Find Out More About Geochemistry and Hyperspectral Data Analysis
Spectroscopy is the study of the absorption, reflectance, and emission of electromagnetic radiation (e.g., light) by matter, measured as a function of wavelength (or frequency). It is used as a tool for characterizing the structures of atoms and molecules by…
pXRF has many applications both within and outside of mining and mineral exploration. In no industry has a vendor ever told a client to take the pXRF, point, shoot, and voilà – you now have a robust dataset that is…
Perhaps a bit unconventional for these blog posts, but I want this to revolve front and center around this amazing resource I found from ALS Labs in the depths of my hard drive… a periodic table of the elements that…
As discussed in our first installment, orientation studies should enable the selection of optimum field, laboratory and interpretation procedures. Ideally, these procedures should allow for the clear resolution of significant anomalous patterns, with as little overlap as possible between anomalous…
Orientation survey. Of course you *should* know what this term means… you think to yourself… Stop googling for half baked answers and stay tuned this January to our blog, where we are going to break down this term and show…
Haven’t conducted a pXRF program in awhile? No worries, this post has you covered… to remind you to never ever forget to calibrate your equipment. Like any geochemical program, you’re also going to need to setup a rigorous QA/QC program…
A common comment that we receive is that ‘spectral is great for porphyry and epithermal, but it cannot help with other deposits.’ At LKI Consulting, we wholeheartedly disagree with this statement so for our last Spectralucation July post we would…
If you are unaware, hyperspectral data is renown for producing mineral data; biotite, white mica, tourmaline, sulfates, carbonates, Fe-oxides… the list is long and diverse. However, spectral datasets also yield “composition” data, namely crystallinity and wavelength data. In this post…
Fig. 1. Montmorillonite spectra celebrating Spectalucation July. The y-axis is reflectance (%) and the x-axis is wavelength (nm). Our blog posts thus far have concentrated more on geochemistry and general themes so we thought for July… let’s get into some…
Although characteristic of Carlin-type deposits, invisible Au in pyrite is also observed in epithermal (low- and high-sulfidation) and porphyry deposits. Some famous examples include Yanacocha (Peru), Pueblo Viejo (Dominican Republic), Brucejack (Canada), Lihir (Papua New Guinea), and Dexing (China). Perhaps…
