“…From the Eocene to the Miocene, the westernmost extension of the Ören–Afyon Zone (Ören Unit) was transported southward over the uplifting Menderes Massif (Güngör & Erdoğan, ; Rimmelé et al ., , ; van Hinsbergen et al ., ; Pourteau et al ., ). Former evaporite relicts within the pelagic carbonate formations are distributed widely in the Anatolide–Tauride Block (Scheffler et al ., ). The present study focuses on the neritic to pelagic carbonate sequence (the ‘Rosetta Marble’) of the Ören Unit, which crops out near the villages of Fesleğen, Akçakaya and Karaböğürtlen (Fig.…”

“…Meta‐evaporites and related meta‐sedimentary rocks, now present as marble fabrics and cherts, are regionally referred to as ‘Rosetta Marble’, a casual catch‐all term that is applied throughout this paper. Previous studies (Scheffler et al ., , ) established the fundamental stratigraphic distribution, lithological associations, primary versus metamorphic mineralogies, and metamorphic pressure–temperature ( P–T ) evolution of the Rosetta Marble deposits and the reader is referred to these sources for details.…”

Ancient evaporite deposits are geological archives of depositional environments characterized by a long-term negative precipitation balance and bear evidence for global ocean element mass balance calculations. Here, Cretaceous selenite pseudomorphs from western Anatolia ('Rosetta Marble')characterized by their exceptional morphological preservationand their 'marine' geochemical signatures are described and interpreted in a process-oriented context. These rocks recorded Late Cretaceous high-pressure/low-temperature, subductionrelated metamorphism with peak conditions of 1Á0 to 1Á2 GPa and 300 to 400°C. Metre-scale, rock-forming radiating rods, now present as fibrous calcite marble, clearly point to selenitic gypsum as the precursor mineral. Stratigraphic successions are recorded along a reconstructed proximal to distal transect. The cyclical alternation of selenite beds and radiolarian ribbon-bedded cherts in the distal portions are interpreted as a two type of seawater system. During arid intervals, shallow marine brines cascaded downward into basinal settings and induced precipitation. During more humid times, upwelling-induced radiolarian blooms caused the deposition of radiolarite facies. Interestingly, there is no comparable depositional setting known from the Cenozoic world. Meta-selenite geochemical data (d 13 C, d 18 O and 87 Sr/ 86 Sr) plot within the range of reconstructed middle Cretaceous seawater signatures. Possible sources for the 13 C-enriched (mean 2Á2&) values include methanogenesis, gas hydrates and cold seep fluid exhalation. Spatially resolved component-specific analysis of a rock slab displays isotopic variances between meta-selenite crystals (mean d 13 C 2Á2&) and host matrix (mean d 13 C 1Á3&). The Cretaceous evaporite-pseudomorphs of Anatolia represent a basin wide event coeval with the Aptian evaporites of the Proto-Atlantic and the pseudomorphs share many attributes, including lateral distribution of 600 km and stratigraphic thickness of 1Á5 to 2Á0 km, with the evaporites formed during the younger Messinian salinity crisis. The Rosetta Marble of Anatolia may represent the best-preserved selenite pseudomorphs worldwide and have a clear potential to act as a template for the study of meta-selenite in deep time. 2627

Acoustic emission (AE) signals contain substantial information about the internal fracture characteristics of rocks and are useful for revealing the laws governing the release of energy stored therein. Reported here is the evolution of rock failure with different master crack types as investigated using Brazilian splitting tests (BSTs), direct shear tests (DSTs), and uniaxial compression tests (UCTs). The AE parameters and typical modes of each fracture type were obtained, and the energy release characteristics of each fracture mechanism were discussed. From the observed changes in the AE parameters, the rock fracture process exhibits characteristics of staged intensification. The scale and energy level of crack activity in the BSTs were significantly lower than those in the DSTs and UCTs. The proportion of tensile cracks in the BSTs was 65%–75%, while the proportions of shear cracks in the DSTs and UCTs were 75%–85% and 70%–75%, respectively. During the rock loading process under different conditions, failure was accompanied by an increased number of shear cracks. The amplitude, duration, and rise time of the AE signal from rock failure were larger when the failure was dominated by shear cracks rather than tensile ones, and most of the medium- and high-energy signals had medium to low frequencies. After calculating the proposed energy amplitude ratio, the energy release of shear cracks was found to exceed that of tensile cracks at the same fracture scale.
