The Daqiaowu uranium deposit hosted in volcanic-intrusive rocks is located in the eastern Gan-Hang Tectonic Belt (GHTB). Currently, episodic volcanic eruptions in this area are still controversial, and the volcanic rocks have been lack of accurate geochronological data. Thus, this study focuses on zircon morphology and geochronology of volcanic rocks and their granitic breccias to elucidate the volcanism in Daqiaowu area. Morphological results obtained by scanning electronic microscopy indicate that zircon crystal types of volcanic rocks in the Huangjian Formation are mainly S24, S25, P3, P4 and P5. Typological statistics suggest that the magma of volcanoclastic rocks from the upper Huangjian formation is alkaline, while that from the upper Huangjian formation is calc-alkaline to alkaline. Zircon U-Pb dating suggests that the upper and lower Huangjian Formations were formed at 128 Ma and 133~135 Ma, respectively. These characteristics imply that they could be ascribed to different volcanic eruptions. The crystallization age of granitic breccias is 138 Ma, which represents the earliest magmatism in the Daqiaowu area, suggesting a possible basement of granitic intrusive body under volcanoclastic rocks. Based on the geochronology, petrography and drill cores, the volcanic eruption cycles in the Daqiaowu area can be divided into following stages: (1) the formation of a basement of granitic intrusive body (138 Ma); (2) Early stage of volcanic eruption (136 Ma), the Laocun Formation was formed with red conglomerate and volcanic sedimentary rocks; (3) intense volcanic eruption stage, this stage can be divided into two subcycles. The early subcycle, named the lower Huangjian Formation, was formed at 135 ~ 133 Ma and mainly composed of massive ignimbrite. The late subcycle, named the upper Huangjian Formation, was formed at 128 Ma and composed of greyish-white to greyish-green tuff and breccia-bering crystal tuff; (4) dike intrusion stage, granite and diabase dikes were formed during 128 ~ 125 Ma; (5) late eruption stage, shale, fine-grained sandstone, tuff and crystal tuff of the Shouchang Formation were formed at 123 Ma. Volcanic rocks along the GHTB were formed during the Early Cretaceous, and volcanic activities were more intense in the eastern part of GHTB than in the western part. In addition, Uranium-bearing volcanic sequences in the eastern part are younger than those in the western part, and mainly have ages of 135 ~ 127 Ma.
