Garnets radiogenic isotopes

Zhuravlev A. Z., Laz ko Y. Y., and Ponomarenko A. I. (1991) Radiogenic isotopes and REE in garnet peridotite xenoliths from the Mir kimberlite pipe, Yakutia. Geokhimiya 7, 982-994. [Pg.977]

When ultramafic rocks were initially analyzed for strontium isotopes (Hurley et al, 1964 Roe, 1964 Stueber and Murthy, 1966 Lanphere, 1968) only whole rocks were analyzed. Such data led to numerous erroneous conclusions about the relationship between mantle samples and basalts due to the pervasive alteration suffered by many ultramafic rocks, enhancing the amount of radiogenic strontium present. Subsequent studies have shown that acid-washed mineral separates, particularly diopside and garnet, are the most reliable means of obtaining the primary, unaltered... [Pg.923]
