At the St. Johns Dome, Arizona, CO2 naturally occurs in the subsurface, but there are travertine rocks on the surface which are an expression of CO2 leakage to the surface. These travertine deposits occur along faults, zones where the rock layers are fractured and displaced. In our research, we use geomechanical analysis to show that the CO2 leakage occurs at points where the faults are likely to be permeable due to the orientation of the geological stress field in the subsurface.

Here we test conceptual models of fracture development by investigating fractures across multiple scales. We find that most fractures increase in abundance towards the fold hinge, and we interpret these as being fold related. Other fractures at the site show inconsistent orientations and are unrelated to fold formation. Our results show that predicting fracture patterns requires the consideration of multiple geologic variables.

Virtual field trips are used to engage students who are unable to go into the field with geological field work. Here, we investigate the perceptions of staff and students before and after a virtual field trip, including the investigation of the success of mitigation measures designed to decrease barriers to engagement and inclusion. We conclude that negative and positive perceptions exist and that effective mitigation measures can be used to improve the student experience.

Raman spectroscopy of carbon-bearing rocks is often used to calculate peak temperatures and therefore burial history. However, strain is known to affect Raman spectral parameters. We investigate a series of deformed rocks that have been subjected to varying degrees of strain and find that there is a consistent change in some parameters in the most strained rocks, while other parameters are not affected by strain. We apply temperature calculations and find that strain affects them differently.

Uncertainty is an inherent property of any model of the subsurface. We show how geological topology information – how different regions of rocks in the subsurface are connected – can be used to train uncertain geological models to reduce uncertainty. More widely, the method demonstrates the use of probabilistic machine learning (Bayesian inference) to train structural geological models on auxiliary geological knowledge that can be encoded in graph structures.

The potential for hydraulic fracturing (fracking) to induce seismicity is a topic of widespread interest. We find that terms used to describe induced seismicity are poorly defined and ambiguous and do not translate into everyday language. Such bad language has led to challenges in understanding, perceiving, and communicating risks around seismicity and fracking. Our findings and recommendations are relevant to other geoenergy topics that are potentially associated with induced seismicity.

Virtual outcrop models are increasingly used in geoscience teaching, but their efficacy as a training tool for 3D thinking has been little tested. We find that using a virtual outcrop increases the participants' ability to choose the correct geological block model. That virtual outcrops are viewed positively, but only in a blended learning environment and not as a replacement for fieldwork, and virtual outcrop use could improve equality, diversity and inclusivity in geoscience.

In this paper, we outline the key insights from decision-making research about how, when faced with uncertainty, humans constrain decisions through the use of heuristics (rules of thumb), making them vulnerable to systematic and suboptimal decision biases. We also review existing strategies to debias decision-making that have applicability in the geosciences, giving special attention to strategies that make use of information technology and artificial intelligence.

Seismic reflection data allow us to infer subsurface structures such as horizon and fault surfaces. The interpretation of this indirect data source is inherently uncertainty, and our work takes a first look at the scope of uncertainties involved in the interpretation of 3-D seismic data. We show how uncertainties of fault interpretations can be related to data quality and discuss the implications for the 3-D modeling of subsurface structures derived from 3-D seismic data.

The anisotropy of magnetic susceptibility (AMS) technique provides an effective way to interpret deforming mountain belts. In both the Betics, Spain, and Apennines, Italy, weak but well-organized AMS fabrics were recovered from young unconsolidated and unburied rocks that could not be analyzed with more traditional methods. Collectively, these studies demonstrate the novel ways that AMS can be combined with other data to resolve earthquake hazards in space and time.

This study focuses on the impact of major rift border faults on fluid circulation and hanging wall sediment diagenesis by investigating a well-exposed example in NE Greenland using field observations, U–Pb calcite dating, clumped isotope, and minor element analyses. We show that fault-proximal sediments became calcite cemented quickly after deposition to form a near-impermeable barrier along the fault, which has important implications for border fault zone evolution and reservoir assessments.

This paper presents a numerical method for restoring models of the subsurface to a previous state in their deformation history, acting as a numerical time machine for geological structures. The method relies on the assumption that rock layers can be modeled as highly viscous fluids. It shows promising results on simple setups, including models with faults and non-flat topography. While issues still remain, this could open a way to add more physics to reverse time structural modeling.

The aim of this paper is to describe, evaluate and develop a simple but robust low-cost method for capturing 2-D fracture network data in GIS and make them more accessible to a broader range of users in both academia and industry. We present a breakdown of the key steps in the methodology, which provides an understanding of how to avoid error and improve the accuracy of the final dataset. The 2-D digital method can be used to interpret traces of 2-D linear features on a wide variety of scales.

This paper reports a multiproxy approach to reconstruct the depth, timing, and extent of the past fluid flow during the formation of a fold-and-thrust belt in the Northern Apennines, Italy. The unique combination of paleopiezometry and absolute dating returns the absolute timing of the sequence of deformation. Combined with burial models, this leads to predict the expected temperatures for fluid, highlighting a limited hydrothermal fluid flow we relate to the large-scale subsurface geometry.

In carbonate rocks, fault zones influence the fluid flows and lead to important diagenetic processes modifying reservoir properties. The aim of this study is to identify the impact of two polyphase fault zones on fluid flows and reservoir properties during basin history. We determined petro-physic and diagenetic properties on 92 samples. This study highlights that fault zones acted as drains at their onset and induced fault zone cementation, which has strongly altered local reservoir properties.

Physical properties of layered sedimentary rocks affect nucleation and propagation of discontinuities therein. Fractures developing through sedimentary sequences characterized by the alternation of strong and weak layers are strongly deviated along their track at layers’ boundaries, and depending on the layer they cross-cut, they show very thick (strong layers) or very thin (weak layers) infills of precipitated minerals, potentially representing pathways for ore deposits and oil/water resources.

Short summary
When carbon dioxide is introduced into the subsurface it will migrate upwards and can encounter faults, which, depending on their hydrogeological properties and composition, can form barriers or pathways for the migrating fluid. We analyse uncertainties associated with these properties in order to better understand the implications for the retention of CO2 in the subsurface. We show that faults that form seals for other fluids may not be seals for CO2, which has implications for storage sites.
When carbon dioxide is introduced into the subsurface it will migrate upwards and can encounter...
