BADDELEYITE-APATITE-SPINEL-PHLOGOPITE (BASP) ROCK IN ACHANKOVIL SHEAR ZONE, SOUTH INDIA, AS A PROBABLE CUMULATE FROM MELTS OF CARBONATITE AFFINITY

Rajesh V.J.; Arai S. (2006)

We report here the petrography, mineralogy and in-situ trace-element mineral geochemistry of a rare and hitherto unidentified baddeleyite-apatite-spinel-phlogopite (BASP) rock in Late Neoproterozoic Achankovil Shear Zone ...
CRYSTAL ORIENTATION EFFECTS DURING ION MICROPROBE U-PB ANALYSIS OF BADDELEYITE

Wingate M.T.D.; Compston W. (2000)

We show that 206Pb/238U ratios measured in baddeleyite by ion microprobe vary significantly (up to +/-10% or more) and systematically with the relative orientation of the baddeleyite crystal structure and the primary ion ...
DETERMINATIONS OF ZR ISOTOPIC COMPOSITION AND U-PB AGES FOR TERRESTRIAL AND EXTRATERRESTRIAL ZR-BEARING MINERALS USING LASER ABLATION-INDUCTIVELY COUPLED PLASMA MASS SPECTROMETRY: IMPLICATIONS FOR NB-ZR ISOTOPIC SYSTEMATICS

Hirata T. (2001)

Isotopic composition of zirconium from eight zircon and two baddeleyite samples including meteoritic zircon have been measured using a laser ablation-multiple collector-inductively coupled plasma mass spectrometer ...
