Erratum to: An experimental study of Ti and Zr partitioning among zircon, rutile, and granitic melt

Amy E. Hofmann; M. B. Baker; John M. Eiler

A number of other small errors were introduced during typesetting that, nevertheless, may lead to some confusion on the part of the reader. Corrections are listed below. On page 246, in the right-hand column below Eq. 2, a superscript was omitted. The correct expression is: (aZrO2) rt ≈ X ZrO2. Similarly, the following non-superscripted instances of XZrO2 in the right-hand column on page 246 should be X ZrO2. On page 247, in the left-hand column, XZrO2(XZrO2 − 2)W should be: X ZrO2(X rt ZrO2 − 2)W and (XZrO2) in the first line of the caption to Fig. 7 should be (X ZrO2). On page 248 in the sentence immediately following Eq. (4), a comma was introduced into the value of coefficient b. The correct value is b = 0.00421. In the left-hand column on page 250, parentheses are missing; the corrected text should read: ...between zircon and melt (D Ti ) to be calculated... Finally, on that same page (right-hand column), the Greek letter alpha appears to have been substituted for a proportionality symbol. The corrected text should be:
