Summary: In this study, the relationship between lateral slip gradients and splay thrust faults on the Alaskan earthquake fault is investigated. The research shows that there is a lateral slip gradient along the fault line, which is caused by fault bends and splay faults, resulting in surface uplift. The study of the Denali fault in Alaska reveals the long-term coevolution of slip gradients and splay thrust faults.

Summary: The study focused on the crustal strength profile of the Kangding section of the Xianshuihe fault zone and identified three quartz deformation mechanisms during progressive deformation. It was found that the strength of the rock is weakened within the fault zone, which may lead to an increase in earthquake frequency.

Summary: This study analyzed the microstructure of a fault gouge from a low-angle normal fault in the European Alps, revealing a multistage history of deformation from ductile to brittle. The predominant deformation mechanism in the fault gouge was viscous-frictional behavior at the brittle-ductile transition, likely facilitated by phyllosilicates and graphite lubrication.

Summary: The study reveals that the activity of the Atotsugawa fault is related to highly connected fluid in localized ductile shear zones in the lower crust, while the conductivity anomalies in the lower crust may stem from fluid dehydration from the Philippine Sea slab and the Pacific slab.

Summary: A multidisciplinary approach to studying collisional orogenic belts in the Western Alps has revealed different foliations and cleavages developed at different metamorphic conditions during four tectonometamorphic phases, suggesting new tectonic implications for the exhumation of meta-ophiolites in this region.

Summary: This study focuses on the extrusion mechanism of the Sundaland block in the southeastern Tibetan Plateau. Through structural and kinematic analysis, timing of shearing, and thermal history reconstruction, the researchers reveal the tectonic processes driving the deformation of metamorphic complexes in the area. The study finds that Cenozoic dome structures are widely distributed, with high-grade metamorphic rocks in the cores and low-grade metamorphism and deformation in the mantles. Kinematic indicators and thermochronological data suggest that the formation and exhumation of the dome structures were associated with middle and lower crustal flow during the extrusion of the Sundaland block.

Summary: The Vinschgau Shear Zone (VSZ) is an important component of the Austroalpine domain, and its evolution during the Eo-Alpine Orogeny has been studied using detailed structural and petrochronological analyses. The fieldwork-based analyses indicate that the VSZ had a dip angle of 30-50 degrees and an E-W-trending stretching lineation. The shearing temperature was around 350-400 degrees Celsius. 40Ar/39Ar dating shows that the deformation of the VSZ occurred in the Late Cretaceous, with ages ranging from 80 to 97 million years.

Summary: This study investigates thermal water discharge within groundwater flow systems, showing that thermal water mixing with cold groundwater forms a thermal plume. By using models to calculate the geometry and flow rate of thermal water, the hidden discharge rates were estimated.

Summary: A reliable 3-D geophysical characterization of the deep tectonic structure in the Western Alps has been lacking. This study presents new receiver functions and S-wave velocity models to reveal a marked change in Moho attitude between the northern and southern regions, likely due to deformation of the slab during subduction. The subduction wedge is thicker and the mantle-wedge rocks are more involved in orogeny in the south, as evidenced by the presence of coesite in continental (U)HP rocks.

Summary: Structural analyses combined with new U-Pb zircon and titanite geochronology reveal the development and growth of two Early Cretaceous transpressional shear zones during oblique convergence. The two shear zones show contrasting patterns in terms of magma supply and structural relationship.

Summary: Variations in mantle sources and magmatic processes lead to significant changes in the crustal thickness and spreading pattern at mid-ocean ridges. Fast ridges have relatively uniform crustal thickness distributions, while slow and ultraslow ridges exhibit large lateral fluctuations and exhumation of mantle rocks. The spreading pattern changes from symmetric configuration to highly asymmetric plates accretion at slow ridges. This study uses numerical models to investigate the impact of mantle potential temperature and spreading rate on crustal thickness variations and tectonic patterns. The results show that the self-organization of magma supply, controlled by spreading rate and mantle potential temperature, plays a critical role in shaping the tectonic and crustal patterns of mid-ocean ridges.

Summary: Three large-scale ductile shear zones are distributed in the southeast margin of the Qinghai-Tibet Plateau, with the Gaoligong shear zone being less well studied. In this study, low-temperature thermochronological methods were used to investigate the exhumation history of the Gaoligong Mountain. The results reveal two stages of rapid exhumation events and differences in exhumation rates and timing along the mountain.

Summary: Studying the spatial pattern of slip rates along the Haiyuan fault zone reveals the deformation process along the northeastern margin of the Tibetan Plateau. The results suggest that the Madongshan and Liupanshan could be the main uplifts absorbing the left-lateral motion along the fault zone, while slip rates often vary at fault tips.

Summary: The study of drilling results from IODP Site U1518 reveals that the Papaku fault has a large offset and exhibits intense tectonic ductile deformation and asymmetric distribution of structures. The tectonic ductile deformation within the fault zone can be explained by seafloor overthrusting. Interstitial pore water geochemical profiles indicate the repetition of near-seafloor diagenetic sequences below the fault, suggesting recent overthrusting within the last 50-100 kyr. Therefore, the Papaku fault may define a low-permeability seal that maintains locally high pore fluid pressures and low fault strength, which could be favorable for the occurrence of slow slip events.

Summary: Dental enamel provides valuable information about an individual's early life, and isotopic and trace element ratios have been used to study dietary and weaning histories. This study analyzed the enamel of three Italian infants from the early twentieth century, and found that both Ca-isotopes and trace element ratios can provide insights into breastfeeding and formula feeding patterns. However, Ca-isotope data alone are not sufficient to distinguish between breastfed or formula-fed infants.
