Multi-sensor analysis of complex geologic materials

摘要

Systems and methods for analyzing an unknown geological sample are disclosed. The system may include at least two analytical subsystems, and each of the at least two analytical subsystems provides different information about the geological sample. The data sets from various analytic subsystems are combined for further analysis, and the system includes a chemometric calibration model that relates geological attributes from analytical data previously obtained from at least two analytical techniques. A prediction engine applies the chemometric calibration model to the combined analytical information from the geological sample to predict specific geological attributes in the unknown geological sample.

1. A system for analyzing an unknown mineralogical sample, the system comprising:
at least two analytical subsystems including a near-infrared spectral-analysis subsystem to obtain molecular information about the mineralogical sample and at least one other analytical subsystem to obtain elemental information about the mineralogical sample, so each of the at least two analytical subsystems provides different information about the mineralogical sample; a data collection component to collect and combine the molecular information and elemental information from the analytical subsystems to create combined analytical information as a set of data vectors in a combined database; a chemometric calibration model that includes a set of vectors that relate mineralogical attributes to molecular and elemental information previously generated with at least two analytical systems that are the same types of systems as the at least two analytical subsystems; a prediction engine that multiplies the set of vectors in the chemometric calibration model by corresponding data vectors in the combined database to produce predictions of mineralogical attributes in the unknown mineralogical sample; and a display to display the predictions produced by the prediction engine.
