Please accept my sincerest apologies for not responding to you sooner. I was away on holiday. Unfortunately, the SEG does not permit reprinting of full articles in any electronic format. The only thing we could allow would be the abstract of this article. The cost would be $10.00 a page. Please let me know if you are still interested and I will be happy to prepare the Reprint Permission Request and the Invoice. If you have any questions, or if I may be of further assistance, please do not hesitate to contact me.

We report new Pb isotope data for the Nifty deposit and the Rainbow and Grevillea prospects. These data are combined with published and unpublished data to characterize the Pb isotope signatures of the deposits and prospects in the Throssell Group. In addition these data are integrated into a model for the sources of Pb in the mineralizing systems. Lead isotope data from mineralized occurrences in the Throssell Group plot as a linear trend in 207Pb/204Pb- 206Pb/204Pb space. Deposits and prospects are arranged, from least to most radiogenic, as Rainbow, Warrabarty, Nifty, Goosewacker, and Maroochydore, along the trend. Secondary isochron or mixing isochron models were previously proposed to interpret the Pb isotope trend for mineral deposits and prospects in the Throssell Group. Our investigation shows that the linear trend does not represent an isochron due to the syngenetic (pre- D4) timing for mineralization at Warrabarty and Rainbow compared to an epigenetic (syn-D4) timing for Maroochydore, Nifty, and Goosewacker. We propose a source-mixing model, with no time dependency, to explain the deposit Pb isotope linear trend where Pb from a primitive, mantle source (Pilbara Craton, μ = 9.88) is mixed with crustal Pb (Throssell Group sedimentary rock derived from the Rudall Complex, μ = 10.55). The position of deposits and prospects along the trend suggests that the Warrabarty and Rainbow prospects have more primitive Pb and that the Maroochydore deposit contains Pb from primarily a crustal source. The Nifty deposit, and the Goosewacker and Grevillea prospects, contain a mixture of both primitive and crustal Pb." name="eprints.abstract" /> <meta content="2002-07" name="eprints.date" /> <meta content="published" name="eprints.date_type" /> <meta content="Economic Geology" name="eprints.publication" /> <meta content="97" name="eprints.volume" /> <meta content="4" name="eprints.number" /> <meta content="897-911" name="eprints.pagerange" /> <meta content="10.2113/97.4.897" name="eprints.id_number" /> <meta content="TRUE" name="eprints.refereed" /> <meta content="0361-0128" name="eprints.issn" /> <meta content="http://dx.doi.org/10.2113/97.4.897" name="eprints.official_url" /> <meta content="Anderson, B.R., 1999, Structure, alteration and mineralization of the Nifty copper deposit, Western Australia: Implications for ore genesis: Unpublished Ph.D. thesis, Hobart, Australia, University of Tasmania, 225 p.

We report new Pb isotope data for the Nifty deposit and the Rainbow and Grevillea prospects. These data are combined with published and unpublished data to characterize the Pb isotope signatures of the deposits and prospects in the Throssell Group. In addition these data are integrated into a model for the sources of Pb in the mineralizing systems. Lead isotope data from mineralized occurrences in the Throssell Group plot as a linear trend in 207Pb/204Pb- 206Pb/204Pb space. Deposits and prospects are arranged, from least to most radiogenic, as Rainbow, Warrabarty, Nifty, Goosewacker, and Maroochydore, along the trend. Secondary isochron or mixing isochron models were previously proposed to interpret the Pb isotope trend for mineral deposits and prospects in the Throssell Group. Our investigation shows that the linear trend does not represent an isochron due to the syngenetic (pre- D4) timing for mineralization at Warrabarty and Rainbow compared to an epigenetic (syn-D4) timing for Maroochydore, Nifty, and Goosewacker. We propose a source-mixing model, with no time dependency, to explain the deposit Pb isotope linear trend where Pb from a primitive, mantle source (Pilbara Craton, μ = 9.88) is mixed with crustal Pb (Throssell Group sedimentary rock derived from the Rudall Complex, μ = 10.55). The position of deposits and prospects along the trend suggests that the Warrabarty and Rainbow prospects have more primitive Pb and that the Maroochydore deposit contains Pb from primarily a crustal source. The Nifty deposit, and the Goosewacker and Grevillea prospects, contain a mixture of both primitive and crustal Pb.</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Additional Information:</th><td valign="top" class="ep_row">Copyright 2002, Society of Economic Geologists. email reply (27/11)mmc Dear Ms. McCoy, Thank you for your e-mail.
