摘要
Based on the research of slices, the authors consider that there are authigenic rutile and strontianite in Changxing-Feixianguan Formation in the northeast area of Sichuan Province. This paper indicates that rutile and strontianite are generated respectively by the reactions between the geothermal hot water formed in middle-late diagenetic period and chlorite, carbonate rock in blackmica rich and between that and carbonate rock rich in strontium trough mineralogy theory and analyses including EMP, SEM and energy spectrum. Mass facts approve that the formation of rutile and strontianite is the result of trace elements redistribution in Changxing-Feixianguan Formation in the process of depositional diagenetic evolvement.
