Abstract Magma emplacement in the top unconsolidated sediments of rift basins is poorly understood. We compare two shallow sills from Guaymas Basin (Gulf California) using core data and analyses IODP Expedition 385, high‐resolution 2D seismic data. show that magma stalling uncemented sediment layer controlled by transition siliceous claystone to silica‐rich sediment, favoring flat sill formation. Space created through a combination viscous indentation, magma‐sediment mingling fluidization...
Abstract This paper discusses the development, testing and optimization of a rotary steerable system (RSS) developed specifically to address challenges around drilling wells in unconventional reservoirs North America. As with offshore areas, technology has rapidly gained acceptance for onshore use because its clear advantages directional control, wellbore placement lateral reach, while matching or exceeding performance conventional systems. The further growth RSS into been limited by...
Magma emplacement in the top unconsolidated sediments of rift basins is poorly constrained terms mechanics and associated hydrothermal activity. Our study compares two shallow sills from Guaymas Basin (Gulf California) using core data analyses IODP Expedition 385, high-resolution 2D seismic data. We show that magma stalling uncemented sediment layer controlled by transition siliceous claystone to silica-rich sediment, promoting flat sill formation. Space created through a combination viscous...
Permanent carbonate mineralisation in basalt is a promising solution for Carbon Capture and Storage of anthropogenic greenhouse gases without the risk leakage. While this process known to occur at relatively low temperatures below 100°C, new research on Large Igneous Provinces (LIPs) young rift basins suggests that much thermogenic mobilised during contact metamorphism can remain trapped mineralised sills them. This discovery result two distinct drilling investigations land (KARIN)...

&lt;p&gt;Magma-sediment mingling occurring in shallow porous sediments is mainly investigated through field observations of old exhumed rift basins. During the IODP Expedition 385 we have drilled sills emplaced active Guaymas Basin, Gulf California. The results this expedition enable a pioneer study impact recent magma-sediment processes leading to peperite formation. Furthermore, it provides present-day geological context investigate and quantify process on element cycles subsurface...
&lt;p&gt;Magma emplacement and the mingling of sediment with magma (forming peperite facies) in unconsolidated, near-surface basin sediments have been described fossil systems but not reported active settings. The IODP Expedition 385 drilled through soft (first 500 m) Guaymas Basin, a young marginal rift Gulf California. This is characterized by an unusually high spatial density sill intrusions emplaced off-axis. One sills, inferring within 200 m depth below seafloor (Site U1547),...
