“…The Neoseongsan block located at the western part of the basin was considered a particularly promising CO 2 reservoir because it mainly consists of rudaceous sandstone lithofacies and conglomerate layers, and the dacitic tuff (i.e., low-permeability layer) acted as a cap rock [18,35]. Because of the Miocene basaltic volcanism, considerable intrabasinal faults were not found; however, the basin is characterized by a disturbed geometry near the surface [36].…”

The geological sequestration of carbon dioxide (CO2) is an alternative strategy for mitigating global warming. The CO2 storage capacity is often characterized by the capillary pressure curve, which in turn depends on the pressure and temperature of the injected CO2 and the internal structure of the reservoir rocks. The key structural feature that influences the storage capacity in porous rocks is their inherent anisotropy. An experimental study was performed to investigate the optimal conditions for CO2 injection into an anisotropic sandstone. The capillary pressure curve and the residual CO2 saturation were determined by injecting three CO2 phases into the directionally cored sandstone specimens with different flow rates. The CO2 saturation in sandstone increased with increasing flow rate, resulting in asymptotic values. The storage capacity of CO2 was the highest in the order of liquid CO2 (LCO2), supercritical CO2 (scCO2), and gaseous CO2 (gCO2). It was also the highest when the direction of CO2 injection was normal in relation to the embedded sandstone layers. The in situ cored sandstone from the Janggi Basin in Korea was further tested to examine the effect of its pore size on the capillary pressure of CO2.

“…The basin is bounded by the Ocheon Fault System on the north‐west, whereas it is bounded to the south and west by normal faults and dextral strike‐slip faults, respectively (Fig. 2) (Kim et al ., 2020). The eastern margin of the basin is submerged below sea level.…”

“…Recent results of field mapping suggest that the Janggi Basin can be divided into five subbasins, named as Guryongpo, Ocheon, Noeseongsan, Yeongamri and Yangpo subbasins, on the basis of the relative chronology of basin fill, lithological character, attitude of strata and the presence of bounding faults (Fig. 2; Kim et al ., 2020). Most of the subbasins were filled with alternating beds of dacitic tuff and terrestrial sediment (upper part of Beomgokri Group), and are conformably overlain or intruded by basaltic volcaniclastic and volcanic rocks (Janggi Group), except for the Guryongpo Subbasin in which dacitic volcanic rocks are the dominant lithofacies (lower part of Beomgokri Group) (Fig.…”

Strata of the Beomgokri Group are generally inclined to the north‐western marginal fault except for areas where the Janggi Group overlies the Beomgokri Group because of basaltic hydrovolcanic eruptions and resultant local subsidence during deposition of the Janggi Group (Fig.…”

“…In this study, the Miocene Janggi Basin was investigated to understand how tectonic activity influences the formation of volcano‐sedimentary successions. This basin is a terrestrial pull‐apart basin (Son et al ., 2015; Kim et al ., 2020), filled with fluvio‐lacustrine sediments showing a half‐graben geometry as a result of syndepositional tectonic subsidence along basin‐bounding faults. During sedimentation, explosive dacitic volcanism caused episodic but basinwide deposition of tens of metres thick, pyroclastic sediments via pyroclastic density currents (PDCs).…”

In extensional and transtensional basins, the dual action of basin-forming tectonism and explosive volcanic activity results in deposition of complex volcano-sedimentary successions. Since both aspects contemporaneously affect sediment-dispersal systems, it is difficult to distinguish one from the other by analyzing volcano-sedimentary successions. To discriminate tectonic influence, basin fills of the Miocene, pull-apart Janggi Basin were investigated. Here, the contemporaneous influence of tectonic subsidence and explosive volcanism formed <966 m thick, conformable volcanosedimentary successions composed of laterally extensive, pumice-bearing, unwelded pyroclastic deposits and nonmarine sedimentary rocks formed under humid climatic conditions. Based on Laser Ablation -Multiple Collector -Inductively Coupled Plasma Mass Spectrometry zircon U-Pb age data, these successions were deposited from 21.1 AE 0.2 to 20.1 AE 0.1 Ma. After deposition of basinwide, tens of metres thick, and unwelded pyroclastic deposits, the directly overlying facies successions (FS-1 and FS-2) show contrasting depositional features to the classical model of volcaniclastic sedimentation. Facies succession-1 is represented by fluvial conglomerates composed mostly of (sub)rounded pebble and cobble sourced from basement. The supply of basement-derived clasts through fluvial systems resulted from development of physiographic relief during or soon after the eruption by syndepositional tectonic subsidence. Facies succession-2 occurs directly on pyroclastic deposits that cover FS-1 and show coarsening-upward trends, and is composed of basal lacustrine mudstones and overlying resedimented volcaniclastic sandstones showing a progradational geometry, interpreted as a result of progressive filling of the lake by remobilized volcaniclastic sediments. Occurrence of basal lacustrine laminated mudstones indicates that syndepositional creation of the accommodation by tectonic subsidence exceeded forceful input of pyroclastic and remobilized volcaniclastic sediments, resulting in a delayed sedimentary response to explosive volcanic eruptions. This study shows that, despite voluminous production of volcaniclastic sediments, tectonic activity controlled sediment type and stacking patterns. Therefore, these depositional features allow to discriminate tectonic effects from complex volcano-sedimentary successions, enabling to reconstruct basin evolution.
