Syn-Emplacement Fracturing in the Sandfell Laccolith, Eastern Iceland—Implications for Rhyolite Intrusion Growth and Volcanic Hazards
Felsic magma commonly pools within shallow mushroom-shaped magmatic intrusions, so-called laccoliths or cryptodomes, which can cause both explosive eruptions and collapse of the volcanic edifice. Deformation during laccolith emplacement is primarily considered to occur in the host rock. However, shallowly emplaced laccoliths (cryptodomes) show extensive internal deformation. While deformation o...
متن کاملTwo phases of Mesozoic north-south extension in the eastern Altyn Tagh range, northern Tibetan Plateau
[1] The >300-km long, east striking Lapeiquan fault lies in the eastern Altyn Tagh range along the northern margin of the Tibetan Plateau and was interpreted as a north dipping thrust in early studies. However, our mapping shows that the fault is a south dipping normal fault juxtaposing Archean-Proterozoic gneisses beneath an early Paleozoic volcanic and sedimentary sequence. Its dip angle vari...
متن کاملPlant Communities in Eastern Mongolia
In this contribution is presented a phytosociological description of plant communities, recorded in the phytogeographical district of Eastern Mongolia, including parts of the Dornod (Eastern) and the Choybalsan aymags. The whole district is characterized by steppe vegetation. Other vegetation types, like elm (Ulmus pumila) bush vegetation, shrubbery on sandy and rocky sites, Salix miyabeana bus...
متن کاملChronology of pluton emplacement and regional deformation in the southern Sierra Nevada batholith, California
Cretaceous plutonic rocks of the southern Sierra Nevada batholith between latitudes 35.5°N and 36°N lie in a strategic position that physically links shallow, subvolcanic levels of the batholith to lower-crustal (~35 km deep) batholithic rocks. This region preserves an oblique crustal section through the southern Sierra Nevada batholith. Prior studies have produced large U/Pb zircon data sets f...
متن کاملThree-dimensional shape and emplacement of the Cardenchosa deformed pluton (Variscan Orogen, southwestern Iberian Massif)
The Cardenchosa pluton is a Lower Carboniferous Variscan granite located in the southwestern Iberian Massif. It intruded along the contact between the Sierra Albarrana and Azuaga tectonic units. To the northwest the pluton connects with the leftlateral Azuaga fault. The pluton appears in the footwall of the low-angle normal Casa del Cafe fault, which crops out to the west of the granite. Gravi...
