“…These have been used as a broad representation of the continental crust for studying its age and composition, and from this, the patterns of continental growth and evolution (e.g. Wang et al 2009Wang et al , 2011Iizuka et al 2010Iizuka et al , 2013. In this paper, we review some of the major contributions that zircon studies have made to our understanding of the formation and evolution of continental crust.…”

The strong resilience of the mineral zircon and its ability to host a wealth of isotopic information make it the best deep-time archive of Earth's continental crust. Zircon is found in most felsic igneous rocks, can be precisely dated and can fingerprint magmatic sources; thus, it has been widely used to document the formation and evolution of continental crust, from pluton-to global-scale. Here, we present a review of major contributions that zircon studies have made in terms of understanding key questions involving the formation of the continents. These include the conditions of continent formation on early Earth, the onset of plate tectonics and subduction, the rate of crustal growth through time and the governing balance of continental addition v. continental loss, and the role of preservation bias in the zircon record.

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.

“…Furthermore, individual zircons can be analyzed for U-Pb isotopes to identify a specific sequence of major magmatic events, and their Lu-Hf and O isotopic compositions can provide information on continental crustal evolution. Detrital zircons therefore have offered useful information of the provenance of clastic sediments and sedimentary rocks, regional magmatic events and the evolution of the continental crust, such that they have recently become one of the hotspots in geological research [1][2][3][4]. This study investigated U-Pb geochronology and Hf-O iso-topic compositions of detrital zircons from the Paleoproterozoic Tietonggou Formation quartzite at the southern margin of the North China Craton (NCC) to constrain the compositions and possible sources of the sediments.…”

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.
