HRTEM and Its Application to the Study of Reaction Mechanism in Polysomatic Reaction
نویسنده
چکیده
Kinetics and reaction mechanisms in polysomatic reactions of biopyriboles were reviewed in relation to mineralogical usage of HRTEM. HRTEM studies clarified the reaction mechanism and the polymerizing process from pyriboles to talc structure. Many zipper termination channels as reaction front were observed by tracing back from the obtained I-beam structure images. Another tunnel-like structures were found e.g. in the specimens of oxyhornblende, which may correspond to mass transfer tunnel in decomposition processes to form oxyhornblende. Such channels that play an important role in reaction process may be present in varieties of rock forming minerals. HRTEM method may become a kind of powerful tool to disclose such reaction mechanisms and reaction processes.
