“…The lag duration will depend on, among other things, source rock quality (mainly HI) and the burial and thermal histories, but can be 40 Myr or more (Pepper, 1991;Pepper and Corvi, 1995b;Zhao and Cheng, 1998;Wilkins and George, 2002;Sykes et al, 2014). This is consistent with generation and expulsion histories extracted from the model of Kroeger et al (2022) for the Maui sub-basin and the Kahurangi trough (Fig. 9).…”

“…In the northern part of Taranaki Basin, sub-commercial oil accumulations were discovered in the Kora-1 well that was drilled to target a Miocene-aged submarine volcano (King and Thrasher, 1996;Brett, 2005;Bischoff et al 2021, Kroeger et al, 2022. These oils are assigned to Family 41 and are geochemically correlated with the late Paleocene Waipawa Formation whose organic matter is derived from both terrestrial higher plants and marine algae (Reed, 1992;Killops et al, 1994;Murray et al, 1994;Killops, 1996;Clayton, 2011;Sykes et al, 2012;Naeher et al, 2019).…”

“…It is widely known that magmatic activity plays a key role at continental rift-margins (Wright et al, 2012) and hydrocarbon exploration (Jackson et al, 2017;Xian et al, 2018;Kroeger et al, 2022), magmatic intrusion contributing significantly to the upper crust magma transport network. In recent years, the understanding of the magmatic plumbing system within sedimentary basins has been revolutionised by the study of seismic reflection data sets.…”

The transportation of magma in sedimentary basins often occurs through extensive dyke-sill networks. The role of sills on the plumbing system in rifted margins and the impact of sills on hydrocarbon reservoirs of prospective sedimentary basins has long been an area of great industrial interest and scientific debate. Based on 2D seismic reflection, we present data on how the sills emplaced to form a magmatic plumbing system of the volcanic system for the Zhongjiannan Basin (ZJNB). The results show that sixty-nine sills and fourteen forced folds have been identified. The distribution and geometry of the sills suggest that magma flowed from west to east and then ascended to near the surface. The onlap relationship of the forced folds indicates that the timing of magmatic activities can be constrained at ca. 0.2 Ma. The spatial and temporal occurrences of intrusions imply that the strong post-rift magmatism in ZJNB was associated with the Hainan mantle plume arising from the core-mantle boundary. Furthermore, these forced folds could produce several types of hydrocarbon traps, due to accommodation through bending and uplift of the overlying rock and free surface, but it is critical to evaluate the effect of such emplacement when setting exploration targets.

“…The cooling of subvolcanic intrusions, during and after emplacement, can liberate mineralized fluids that migrate and form ore deposits (Hedenquist & Lowenstern, 1994), and the heat brought by subsurface magma mobilizes groundwater to activate hydrothermal systems (Einsele et al, 1980; Galerne & Hasenclever, 2019; Ingebritsen et al, 2010; Iyer et al, 2017), potentially leading to phreatic volcanic explosions (Gaete et al, 2020; White & Ross, 2011). Large sub‐horizontal sill intrusions emplaced in sedimentary basins can also trigger fast maturation of organic‐rich formations (Iyer et al, 2017; Kroeger et al, 2022; Spacapan et al, 2018) and the generation of large volumes of methane and CO 2 (Aarnes et al, 2011; Svensen et al, 2004). The catastrophic release of these fluids into the atmosphere triggered extreme climate change and mass extinctions during Earth's history (Aarnes et al, 2010; Courtillot & Renne, 2003; Svensen et al, 2009).…”

Cooling subvolcanic igneous intrusions are known to have a substantial impact on fluid flow in the shallow Earth's crust, for example activation of geothermal systems, circulation of mineralized fluids in ore deposits, fast maturation of organic matter in sedimentary rocks and the potential release of large volumes of greenhouse gases, which have triggered mass extinctions during the Earth's history. However, the long‐term post‐cooling legacy of subvolcanic intrusions on fluid flow received much less attention. Here we describe a demonstrative geological example in the Andean foothills, Argentina, showing that igneous intrusions have long‐term effects on fluid flow after their emplacement and cooling. The case study is a ca. 11‐million‐year‐old, eroded subvolcanic conduit, at the rims of which large volumes of bitumen are naturally seeping out on the Earth's surface. This contribution highlights that intense syn‐emplacement fracturing of the magma has created high‐permeability pathways that affect the regional fluid circulations, even millions of years after cooling. Our observations reveal how extinct subvolcanic intrusions have long‐term consequences on subsurface fluid circulations, which need to be accounted for in the exploration of geothermal energy, drinkable groundwater, hydrocarbons and CO2 sequestration in volcanic basins and regions hosting ancient shallow magma intrusions.
