The Liyuan gold deposit is hosted within Archean basement metamorphic rocks and controlled by the NNE-trending faults in the central North China Craton. The ore-forming processes can be divided into three stages (early, middle, and late). Three types of primary fluid inclusions (FIs) are identified in the Liyuan, including pure carbonic, carbonic-aqueous, and aqueous inclusions. The primary FIs of three stages are mainly homogenized at temperatures of 318-408 ∘ C, 201-329 ∘ C, and 136-229 ∘ C, with salinities of 2.1-8.9, 0.5-12.4, and 0.4-6.3 wt.% NaCl equivalent, respectively. The main Au mineralization is related to the middle stage, and water-rock interaction caused rapid precipitation of gold in this stage. The initial ore-forming fluids were likely magmatic water or metamorphic fluid and mixed with meteoric water at later stages. Due to the lack of granite body at the present mining levels, we speculate that it was magmatic water that might have been exsolved from a concealed granite body at greater depth or it was metamorphic fluid that was directly transported from depth via deep faults. Based on all the available geological and geochemical evidence, we suggest that the Liyuan deposit belongs to orogenic gold deposit that located in the interior North China Craton.

Early Precambrian tectonothermal events of the North China Craton: Constraints from in situ detrital zircon U-Pb, Hf and O isotopic compositions in Tietonggou Formation

et al. 2013

Clastic sediments and sedimentary rocks are widely used for understanding the formation and evolution of the continental crust. The Tietonggou Formation outcrops in the Xiaoqinling region at the southern margin of the North China Craton (NCC) and has unconformable contacts with the underlying Taihua Complex and overlying Paleoproterozoic Xiong'er Group. It mainly consists of quartzite and its protoliths are mature terrigenous clastic rocks. On the basis of the ages of the youngest detrital zircons from the quartzites and the ages of the Xiong'er Group, the depositional ages of the protoliths of the Tietonggou Formation were well constrained to 1.91-1.80 Ga. The U-Pb isotopic data of detrital zircons from the Formation show a major age peak at ~2.1 Ga, which is consistent with 2.2-2.0 Ga magmatism in the Trans-North China Orogen of the NCC. Taking into account the texctural and compositional maturity of the Tietonggou Formation quartzite, the ~2.1 Ga lithologic units in the Trans-North China Orogen are interpreted as the major source of the Tietonggou Formation. The majority of these ~2.1 Ga detrital zircons mostly have high δ 18 O values (>6.5‰) and negative ε Hf (t) values (-7.8-0.0), with corresponding Hf model ages significantly older than their crystallization ages, indicating that these zircons formed from the partial melting of ancient continental crust. The majority of the 2.8-2.7 Ga and ~2.5 Ga detrital zircons from the Tietonggou Formation had positive ε Hf (t) values, and mantle-like δ 18 O values, suggesting that the NCC has experienced two stages of significant crustal growth in the Neoarchaean at 2.7 and 2.5 Ga, respectively. The Hf isotopic data of detrital zircons from Paleoproterozoic metasedimentary rocks in the Trans-North China Orogen varied mainly toward the reduction of the radiogenic Hf isotope and gradually show a similar trend of the isotope trajectories of crustal evolution. This reveals that the NCC probably has not developed a long-lived subduction to complete the final assembly of the NCC. Alternatively, these maybe imply that the tectonic setting of the NCC substantially changed at ~2.1 Ga, the reduction of the radiogenic Hf isotope could be attributed to the rollback of the subducting slab.

“…According to the Nd and Hf isotopes, the best estimation age of mantle extraction of the North China Craton is 2.7 Ga Yang et al, 2009;Geng et al, 2012;Diwu et al, 2012;Ma et al, 2013;Wang et al, 2013), but the UPb ages in the North China Craton indicated that the strongest magmatic events occurred at ~2.5 Ga and the much of continental crust in the North China Craton has formed at that time (Liu et al, 1990;Zhao et al, 2002;Kröner et al, 2005;Yang et al, 2009;Wan et al, 2010Wan et al, , 2012aGeng et al, 2012;Diwu et al, 2012). The West Block of the North China Craton has formed with the collision between Yinshan and Erdos Blocks at 1.95~1.90 Ga Wan et al, 2006aWan et al, , 2010, and the united Western Block collided with the Eastern Block at ~1.85 Ga, (Wan et al, 2000(Wan et al, , 2006aZhao et al, 2000;Guan et al, 2002;Guo et al, 2005;Xia et al, 2006;Zhang, J. et al, 2006Zhang, J. et al, , 2007Zhang, J. et al, , 2009Zhang, J. et al, , 2012.

“…Because the fluvial sediment composition can reveal information about provenances of sediments, and zircons from fluvial sediments can be resistant to chemical weathering and mechanical abrasion, so they can survive weathering from their protoliths to river mouths where a single sample can provide information about the sources of an entire river basin (Rino et al, 2004;Wang et al, 2009;Yang et al, 2009). In the last decades, although extensive investigations have been carried out on the formation and evolution of the North China Craton, which led to discovery three Paleoproterozoic continent-continent collisional belts (Khondalite Belt, Trans-North China Orogen and Jiao-Liao-Ji Belt) (Wan et al, 2000(Wan et al, , 2006a(Wan et al, , 2012bZhao et al, 2000Zhao et al, , 2011Guan et al, 2002;Guo et al, 2005Guo et al, , 2012Xia et al, 2006;Zhang, J. et al, 2006Zhang, J. et al, , 2007Zhang, J. et al, , 2009Zhang, J. et al, , 2012Jian et al, 2012;Zhao and Guo, 2012), most of these investigations were focused on tectonic processes operative during the amalgamation of microcontinental blocks along these collisional belts, but few studies were concentrated on the accretion of the North China Craton, and especially on the accretion rates. Yang et al (2006) applied fluvial sediments to constrain the evolution of continental crust in China.…”

Growth rate of continental crust in the northeast margin of the North China Craton: Constraints from the U-Pb dating and Lu-Hf isotopes of detrital zircons from the Laoha River

et al. 2013

Recently, how to quantitatively estimate the growth rate of continental crust is an enigmatic issue. With the development of ICP-MS technology, the U-Pb dating and Lu-Hf isotopic compositions of detrital zircons from the fluvial sediments can provide an effective and simple approach to constrain the growth rate and evolutionary history of continental crust. In this paper, 189 concordant detrital zircons from the Laoha River have been analyzed for U-Pb ages and Lu-Hf isotopic compositions by excimer LA-MC-ICP-MS. Detrital zircons from samples LH and LH2 show three major age groups, i.e., 2370 Ma~2572 Ma, 1728~2087 Ma, 127~376 Ma and 2374~2598 Ma, 1765~2087 Ma, 119~405 Ma, respectively. They have the common prominent two stage Hf model ages with a peak at ca. 2.7 Ga, which is consistent with the global continental crust. These indicate that the timing of the strongest magmatic events is at ca. 2.5 Ga and 1.8 Ga, and the best estimation age of mantle extraction of the northeast margin of North China Craton is ca. 2.7 Ga. The detrital zircons with U-Pb ages of ~1.8 Ga and ~2.5 Ga have the two stage Hf model ages of ca. 2.7 Ga, whereas ε Hf (t) values are different from those of depleted mantle. These indicate that the majority of continental crust of the northeast margin of North China Craton at time of ~1.8 Ga originated from the reworking of ~2.7 Ga crust. About 5% of the present crustal volume in the northeast margin of North China Craton was formed at 2.9 Ga; whilst ~64% of the present crustal volume in the northeast margin of North China Craton has been formed at 2.5 Ga, which is higher than that of previous studies. It suggests that the continental crust growth in the North China Craton is not uniform, but it is consistent with the episodic growth of global continental crust (60%). Moreover, the majority continental crust of the northeast margin of North China Craton has been formed at 1.8 Ga (84%) as previously interpreted. Finally, we have used formulas to quantitatively calculate the reworking rate and give a suggestion that the time of 2.5 Ga is also the main growth period of continental crust of the North China Craton, and the time of 1.8 Ga is the strongest reworking period of the continental crust in the craton. In addition, the reworking rate began to drop after reactivating in the North China Craton, and the addition of depleted mantle was gradually increased.
