Hardly any previous studies have focused on the granitic dykes which intrude into Paleoproterozoic Liaohe Group in Liaodong Peninsula, northeast of North China Craton. In situ zircon U-Pb dating, Lu-Hf isotopic and geochemical analyses three representative monzogranite were taken this study. These relatively high content SiO2 (72.20%–74.78%) K2O (2.83%–6.37%), characteristics high-K calc-alkali...

Igneous intrusions in sedimentary basins can influence basin-scale fluid flow and petroleum systems various ways. They may act as barriers, preferential pathways or even reservoirs for fluids. The fracture networks of usually represent the main control their hydraulic properties. However, our understanding different fracturing mechanisms quantitative effect on network properties remains limited...

Igneous sheet-complexes transport magma through the crust, but most studies have focused on single segments of magma-transport-system or low resolution. In Jameson Land Basin in East Greenland, reflection-seismic data and extensive outcrops give unparalleled constraints mafic intrusions down to 15 km. This dataset shows how sill-complexes develop is transported from mantle sedimentary basins. T...

Fluid-assisted mass transfer and re-equilibration of mineral phases are common consequences metasomatism associated with igneous intrusions. The addition and/or removal chemical components in these environments may result the generation metasomatic aureoles, which can be recognized by their mineralogy geochemistry. Due to an increasing demand for critical raw materials used green energy technol...

Post-mineralization activities may cause difficulties in the process of ore modeling in porphyry deposits. Sungun, NW Iran, is one of the porphyry copper deposits, in which dyke intrusions have made ore modeling more complicated than expected. Among different kinds of dykes, two types were chosen and the consequent geostatistical analyses were applied on. In this study, simple directional vario...

Crustal extension at the East African Rift System (EARS) should, as a tectonic ideal, involve a stress field in which the direction of minimum horizontal stress is perpendicular to the rift. A volcano in such a setting should produce dykes and fissures parallel to the rift. How closely do the volcanoes of the EARS follow this? We answer this question by studying the 21 volcanoes that have erupt...
