چکیده

We present a new differential-thickness coating technique to analyze insulating samples with X-ray PhotoElectron Emission spectroMicroscopy (X-PEEM). X-PEEM is non-destructive, analyzes the chemical composition and crystal structure of minerals and can spatially resolve chemical species with a resolution presently reaching 35 nm. We tested the differential coating by analyzing a 4.4 billion-year-old zircon (ZrSiO(4)) containing silicate inclusions. We observed quartz (SiO(2)) inclusions smaller than 1microm in size that can only be analyzed non-destructively with synchrotron spectromicroscopies. With the removal of charging we greatly extend the range of samples that can be analyzed by X-PEEM.

Potentially biogenic carbon preserved in a 4.1 billion-year-old zircon.

Evidence of life on Earth is manifestly preserved in the rock record. However, the microfossil record only extends to ∼ 3.5 billion years (Ga), the chemofossil record arguably to ∼ 3.8 Ga, and the rock record to 4.0 Ga. Detrital zircons from Jack Hills, Western Australia range in age up to nearly 4.4 Ga. From a population of over 10,000 Jack Hills zircons, we identified one >3.8-Ga zircon that ...

Thermometry and determine the characterization of magma of Cretaceous acidic rocks using the zircon mineral morphology and compare it with whole-rock chemistry in SE Saqqez, NW Iran

Zircon is an stable mineral during post crystallization processes and preserves characters of magmatic events. Zircon morphology can give some information about temperature, nature, and source of the magma. Study of the zircon morphology of Cretaceous granitoids and acidic volcanics from the southeast Saqqez area reveals that most of the crystals are P5 and S25 types with high alkalinity (I.A.)...

Oxygen isotope ratios and rare earth elements in 3.3 to 4.4 Ga zircons: Ion microprobe evidence for high O continental crust and oceans in the Early Archean

Ion microprobe analyses of oxygen isotope ratios in Early Archean (Hadean) zircons (4.0to 4.4-Ga) reveal variable magmatic O values, including some that are high relative to the mantle, suggesting interaction between magmas and already-formed continental crust during the first 500 million yr of Earth’s history. The high average O value of these zircons is confirmed by conventional analysis. A m...

Lunar Zircons : What ’ S the Big Picture ?

Introduction: Zircon is a late stage accessory mineral that incorporates radiogenic parents such as uranium and thorium, while preferentially excluding their daughter product lead, allowing for precise U-Pb and Pb-Pb ages to be determined for individual grains [1]. Zircons also incorporate other trace elements such as the rare earth elements (REEs) and titanium, which can reflect the compositio...

Assessing Inheritance of Zircon and Monazite in Granitic Rocks from the Monashee Complex, Canadian Cordillera

Zircon and monazite from granitic sheets and dikes in the Monashee complex, Canadian Cordillera, were investigated to determine whether igneous crystallization occurred at 1.9 Ga or 50 Ma with 1.9 Ga inherited zircon and monazite. Four of the five samples are weakly deformed to undeformed, despite occurring in a gneiss dome at the structurally deepest exposed level of the orogen that elsewhere ...
