crushed samples) can be scanned with the CIS™. Alternatively, hyperspectral scanning with an ASD TerraSpec® Mineral Analyser can be performed on chip samples.
ALS can perform TerraSpec® scans with our characteristic quality and traceability. We partner with aiSIRIS™ to provide interpretation of TerraSpec® spectra.MORE INFORMATION
