pillow basalts, belonging to late cretaceous yüksekova complex are extensivelly exposed around elazıg in eastern turkey. this unit is a part of southeastern anatolian ophiolite belt and the southern branch of the neotethys. it represents the products of intra- oceanic subduction volcanism and mainly comprises pillow lavas, dykes and associated with sedimentary rocks. pillow lavas and feeder dyk...

marine sequences within several orogenic belts in YunWe report petrological and geochemical data on ultramafic pillow nan, SW China (Figs 1 and 2; Fang et al., 1996). These lavas from Late Palaeozoic marine sequences in Yunnan, SW lavas have been interpreted to be oceanic plateaux or China. These lavas have >26 wt % MgO, euhedral to subhedral seamount eruptive rocks associated with mantle plume...

The Achemmach region is located 40 km to the SW from Meknes city and 6 NE frm Hammam mine. It part of Paleozoic massif Central Morocco. studied area formed by two rock-types: (i) a meta-sedimentary sequence composed Middle Visean limestone shale-sandstone withflyschoid Upper Visean-Namurian age, (ii) magmatic rock series represented volcanic rocks (pillow-lavas), hypovolcanic (dolerites) olivin...

Diabases, pillow lavas and basaltic flows in the Nain-Dehshir ophiolites are marked with flat to slightly depleted pattern in REE chondrite-normalized diagram and are characterized by depletion in HFSE and enrichment in LILE. This geochemical behavior can be considered for lavas erupted in arc-related environments. Clinopyroxene in these rocks shows low content of TiO2 and resemble those found ...

38 Sequences of basaltic pillow lavas that transition upwards with systematic gradation from pillow 39 fragment breccias to fluidal bomb-bearing breccia to bomb-bearing lapilli tuffs are common at 40 Askja volcano, Iceland. Based on the detailed textural investigation of three of these sequences, 41 we argue that they record temporally continuous transition from effusive to explosive products 4...

The Upper Cretaceous Ganj complex, a part of the Jazmurian ophiolitic belt, is located on the western boundary of Jazmurian depression and separated from Kahnuj ophiolitic complex by north-south trending Jiroft fault. The complex consists of lava flows, pillow lavas, acidic plutonic and sedimentary rocks which are intruded by northwest-southeast trending dykes. It does not resemble a classical ...

[1] In Deep Sea Drilling Program (DSDP) Hole 417D in the western central North Atlantic, dips of pillow margins measured in the upper and lower part of basement correlate with tilts predicted from paleomagnetic inclinations in the corresponding parts of the hole. A 40 westward dip of the seafloor around 417Dmatches the tilt predicted from inclinations and pillow margin dips in the uppermost lav...

Pahoehoe lava flows are common in every basaltic province, and their submarine variants, pillow lavas and sheet flows, cover the bulk of the Earth. Pahoehoe flows are emplaced by inflation—the injection of molten lava underneath a solidified crust. Only in the past few years has an understanding of the inflation process and the ability to recognize ancient inflated lava flows been achieved. All...
