22 · The zircon hafnium (ε Hf [t] > +12 to +20) and oxygen (δ 18 O = 4.6‰−6.0‰) isotope compositions strongly suggest that these plutons were derived from a typical depleted mantle source. These Hf-O isotope compositions coupled with the absence of zircon inheritance indicate a minimal contribution from partial melting of either subducting ...

Californium - Wikipedia


Californium is a radioactive chemical element with symbol Cf and atomic number 98. The element was first synthesized in 1950 at the Lawrence Berkeley National Laboratory (then the University of California Radiation Laboratory), by bombarding curium with alpha particles (helium-4 ions).It is an actinide element, the sixth transuranium element to be synthesized, and has the second-highest …

U-Pb Heterogeneity in Penglai Zircon Megacrysts | Research ...


Four years ago, the Penglai zircon megacryst was evaluated as a potential reference material. Combined SIMS (1280), laser ICPMS, and ID-TIMS data showed that these large Pliocene zircons were homogenous in oxygen and hafnium isotopes, but the analytical techniques applied were unable to usefully constrain the U-Th-Pb age due to low radiogenic 206Pb (generally 10-20 ppb).
