Objective

The sedimentary Zhaojiazhuang Formation overlies the ancient Paleo-proterozoic crystalline basement in the

middle–south sections of the Taihang Mountains, China. It is a complete stratigraphic sequence with clear

boundaries. The formation has an angular unconformity with the underlying Paleo-proterozoic Tongyu

Formation and a parallel unconformity with the overlying Changzhougou Formation from the Changcheng

System, which is widely distributed throughout the Wutai–Zhongtiao–Taihang Mountains. Qiu Zhen et al.

(2007) and Wang Qingchun et al. (2017) have examined its lithologic features, stratigraphic sequences,

sedimentary characteristics, and trace fossils of this formation. Studies have placed the Zhaojiazhuang

Formation in the Meso-proterozoic Changchengian compared with the Baicaoping Formation from the

Changcheng System in the Xiong’er rift trough. Till now, the ages of detrital zircons from the Zhaojiazhuang

Formation have not been reported. This study aims to provide new geochronological data for further

determining the contact relation between the Changcheng System and underlying Paleo-proterozoic via detrital

zircon U-Pb geochronology of the fine-grain quartz siltstone in the Zhaojiazhuang Formation.

Methods

Detrital zircon samples were taken from the off-white, thinly bedded fine-grain quartz siltstone in the third

layer of the lower Zhaojiazhuang Formation along the Licheng profile in the middle-south sections of the

Taihang Moutains. Zircon sorting was conducted at the rock and mineral analysis laboratory at the Research

Institute of Regional Geological and Mineral Resources, Langfang, Hebei Province. Zircons were selected via

water elutriation, high magnetic separation, and electromagnetic and heavy liquid separation. Then, the selected

large, fully-formed zircon grains were observed under stereomicroscopy. Zircons were mounted onto thin

sections with epoxy; then, the samples were grinded and polished sufficiently. Transmitted light, reflected light,

and cathodoluminescence images were taken to observe the surface and internal zircon structure.

Zircon LA-ICP-MS U-Pb dating was performed on an Agilent ICP-MS (Agilent 7900) at the isotopic

laboratory within Wuhan Sample Solution Analytical Technology Co., Ltd., and the detailed analytical

procedures were followed as reported previously (Duan Shigang et al., 2017). The original data were processed

using the ICPMSDATACAL 10 software, and zircon age concordia diagrams were constructed using the

ISOPLOT 3.0 program. For zircons older than 1000 Ma, the 207

Pb/206

Pb age was used, whereas for zircons less

than 1000 Ma, the 206

Pb/238

U age was used.

Results

We separated 286 zircons from the siltstone sample, LC-ZJZ. The zircon grains vary in size: the majority of

these were ellipsoidal, followed by short prismatic, a few were spherical, and there were occasional hexagonal

dipyramidal zircons, with particle sizes varying between 50 and 130 μm and several sizes >150μm. Zircon

shapes are mostly semicircular and sub-angular. Majority of magmatic zircons have oscillatory zoned structures,

whereas there are very few metamorphic zircons with internal uniformity and patch-like structures. In this study,

we obtained a total of 106 isotope data points and only one concordance data point was <90%. Zircon U-Pb

concordia diagrams and zircon age distribution histogram analyses were performed on the remaining 105 data

points (Appendix 1). The zircon Th/U ratio ranged from 0.03 to 1.49, where 94% of the data were >0.4,

indicating a mainly detrital magmatic origin for the zircons. The zircon 207

Pb/206

Pb age data ranged from

1758–2983 Ma, with a prominent main peak at 2517 Ma and three secondary peak ages of 1866, 2204, and

2687 Ma (Fig. 1). The youngest detrital zircon was 1758±55.7 Ma, and only two detrital zircons were older

than 2.8 Ga.

Conclusions

(1) The minimum concordant age of detrital zircon in the Zhaojiazhuang Formation is 1758±55.7 Ma (the

concordance is 98%), the time limit of deposition is after 1758±55.7 Ma. By comparing the Mesoproterozoic

age composition of the zircon ages in the northern margin, Xionger and Yanliao rift trough of the North China

Craton, the detrital zircon age composition was found to be in accordance with the zircon age composition of

Early Changcheng System, while it was very different from the zircon age composition in the newer strata;

therefore, we identify the Zhaojiazhuang Formation as an Early Changcheng System in the Meso-proterozoic.

(2) The peaks and composition of each age correspond to major Neo-archean and Paleo-proterozoic

geological events in the North China Craton. Zircon ages from 2.76–2.70 Ga, approximately 2.5 Ga (main

peak), and 2.45–1.95 Ga (secondary peak 1866 Ma) correspond to peak late Archean crustal growth in North

China Craton, the late Archean Cratonization event, the Paleo-proterozoic intracontinental tensile-rifting event,

and Paleo-proterozoic compressional tectonic events.

(3) Late Archean (approximately 2.5 Ga) North China Craton continental crust material is the main

provenance area, and meta-basic volcanic rocks and rocks from the Paleo-proterozoic Hutuo System in the

Lvliang–Wutai–Taihang area are the secondary provenance areas.
