“…Jin, ; Wu, Zhang, Yang, Xie, & Yang, ; Zhu et al, ). The latest zircon data indicate that the North China craton potentially contains even a Hadean crust in its northeastern part (Z. Li, Chen, & Wei, ); however, no Neoproterozoic granitoids occur. In contrast, the South China block is characterized by dominantly Proterozoic crust, with minor components of Archean crust (Lei & Shu, ; H. L. Li et al, ; Su et al, ; Zhao et al, ).…”

The current state of knowledge on the early Paleozoic evolution of Japan is reviewed. Although early Paleozoic Japan marked the foundation of long‐lasting subduction‐related orogenic growth throughout the Phanerozoic, details of this have not been fully revealed. Nevertheless, U‐Pb dating of zircons both in Paleozoic granitoids and sandstones is revealing several new aspects of early Paleozoic Japan. The timing of the major tectonic change, from a passive continental margin setting (Stage I) to an active one (Stage II), was constrained to the Cambrian by identifying the oldest arc granitoid, high‐P/T blueschist, and terrigenous clastics of arc‐related basins. Ages of recycled zircons in granitoids and sandstones provided critical information on the homeland of Japan, i.e. the continental margin along which proto‐Japan began to grow. The early Paleozoic continental margin that hosted the development of an arc‐trench system in proto‐Japan had cratonic basement composed mostly of Proterozoic crust with a minor Archean component. The predominant occurrence of Neoproterozoic zircons in Paleozoic rocks, as xenocrysts in arc granitoids and also as detrital grains in terrigenous clastics, indicates that the relevant continental block was a part of South China, probably forming a northeastern segment of Greater South China (GSC) together with the Khanka/Jiamsi/Bureya mega‐block in Far East Asia. GSC was probably twice as large as the present conterminous South China on mainland Asia. Paleozoic Japan formed a segment of a mature arc‐trench system along the Pacific side of GSC, where the N–S‐trending Pacific‐rim orogenic belt (Nipponides) developed with an almost perpendicular relationship with the E–W‐trending Central Asian orogenic belt. The faunal characteristics of the Permian marine fauna in Japan, both with the Tethyan and Boreal elements, can be better explained than before in good accordance with the relative position of GSC with respect to the North China block during the late Paleozoic.

“…The active continental margin tectonic model, first proposed by Bai et al [33], posits that the LB and LNB represent two exotic blocks while the JLJB is an intervening island arc or back-arc basin. This viewpoint has been supported by various pieces of evidence, including: (1) studies of Paleoproterozoic Liao-Ji granites using geochronology and geochemistry, which revealed that the I-and A2-type ~2.2-2.0 Ga granites constituted a calc-alkaline series likely formed in the extensional tectonic setting of a continental arc [52,54,55,120] and/or back-arc basin [27,38,90,106,[121][122][123]; (2) the reinterpretation of previously regarded (meta-)mafic rocks, which were believed to be examples of bimodal magmatism, together with the meta-volcanic rocks and Liao-Ji granites, that were developed in a rift environment as typical island arc basalts formed in a back-arc tectonic setting [15,24,68,124]; and (3) newly obtained detrital zircon U-Pb ages, combined with previous studies [27,104], showing unimodal age peaks of ~2.5 Ga for the Langzishan Fm. and ~2.15 Ga for the Li'eryu Fm., and bimodal age peaks at ~2.51 Ga and ~2.17 Ga for the Gaojiayu and Dashiqiao formations, respectively.…”

“…In around 2.2-2.0 Ga, a back-arc basin was initially formed. Accompanied by lithospheric extension and mantle upwelling, the partial melting of ancient crustal material, together with minor contributions of juvenile mafic rocks, generated widespread A2-type granitoids in the JLJB [27,[54][55]90,[120][121][122][123]. During this time, a large volume of volcanic clastics (boron-bearing), and debris derived from the magmatic arc, were rapidly deposited, forming the Li'eryu Fm.…”

The Liaohe Group, which is a significant lithostratigraphic unit within the Paleoproterozoic Jiao-Liao-Ji Belt situated between the Longgang and Liaonan-Nangrim blocks, comprises the Langzishan, Li’eryu, Gaojiayu, Dashiqiao, and Gaixian formations, which are characterized mainly by a clastic-rich sequence with an interlayered bimodal-volcanic sequence, carbonate-rich sequence, and (meta-)pelite-rich sequence. Currently, the tectonic background and evolution of the Liaohe Group remain contentious. Based on the study of detrital zircon geochronology and the zircon trace element characteristics in the Langzishan and Li’eryu formations in the North Liaohe Group in the Lianshanguan area, NE China, this paper reveals the formations’ provenances, depositional ages, and relationships with Paleoproterozoic granitoids (the Liao-Ji granites). The present results, in conjunction with previous studies, indicate that the depositional age of the Langzishan Formation is 2136 Ma and that of the Li’eryu Formation is 1974 Ma. The provenances of the Langzishan Formation and the Li’eryu Formation are mainly characterized by Neoarchean-to-early-Paleoproterozoic basement rocks (~2.6–2.4 Ga) and the Liao-Ji granites (~2.2–2.0 Ga), respectively. Moreover, the coeval mafic and metasedimentary rocks of the Liaohe Group exhibit characteristics of an extensional environment, which is represented by the tectonic setting of a back-arc basin. Notably, the Upper Langzishan Formation records a prominent shift in sedimentary environment from a passive continental margin to an active continental margin. In terms of the tectonic evolution of the North Liaohe Group and the Jiao-Liao-Ji Belt, our proposed model suggests that the Archean basement rocks in the northern part of the continental block, along with a limited contribution from the Paleoproterozoic Liao-Ji granites, served as the primary sources for the Langzishan Formation. Subsequently, the rapid deposition of the Li’eryu Formation was influenced by intense magmatism and subsequent erosion of the subduction-related magmatic arc (the Liao-Ji granites) within a back-arc basin environment. Lastly, the deposition of clastic materials from the Longgang blocks and the Liao-Ji granites resulted in the formation of the Gaojiayu, Dashiqiao, and Gaixian formations.

“…The abundant occurrence of Hadean detrital zircon is limited in ca. 3.0-3.3 Ga sandstone and quartzose clastic rocks (Froude et al, 1983;Compston and Pidgeon, 1986;Wilde et al, 2001;Cavosie et al, 2007;Nebel et al, 2014;Valley et al, 2014;Nelson, 2002;Wyche et al, 2004;GSWA;2005;Wyche, 2007;Paquette et al, 2015;Byerly et al, 2018), even though many odd localities have been reported (Mojzsis and Harrison, 2002;Iizuka et al, 2006;Martel et al, 2008;Diwu et al, 2013;Nadeau et al, 2013;Cui et al, 2013;Xing et al, 2014;Li et al, 2016).…”

The size of continents is an essential parameter to understand the growth of the continental crust and the evolution of the solid Earth because it is subject to tectonism and mantle convection and affects the preservation of the crust. This article reviews the secular change in the size of continents on the early Earth, focusing on terrigenous clastic rocks, especially quartzose sandstones occurring on relatively large continents. The earliest continental crust in the Hadean or early Archean was produced with a width of ∼200–500 km, similar to modern oceanic island arcs along subduction zones or oceanic islands in hot spot regions by mantle plume heating. Through the collision and amalgamation of such primitive continental crusts, continental blocks over 500 km in width and length evolved and appeared by ca. 3.5 Ga. Through further amalgamation, during ca. 3.3–2.5 Ga, the Archean continents emerged with widths and lengths greater than 1,000 km, which were still smaller than those of modern continents. Continents with widths and lengths of nearly 10,000 km have existed since ca. 2.4 Ga (early Proterozoic). Further analyses of the composition and formation mechanism of clastic rocks will help reveal more quantitative secular changes in the sizes of continents.
