“…Once naturally precipitated, it has low stability and a tendency toward recrystallization; the morphology is easily modified (Lippmann, 1973;Rodriguez-Navarro et al, 2007). Dawsonite is a common authigenic mineral that can have an acicular shape, more elongated than classes A and B; usu-ally it forms in the eodiagenesis of continental alkaline saline environments, when pore water is concentrated in Al, or in mesodiagenetic CO 2 storage environments (Eugster, 1980;Hellevang et al, 2013;Xia et al, 2022). However, Al was detected inside and outside the dubiofossils.…”

Abstract. Minerals are the fundamental record of abiotic processes over time, while biominerals are one of the most common records of life due to their easy preservation and abundance. However, distinguishing between biominerals and abiotic minerals is challenging due to the superimposition and repetition of geologic processes and the interference of ubiquitous and diverse life on Earth's surface and crust. Mineral dubiofossils, being potential outcomes of both abiotic and biotic environments, emerge as valuable entities that can contribute significantly to the understanding of this issue, facilitating the testing and refinement of biogenicity criteria. The aim of this contribution is to decipher the origin and history of branched mineralized structures that were previously considered mineral dubiofossils from the Pennsylvanian of the Paraná Basin, Brazil. While this material has different forms and refers to biological aspects, it is challenging to associate it with any known fossil group due to the overlapping geological processes occurring in a transitional deposit of Rio do Sul Formation (Itararé Group of the Paraná Basin), particularly in close proximity to a sill from the Serra Geral Group (Lower Cretaceous), which has undergone thermal effects. Given the absence of attributes essential for supporting the initial hypotheses proposing the material as a potential set of sponge spicules or a result of contact metamorphism in Pennsylvanian turbidites, the objects are now investigated as mineral dubiofossils. To address this challenge, we have developed a descriptive protocol for dubiofossils, building upon prior research in the field. This protocol evaluates the following aspects: (1) morphology, texture, and structure; (2) relationship with the matrix; (3) composition; and (4) context. This is done by assessing indigeneity and syngenicity and comparing the specimens with abiotic and biotic products. Applying this protocol to our samples revealed a wide range of morphologies with internal organization, predominantly composed of calcite with impurities such as iron, magnesium, aluminum, and oxygen. The inferred indigeneity suggests the presence of these minerals concurrently with or prior to the intrusion of the sill. Extensive comparisons were made between the studied samples and a broad spectrum of abiotic minerals, as well as controlled, induced, and influenced biominerals from similar contexts. These comparative analyses encompassed sponge spicules; sea urchin and algae skeletons; minerals induced or influenced by fungi, bacteria, and microbial mats; and inorganic pre- and synsedimentary–eodiagenetic minerals like evaporites, springs, and other precipitates, and mesodiagenetic–metamorphic crystals. Despite this comprehensive analysis, no hypothesis emerged as significantly more likely than others. The comparative analysis did allow us to exclude the possibility of the samples being controlled biominerals due to their patternless diversity of morphologies, as well as purely thermometamorphic in origin due to their branched elongated forms. The occurrence of these structures suggests a complex history: a syn-depositional or eodiagenetic origin of some carbonate or sulfate (gypsum, ikaite, dolomite, calcite, aragonite, siderite), potentially associated with the presence of microbial mats, which may have served as templates for mineralization and mediated mineral growth. Mesodiagenesis could have further modified the occurrence through processes such as mineral stabilization, agglutination, aging, and growth. However, the primary agent responsible for the formation of the dubiofossil was the Cretaceous intrusion, which dissolved and replaced the initial minerals, resulting in the precipitation of calcite. Throughout these steps, a combination of physical–chemical and biological reactions, influenced by intrinsic matrix characteristics, organic matter content, and distance from the intrusive body, may have contributed to the heightened morphological complexity observed, thus corroborating the origin of the material becomes even more challenging. Consequently, both the hypotheses pertaining to the formation of biotic and abiotic sulfates and carbonates remain plausible explanations, hence sustaining the classification of the material as a dubiofossil. This material illustrates how dubiofossils can be a result of a complex history and overlapping geological processes. It also highlights the difficulty in differentiating biominerals from abiotic minerals due to the scarcity of biogenicity arguments.

“…Mantle-derived CO 2 occurrences have been well documented in different geological contexts around the world by various researchers (Lowenstern, 2001;Chiodini et al, 2004;Bigi et al, 2014;Hutchison et al, 2015;Lee et al, 2016;Lee et al, 2019;Yang et al, 2021;Hill et al, 2022;Xia et al, 2022). In the Songliao Basin (China), Liu et al (2018) reported that CO 2 mainly comes from deep magma, and accumulates mostly in the mantle uplift areas with the development of basement faults or strong deep hydrothermal activity.…”

“…Della Porta (2015) showed that in Central Italy, fault activity affects the development of hydrologically closed lacustrine basins, groundwater flow, and the location of hydrothermal vents, and classified their deposits as thermogenic travertines with thermally generated CO 2 of magmatic mantle-derived origin. Xia et al (2022) stated that, typically, significant quantities of CO 2 originate from three sources in the subsurface: organic matter maturation, magma degassing, and decomposition of carbonate minerals. Santos Neto et al (2012) interpreted that up to 80% of CO 2 anomalies in the Santos Basin are mantle-derived due to the isotope range of δ 13 C CO2 being mostly within −7‰ and −5‰ and the relatively high values for 3 He/ 4 He, represented by an R/Ra rate of up to 5.60.…”

We present a multi-scale conceptual model based on structural controls of the migration of mantle-derived CO2 offshore in the Santos Basin (Southeastern Brazil). We assembled the model from a regional 2D seismic reflection line integrated with potential gravimetric field data and a local 3D seismic reflection volume integrated with well data (lithologies and in situ stress). (i) The geochemical isotope range of δ13CCO2 falls mostly within −7‰ and −5‰ and shows relatively high values for 3He/4He represented by an R/Ra rate of up to 5.60, indicating CO2 mantle generation and degassing. (ii) Seismic interpretation feasibly validated by potential gravimetric responses of the crustal structure (Moho discontinuity) show CO2 migration through deep-seated faults in a region of highly stretched continental crust with oceanward mantle uprising. (iii) Early Cretaceous basement highs generated in an obliquely syn-rift faulting system control CO2 accumulation in thermogenic travertines (hydrothermal carbonate reservoirs of continental lakes), and Aptian evaporites subsequently trap it.

“…The fault cuts across the entire NCC and seismic velocity structure indicates that it is rooted in the mantle (Luo & Yao, 2021). Increasing mantle helium and carbon dioxide in the natural gas inside the Mesozoic basins from far to near the Tanlu fault also indicates a mantle embedded feature of the fault (Xia et al, 2022). Recent earthquakes, including the Tancheng earthquake of 1,668 (M8.5) (Wang, Jiang, et al, 2022), the largest one ever recorded in eastern China, ruptured along the Tanlu fault and indicate its active state even at present.…”

Large-scale strike-slip faulting commonly occurs in active tectonic margins, but rarely, if ever, do large faults cut deep into ancient continental nuclei known as cratons. With thick mantle roots, cratons are considered to be the most tectonically stable portions of Earth's continental lithosphere, with an eminent exception being the relatively recent destruction of North China craton. Here, we show that from 240 to 165 Ma ago the roughly coeval continental collisions of South China to the south and Mongolia to the north ruptured the Tanlu fault within the then thick North China craton. A large ~450 km displacement mechanically induced by a ~16° intracratonic rotation along the Tanlu fault reconciles the offsets of geological piercing points and palaeomagnetic data of North China on either side of the fault. Shortly after the displacement of the only large young strike-slip cratonic fault, the cratonic lithosphere of eastern North China collapsed.
