Summary: The study examines extreme flood hazards on low-order streams in the arid eastern slope of the North Cascades, identifying different types of debris flow and flood systems based on morphometric variables and stratigraphic records to estimate recurrence intervals. It suggests a link between fires and debris flows at the landscape scale based on the aspect of the valley walls.

Summary: This study on a tonalite-trondhjemite-granodiorite (TTG)-granites-quartz monzonite assemblage in the northeastern North China Craton provides insights into the growth and evolution of the early continental crust. Geochemical and geochronological analysis reveals the residues of garnet-amphibolite-to-eclogite facies in the TTGs, indicating a continental arc setting for their formation. The involvement of various crustal materials from different geological eras suggests a complex crustal evolution process.

Summary: The late Archean is a crucial period when the properties of the continental crust changed significantly, and a shift in geodynamic processes occurred. The Neoarchean Suizhong granitic belt in the North China Craton is a natural laboratory for studying the evolution of the early Archean upper continental crust during the late Archean. The study reveals that the granitic belt mainly consists of K-rich granitoids, which are compositionally different from the early Archean upper continental crust dominated by TTGs. Collisional orogenesis played a critical role in maturing the Archean continental crust and initial cratonization of the NCC during the late Archean.

Summary: The Trans-North China Orogen (TNCO) is a major Paleoproterozoic collisional orogen within the North China Craton (NCC). A study of high-grade metamorphic rocks within the TNCO reveals key information about the growth of continental crust. The Hengshan Complex in the TNCO records two episodes of crustal growth at around 2.8-2.7 Ga and 2.1-2.0 Ga, reflecting the final cratonization of the NCC.

Summary: The discovery of ca. 2.7 Ga tonalite-trondhjemite-granodiorite (TTG) in the North China Craton (NCC) provides crucial evidence for understanding Neoarchean crustal evolution. This study presents new constraints on crustal growth and reworking during the Neoarchean through the mapping of ca. 2.7 Ga TTGs, associated ca. 2.6-2.5 Ga high-K granites and high-Mg diorites in the northern Qingyuan region of NCC. Zircon U-Pb dating reveals their formation ages and geochemical analyses suggest different origins for each lithology. Combined with previous studies, it is evident that the northeastern NCC experienced two major periods of crustal growth and reworking around ca. 2.7 Ga and ca. 2.6-2.5 Ga.

Summary: The Huai'an Complex in the North China Craton consists of TTG gneisses and granite intrusive bodies. Zircon U-Pb ages reveal three episodes of magmatism from 2.6-2.3 Ga, 2.0-1.7 Ga, and similar ages around 2.3-2.0 Ga, indicating different magma sources. The complex underwent crustal growth and reworking stages from 3.1-2.5 Ga to 1.95-1.7 Ga, with tectonic processes of compression-extension-compression during 2.6-1.7 Ga.

Summary: This study investigates the Chengde Complex in the North China Craton, which is a typical Precambrian collisional orogen, and reveals that it is composed of rocks with different metamorphic grades and ages. The unordered juxtaposition of diverse metamorphism could also be a typical feature of Precambrian orogens.

Summary: This study reconstructed the fire and vegetation history at a mid-elevation mixed-conifer site in the eastern Cascades, and found that a mixed-severity fire regime has existed at the site for the past approximate 6000 years, with fire episodes occurring on average every 80-100 years. Additionally, only one fire episode occurred in the past 500 years, and none within the past 150 years. Compared to other eastern Cascade sites, the fire regimes at Long Lake during the late Holocene appeared to be intermediate between those observed at higher- and lower elevation sites in terms of fire severity and frequency.

Summary: The formation and tectonothermal overprinting of the Meso-Neoarchean metagranitoids in the Wuhe complex of the southeastern margin of the North China Craton are not well understood. Understanding the Phanerozoic overprinting in Archean complexes is important for comprehending the evolution of the North China Craton. The rocks in the Wuhe complex were affected by multiple tectono-magmatic-metamorphic thermal events, and the presence of inherited zircons suggests the underthrusting of the Yangtze Craton beneath the North China Craton during the Triassic.

Summary: The study presents a detailed analysis of the formation of the Kuna Crest lobe in the Tuolumne Intrusive Complex. By examining the lithologies, structures, and chemical compositions of the rocks, the study reveals the establishment of a pre-heated pathway and the formation of a magma mush zone that allowed for magma mixing and crystal-liquid separation.

Summary: A study of the Dengfeng complex in the Jishan area reveals the evolution of the Neoarchean continental crust in the southern margin of the North China Craton. The results show that the supracrustal assemblage in the Dengfeng complex mainly originated from the accretive basement material of the southern NCC, while the plutonic intrusions formed in the Late Neoarchean through partial melting of the accretive lower crust. The study also suggests a large-scale continental crust growth in the southern margin of NCC at around 2.7 Ga.

Summary: This study investigates the properties of magmas that can stabilize orthopyroxene in igneous charnockites. Petrologic analyses and thermodynamic constraints are performed on high-maficity and peraluminous charnockites from the Jining Complex in the North China Craton. The results show that these charnockites have ultrahigh temperatures, low H2O contents, and limited aluminum saturation indexes, and they are generated by partial melting of a greywackic granulite source.

Summary: This study investigates the tectonic evolution of the South Qilian Ocean in the North Qaidam tectonic belt through analyzing two groups of intermediate-mafic rocks. The results reveal the crucial roles of decompression melting and heat flow in the generation of magmas during the transition from oceanic subduction to continental subduction.

Summary: In this study, a comparative and integrative analysis of seismic tomographic models, teleseismic receiver function results, and Airy isostasy was conducted to investigate the properties of the lower continental crust in eastern North America. The analysis revealed three key features: deepened Vs depth contours and strong negative Airy misfit in the U.S. Grenville Province, faster-than-average and denser-than-average lowermost crust in the eastern North American Craton and the Grenville Province, and thickest, fastest, and densest lowermost crust beneath specific tectonic boundaries. This study provides new constraints on the seismic and compositional properties of the lower crust in eastern North America.
