Geochemical characteristics of 36 Tertiary mudstone samples from Kuqa depression show that the content of CaO is very high, which can somewhat dilute other major elements, trace elements and rare elements. Some reliable indicators for provenance analysis show the source rock nature of noncarbonate sediments. The REE distribution pattern is similar to that of the upper continental crust, characterized by enrichment of LREE and negative Eu anomalies. Some trace element ratios show that the source rocks are mainly felsic.
