Objective Domain Boundaries Detection in New Caledonian Nickel Laterite from Spectra Using Quadrant Scan

Modelling of 3D domain boundaries using information from drill holes is a standard procedure in mineral exploration and mining. Manual logging can be difficult to exploit as the results may not comparable between due subjective nature geological logging. Exploration mining companies commonly collect geochemical or mineralogical data diamond core chips; however, manual interpretation multivariate slow challenging; therefore, automation any steps process would valuable. Hyperspectral analysis chips provides relatively inexpensive method collecting very detailed rapidly consistently. However, challenge such high dimensionality data’s variables comparison number samples. usually processed produce abundances generally involving range assumptions. This paper presents testing new fast objective methodology identify lithological dimensional hyperspectral data. applies quadrant scan recurrence plots. The results, applied nickel laterite deposits New Caledonia, demonstrate that this transitions downhole These are interpreted reflecting changes used an aid improve boundary detection.
