Special Issue Information

Dear Colleagues,

The North China Craton (NCC) is a Precambrian stable block surrounded by the Central Asian Orogenic Belt and the Qilian–Qinling–Dabie Orogenic Belt. It preserves extremely ancient rocks on the Earth’s surface and serves as a unique natural site and field laboratory for understanding the Earth’s early history and studying early crustal evolution.

Intermediate to high-grade metamorphosed supracrustal rocks form at deeper levels of the lithosphere and can record multiple episodes of tectonic-thermal events, serving as a geological “video recorder” of these processes. Igneous intrusions, such as the tonalite–trondhjemite–granodiorite (TTG) suite, are also a widespread and voluminous constituent of Archaean cratons, which were commonly metamorphosed and can offer us opportunities to investigate the crustal evolution of the old terranes. Therefore, these old rocks that formed in the NCC are ideal objects for investigating crustal formation and evolution, geodynamic processes, and particularly tectono-thermal evolution during the Precambrian period.

In recent decades, the formation and evolution of the Precambrian basement in the NCC have garnered widespread attention from the international geological community, and significant progress has been made in various aspects. This Special Issue aims to present contributions and the latest advancements related to Precambrian rocks within and around the NCC, including but not limited to geochronology, geochemistry, and isotopic studies; pressure–temperature (P-T) paths of metamorphic rocks; and crustal growth and reworking events, among others.

The Anshan–Benxi area, situated in the northeast of the North China Craton (NCC), is home to not only the oldest rocks in China (~3.8 Ga) but also a diverse range of granitoids dated between 3.8 and 2.5 Ga. The Lianshanguan batholith, covering an [...] Read more.
The Anshan–Benxi area, situated in the northeast of the North China Craton (NCC), is home to not only the oldest rocks in China (~3.8 Ga) but also a diverse range of granitoids dated between 3.8 and 2.5 Ga. The Lianshanguan batholith, covering an area of approximately 250 km2 with an east–west trend, predominantly consists of syenogranites (K2O > 4 wt. % and K2O/Na2O ratios > 1.3). Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) U-Pb analyses of the two syenogranites yielded concordant ages of 2541 ± 22 and 2512 ± 13 Ma, respectively. These syenogranites had zircon εHf(t) values ranging from −20 to +4.9 with two-stage Hf model ages (TDM2(Hf)) spanning 3.9–2.7 Ga. Based on petrological, geochemical, and isotopic characteristics, we conclude that the Lianshanguan syenogranites are mainly resulted from the reworking of complicated Eoarchean–Mesoarchean crustal materials, possibly with a small proportion of ~2.7 Ga juvenile crustal materials. When compared with coeval syenogranites from the Northern Liaoning and Western Liaoning–Eastern Hebei areas, ~2.5 Ga syenogranites from the Anshan–Benxi area displayed more complicated TDM2(Hf) ages, hinting at a pronounced late Neoarchean reworking of the Eoarchean to Mesoarchean continental crust (including metasedimentary sources) primarily in the Anshan–Benxi region of the North China Craton. This scenario significantly bolsters the arc–continent collision model. Full article
