متن کاملProterozoic crustal evolution in the NW Himalaya (India) as recorded by circa 1.80 Ga mafic and 1.84 Ga granitic magmatism
Single zircon dating of the Rampur metabasalts of the Larji–Kullu–Rampur window in the Lesser Himalayas yielded an evaporation age of 1800913 Ma. The zircon age is considerably younger than the previously published whole rock Sm–Nd age of 2510990 Ma, suggesting that the Sm–Nd age may be geologically meaningless and that the Sm–Nd whole rock array may have resulted from mixing. In the NW Himalay...
متن کاملPetrology, geochemistry, and petrogenesis of mafic dykes from the Kermanshah Ophiolite in Sahneh-Harsin area of Western Iran
The Kermanshah ophiolite complex is a part of the Mediterranean–Zagros–Oman Tethyan ophiolites, located in the structural–tectonic zone of western Iran in the northern part of the Zagros main thrust. Doleritic sheeted dykes are well exposed within the ophiolite in the south of Sahneh. These dykes contain high MgO, Na2O, low TiO2 (2O5, and K2O contents, and high FeOt/MgO and LILE/HFSE ratios. Th...

Crustal geophysics and seismicity in southern California
S U M M A R Y The geographical distribution of the (1981–2005) seismicity in southern California forms a ±150 km broad zone adjacent to the Pacific–North America plate boundary, ranging from depths of ∼1–∼30 km, with the bulk of the focal depths in the range of 2–12 km. The distribution of the seismicity that includes both mainshock–aftershock sequences and background events is affected by both...
