Abstract：The heavy minerals in sandstones in the burial diagenetic environment will suffer the solution and even form new heavy mineral cements. Provenance analysis method by using the characteristics of heavy minerals is one of the most important methods in the Upper Triassic Yanchang Formation of Ordos Basin. However,three kinds of heavy minerals, including garnet,sphene and epidote, have changed a lot during their diagenetic stage. Garnet was dissolved and become facet garnet,some was replaced by calcite,chlorite or quartz. The authigenic sphene crystals and sphene overgrowth were discovered,and sphene growth had several times. Authigenic epidote crystals and epidote overgrowths were seen,part of epidotes were replaced by chlorite or quartz. Garnet with relatively strong stability was dissolved,and detrital sphene and epidote with relative weak stability were not dissolved. This phenomenon is not consistent with knowledge of the heavy mineral stability in previous studies,and we hope it could be taken seriously by the researchers in the future.
