Although the number of incarcerated females is rapidly increasing, few of us will have actual contact with women in a correctional setting. For the most part, our ideas about female inmates and the prisons they are housed in come from filmic images – images that, though highly accessible to the public, depict inaccurate accounts of prison life. From the use of unlikely characters and their corr...

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...
