“…The two laboratory-made rock specimens were prepared by mechanical compaction of brine-saturated mineral aggregates to 50 MPa effective vertical stress. The details of sample preparation for experimental mechanical compaction are presented in our previous studies. , The first laboratory-made specimen is composed of 50% carbonate (mainly calcite), 30% quartz, 10% kaolinite, and 10% smectite. The rock-forming minerals for the second laboratory-made sample are 50% carbonate (mainly calcite) and 50% reconstituted aggregates of organic-rich shale of the Kimmeridgian Draupne Formation.…”

Investigating fracture evolutions triggered by chemical interactions in caprocks of CO2 storage sites is of great importance when caprock integrity is concerned. Mineral heterogeneity is one of the factors affecting fracture evolution. We present results from flow-through experiments deploying a unique high pressure geo-material microfluidic cell to monitor the fracture evolution of four carbonate-rich caprocks: (1) a homogeneous carbonate-rich sample, (2) a heterogeneous carbonate-rich sample, (3) a heterogeneous carbonate-rich shale sample, and (4) a heterogeneous carbonate-rich organic shale sample, representing different levels of mineral heterogeneity. The results show rather smooth fracture wall dissolution for the homogeneous rock sample. For the heterogeneous sample without shale, however, an altered layer is formed around the fracture that leads to an increase in the fracture roughness. Chemical analyses of effluent solutions demonstrate a decrease in the bulk dissolution rate of calcite over time at a constant flow rate. For the two carbonate-rich shale samples, visual observations using optical microscopy showed little changes in fracture dissolution, although analysis of effluent chemistry confirmed calcite dissolution.

“…These values are comparable to our measured values from ash tuffs and pumices (Figures 1b, 2b). The surface breccia deposit from phase I has a silt-rich matrix, supporting sub-rounded to angular lapilli and blocks (Montanaro et al, 2020), and is likely very similar to the crater fill at shallow depth and pressure (Heap et al, 2015;Nooraiepour et al, 2019). Slightly cohesive silt/sand-rich samples from the phase I matrix (pIm), which were taken as representative source lithology for phase II eruption, have a bulk density of 1.6 g/cm 3 and 26.6% porosity.…”

“…As a first‐order approximation, we can quantify the explosive energy partitioning between reservoir rock fragmentation (or disaggregation) and ejection (kinetic) energies, assuming that: (i) no additional mass/energy was supplied from magma (Germanovich & Lowell, 1995); (ii) that there are no explosivity‐enhancing gases (e.g. CO 2 ; Hurwitz et al., 2016; Thiéry et al., 2010) within hydrothermal fluids; and iii) no temporary compaction affected shallow (<100 m) and friable host materials (Dasgupta & Mukherjee, 2020; Heap et al., 2015; Nooraiepour et al., 2019).…”

Steam-driven, phreatic and hydrothermal eruptions are a common explosive phenomenon in volcanic and geothermal systems (Browne & Lawless, 2001; Stix & Moor, 2018). In active volcanic terrains, phreatic eruptions may be triggered by the sudden arrival of extra fluid (gas, waters or brines) interacting with heat from intruding magma (Browne & Lawless, 2001; Stix & Moor, 2018). In geothermal settings, hydrothermal eruptions may be triggered by depressurization and steam-flashing of trapped hot pressurized fluids, released by earthquakes, landslides, or other localized natural hydrological disturbances (Browne & Lawless, 2001; Mastin, 1995; Thiéry & Mercury, 2009). Moreover, in both active volcanic and geothermal settings, hydrothermal alteration and mineral sealing can promote high local overpressures and thus more readily an explosive destabilization (Mayer et al, 2015, 2016; Scolamacchia & Cronin, 2016). Irrespective of the presence of shallow magma, flashed water contains enough energy to efficiently fragment rock and violently eject material upwards and laterally (Montanaro et al., 2016a; Morgan et al., 2009). Often impulsive and shortlived relative to magmatic eruptions, they are still deadly due to their sudden onsets, and the generation of violent blasts (

“…Semi-diagenesis rock, formed mainly in the Tertiary, is a kind of partly cemented sediment rock that displays distinctive textures, structures, and mechanical properties [ 1 , 2 , 3 ]. Since the engineering properties of semi-diagenetic rocks are different from that of loose Quaternary sediments or tough rocks, investigations into and the determination of the physical parameters of semi-diagenesis rocks are lacking [ 1 , 2 , 3 ]. Currently, one of the applicable methods is drilling to collect strata samples, and then, field descriptions, in situ tests, and laboratory experiments would be carried out.…”

Recently, with the development of geophysical exploration technology, geophysical engineering instruments and methods have also improved. The multi-electrode resistivity method is widely used in engineering exploration. In this paper, multi-electrode resistivity tests were carried out in a seasonal frozen soil area in Heilongjiang Province, to provide an optimized multi-electrode resistivity method under the conditions of frozen soil. Combined with shear wave velocity tests and standard penetration tests, multi-electrode resistivity tests were used to comprehensively analyze and evaluate the physical and mechanical properties of Tertiary semi-diagenesis rocks. The results show that the high resistivity due to the frozen surface layer acting as a shield can be eliminated by technical means. It is feasible to test the resistivity through the frozen surface layer. The multi-electrode resistivity method can visually reflect the interface between saturated sand and semi-diagenetic rocks. Dividing the interface between saturated sand and semi-diagenetic rocks is advantageous as the morphology of the resistivity curve has a significant curvature change. There is a strong correlation between the resistance and shear wave velocity of a strata in which the Pearson correlation coefficient is as high as 0.99. The multi-electrode resistivity method test used in combination with the shear wave velocity test and the standard penetration test could give the bearing capacity and frictional resistance of semi-diagenetic rocks, which saves a lot of time and material costs in engineering exploration.
