The Kızıldağ (Hatay) ophiolite in southern Turkey represents a complete, although fault-dissected, remnant of oceanic lithosphere that formed within the South Tethyan ocean during late Cretaceous. forms part Upper Cretaceous belt which includes Troodos (Cyprus), Baer-Bassit (Syria), Amanos (S Tukey), S Iran and Semail (Oman) ophiolites. Ion-probe (SIMS) dating seven samples crustal rocks (cumul...

Loveringite, a rare member of the crichtonite group with nominal formula (Ca,Ce)(Ti,Fe,Cr,Mg)21O38, was found in Khamal layered mafic intrusion, first known locality for this mineral Arabian Shield. The large post-collisional complex, is lithologically zoned, bottom to top, from olivine gabbro through gabbronorite, hornblende gabbro, anorthosite, and diorite quartz diorite. Loveringite near bas...

Melt inclusions with large, positive Sr anomalies have been described in multiple tectonic settings, and the origins of this unusual geochemical feature are debated. Three proposed, all involving plagioclase as source elevated Sr: (i) direct assimilation plagioclase-rich lithologies, (ii) recycled lower oceanic gabbro mantle source, (iii) shallow-level diffusive interaction between present day ...

Volcán San Pedro in the Andean Southern Volcanic Zone (SVZ) Consequently, the role of young, unradiogenic hydrous gabbro in Chile, comprises Holocene basaltic to dacitic lavas with trace generating dacite and contaminating basalt may be underappreciated element and strontium isotope ratios more variable than those of in the SVZ. most Pleistocene lavas of the underlying Tatara–San Pedro complex....

taposed along the north-trending, high-angle Nahlin fault; all three tectonic elements are intruded by the Late Cretaceous Atlin Mountain pluton (Figure 1-19-2). The oldest rocks in the eastern domain are Mississippian to Triassic oceanic; crustal and sedimentary rocks of the Cache Creek Complex. These include ultramafite, basalt, limestone, chert, argillite and wacke, and probably a mixed ultr...

The Bikilal layered gabbro-complex is composed of zones/layers of olivine/ pyroxene gabbro and hornblende gabbro. Within the hornblende gabbro, repeated lens-like thin and elongated bodies of hornblendite are found intimately associated with massive and disseminated ilmenite-magnetite bodies, in places with apatite. Petrological examination of the hornblende gabbro shows 50-55% hornblende, 40-4...

Methods content petrogenic oxides was determined using silicate analysis; rare elements were determ ined ICP-MS methods by an EIAH 9000 mass spectrometer ICP-AES ICPE-9000 spectrometer.

The present study aimed to evaluate the ability of a mixture gabbro powder and dacite promote plant growth, provide nutrients alter soil chemical characteristics. Two experiments were conducted under different field conditions, in which black oat beans added with increasing doses (0 10 t ha-1) rock blend. grain yield (beans), dry matter production (oats) nutritional status crops evaluated. At e...
