Summary: A doublet earthquake event occurred on 1 July 2022 in the Zagros fold-and-thrust belt in southeast Iran, involving two main shocks with a magnitude larger than M-w 6.0. The InSAR deformation field revealed significant surface uplift caused by fault-related folding in the seismic zone. The preferred faulting model suggests that higher dip angle and overlying gentle dipping faults were responsible for the two main shocks, with the first main shock triggering the second one.

Summary: Quantifying the kinematics of subaerial salt and understanding its correlation with geomorphic, tectonic, and climatic factors is crucial in exploring the interactions between Earth's spheres. This study integrated various datasets to explore the potential correlation between subaerial salt motions and geomorphic, tectonic, and climatic factors in the Kuqa fold-thrust belt (KFTB), NW China. The research revealed a maximum of 25 mm/yr vertical and 40 mm/yr horizontal surface salt deformation in the KFTB from 2014 to 2020, indicating a gravity spreading dominant system influenced by topography and weather variables.

Summary: The Kuqa fold-thrust belt in China is known for its diverse surface salt structures. By studying the geomorphological features of lateral ridge propagation along the belt, researchers have found evidence supporting the formation of the belt through a combination of detachment folding and source-fed thrust faults.

Summary: The Yinggehai Basin is a highly overpressured basin, where the seal capacity of caprocks is crucial for controlling the vertical distribution of oil and gas. The study found that both C1 and C2 caprocks in the diapir zone and only C2 caprock far from the diapir zone experienced hydraulic leakage, suggesting that diapirism played a role in promoting natural hydraulic fracturing.

Summary: Cadomian calc-alkaline and within-plate igneous rocks are widespread in the crust of Iran, and they are believed to have formed in a convergent margin associated with the subduction of oceanic lithosphere. These rocks are found in both unmetamorphosed magmatic form and metamorphic form, and they are associated with metasediments and terrigenous rocks. In addition, salt diapirs in the Zagros Fold-Thrust belt of Iran contain xenoliths of Cadomian igneous and sedimentary rocks, indicating their presence in a retro-arc rifted basin.

Summary: Iranian's karst bauxites, part of the Irano-Himalayan bauxite belt, are associated with the Zagros Fold-Thrust Belt (ZFTB) and exhibit different compositions reflecting varied paleoenvironmental conditions. The composition of ooidal concretions in the bauxites indicates periods of humid tropical climate followed by intermittent dry-to-wet conditions. Ce/Ce* distribution in the bauxites suggests paleoredox evolution during bauxitization, with different patterns observed in different deposits. The provenance proxies indicate a UCC-like protolith for the ZFTB bauxite deposits, derived primarily from bedrock argillaceous sediments.

Summary: This study presents a detailed geological map of the Les Avellanes salt Diapir in the South-Central Pyrenees. By analyzing structural, stratigraphical, and sedimentary data, the timing of the diapir emplacement was inferred. It was found that the salt extrusion occurred during the folding process of the mountain range.

Summary: The Zagros fold and thrust belt (ZFTB) in Iran serves as a natural laboratory for studying the kinematics of Arabia-Eurasia convergence/collision and has economic significance. This orogenic belt exhibits variations in stratigraphic makeup and structural style, as well as occurences of ophiolites along the Zagros suture line. The tectonostratigraphic attributes of the ZFTB are shaped by the irregular pre-collisional geometry at the northeastern edge of the Arabian Plate, as proposed in this paper.

Summary: The Zagros phosphogenic horizon, located in Iran, is an important and high-grade phosphatic resource formed along the Tethyan Realm over 50 million years. The paleoenvironmental conditions during its formation varied from oxic-suboxic to anoxic states in a shallow marine setting. The petrographic and geochemical studies provide insights into the evolution and depositional paleoenvironment of these phosphorites.

Summary: A regional sequence-stratigraphic framework is proposed for the Berriasian-Barremian shallow platform succession in the Zagros Fold-Thrust Belt, supported by biostratigraphic results and calibrated by Sr-isotope data. Four large-scale sequences and sixteen small-scale sequences were identified and described, representing different depositional environments and platform growth architectures in different stages of the Berriasian-Barremian succession.

Summary: The integration of biostratigraphy, strontium isotope stratigraphy, and magnetostratigraphy provided precise dating of sedimentary evolution in the Fars arc, revealing the migration of sedimentary belts and propagation of folding. High rates of folding propagation suggest an efficient detachment level at the base of the deformed Arabian sedimentary cover, influencing the deformation propagation within the cover sequence and understanding the in-sequence deformation of the Zagros Simply Folded Belt.

Summary: Cavernous weathering, characterized by honeycomb structures, is a common feature of both natural and artificial exposures. The most favored theory for the origin of honeycombs is salt weathering. In a study conducted in the coastal area of Tuscany, the evaporation pattern and salt deposition in honeycomb pits and lips were examined. The results showed that the evaporation rate and salt precipitates were higher in the pits than in the lips, supporting the theory of salt weathering. Surface tensile strength measurements indicated that case hardening does not protect the honeycomb lips.

Summary: The weathering/disintegration of sandstone is a complex process that can damage building stone. Disconnected portions are common in dry climates, often elongated parallel to horizontal surfaces. Physical experiments indicate that confinement by surrounding rock mass may delay the weathering process.

Summary: This study provides a deeper understanding of the factors controlling the composition and distribution of salt in the processes forming tafoni and honeycombs. The results show that salt composition is influenced by the chemical composition of rainwater and the lithology of the rocks. Gypsum is the major salt found in all sites, with halite dominating in arid sites. The salt content in tafoni varies between the backwalls and outer walls, with higher concentration in the backwalls in arid sites and no difference in humid sites.

Summary: This study describes five quartzose sandstone slabs containing Anaconularia anomala from the Letna Formation in the Prague Basin. The slabs contain adjacent conulariids and other fossils buried in a single bedding plane. The investigated conulariids show strong alignment and suggest burial by unidirectional currents. The growth pattern of the conulariids does not indicate clonal budding.

Summary: A study on evaporation from 10 lithologies reveals that the evaporation rate is influenced by vaporization plane depth, lithology, and climate seasonality. Vaporization plane depth plays a key role in determining the evaporation rate. This research has broad applications in various fields, including evaporation estimates and hydrologic balance, shallow rock hydrologic processes, living conditions of organisms, weathering processes, and cultural heritage protection.
