Method and apparatus are provided for analyzing closely adjacent minerals in specimens of naturally occuring minerals. A sectioned mineral sample is mounted on a glass slide and placed in a vacuum chamber. An optical microscope is used to examine the sample through a window in the vacuum chamber. A laser beam is used for pyrolyzing a portion of the specimen causing gases to be released. Gases released from the mineral are analyzed by a mass spectrometer. Relative movement of the sample and laser beam, pyrolysis of target samples, and analysis of released gases can be automated.
