Pb—Pb zircon evaporation date for the Charleston Granite, South Australia: Comparisons with other zircon geochronology techniques

In order to draw attention to the effectiveness of the single‐grain evaporation technique of Pb‐Pb zircon dating, this method has been applied to the Charleston Granite, a Mesoproterozoic granitoid from the South Australian Gawler Craton. The granite has previously been dated by both conventional and SHRIMP U‐Pb techniques permitting comparison of the relative advantages of all three techniques. The date obtained by the evaporation technique for the crystallisation of the main magmatic phase of zircon was 1581 ± 4 Ma (2σ) which is the same within error as the SHRIMP result of 1585 ± 5 Ma (2σ).
