1. A system for analyzing an unknown geological sample, the system comprising: at least two analytical subsystems including a near-infrared spectral-analysis subsystem and at least one other analytical subsystem, each of the at least two analytical subsystems providing different information about the geological sample; a data collection component to collect and combine the different information from each analytical subsystem to create combined analytical information; a chemometric calibration database that includes records that relate geological attributes to data previously generated with at least two analytical systems that are the same types of systems as the at least two analytical subsystems; and a prediction engine that applies the records in the chemometric calibration database to the combined analytical information to identify specific geological attributes in the unknown geological sample.
