Composite dike systems are a common feature in the basement complex of the Egyptian Eastern Desert and Sinai. These dike systems cut several lithological units, but mostly concentrated in…
Significance of assimilation and fractional crystallization (AFC) process in the generation of basaltic lava flows from Chhotaudepur area, Deccan Large Igneous Province, NW India
- GeologyJournal of Earth System Science
- 2018
Basaltic and basaltic andesitic flows have been identified from the Chhotaudepur area in the Deccan Large Igneous Province. The $$\hbox {SiO}_{2}$$SiO2 content of these flows varies from 46.7 to 53.7…
Geochemical Features and Magma Source Regional Characteristics of the Post-Collisional Plio-Quaternary Gözucu (Taşlıçay-Ağrı) Volcanics, Eastern Anatolia, Turkey
- Geology
- 2020
This study aimed to determine the petrographic and geochemical features of the Plio-Quaternary Gözucu (Taşlıçay-Ağrı) volcanics. These volcanics have subalkaline, calc-alkaline, high-K-series and…
On the occurrence, trace element geochemistry, and crystallization history of zircon from in situ ocean lithosphere
- Geology
- 2009
We characterize the textural and geochemical features of ocean crustal zircon recovered from plagiogranite, evolved gabbro, and metamorphosed ultramafic host-rocks collected along present-day slow…

Dating the Growth of Oceanic Crust at a Slow-Spreading Ridge
- GeologyScience
- 2005
Nineteen uranium-lead zircon ages of lower crustal gabbros from Atlantis Bank, Southwest Indian Ridge, constrain the growth and construction of oceanic crust at this slow-spreading midocean ridge.…
Do the trace element compositions of detrital zircons require Hadean continental crust
- Geology
- 2006
The trace element compositions of Hadean zircons have been used in two ways to argue for the existence of Hadean continental crust. One argument is based on low crystallization temperatures of Hadean…
Trace element chemistry of zircons from oceanic crust: A method for distinguishing detrital zircon provenance
- Geology
- 2007
We present newly acquired trace element compositions for more than 300 zircon grains in 36 gabbros formed at the slow-spreading Mid-Atlantic and Southwest Indian Ridges. Rare earth element patterns…

Contrasting Cooling Rates in the Lower Oceanic Crust at Fast- and Slow-spreading Ridges Revealed by Geospeedometry
- Geology
- 2007
Two approaches to determining the high-temperature (� 10008 Ct o � 6008C) cooling rate of the lower oceanic crust and upper mantle are presented and critically evaluated.The first is based on the…
Ti-in-zircon thermometry: applications and limitations
- Geology
- 2008
The titanium concentrations of 484 zircons with U-Pb ages of ∼1 Ma to 4.4 Ga were measured by ion microprobe. Samples come from 45 different igneous rocks (365 zircons), as well as zircon megacrysts…
Corrugated slip surfaces formed at ridge–transform intersections on the Mid-Atlantic Ridge
- GeologyNature
- 1997
The strips of ocean crust formed at the inside corners of both transform and non-transform offsets on the Mid-Atlantic Ridge are punctuated by topographic highs—the 'inside-corner highs'1–3—where…
New thermodynamic models and revised calibrations for the Ti-in-zircon and Zr-in-rutile thermometers
- Geology
- 2007
The models recognize that ZrSiO4, ZrTiO4, and TiSiO4, but not ZrO2 or TiO2, are independently variable phase components in zircon. Accordingly, the equilibrium controlling the Zr content of rutile…
