<meta content="The frequency distributions of elements in rocks and ore deposits do not conform to a universal scaling law, but vary in dependence of the mechanism of element enrichment. In the present contribution a dynamic model is proposed that describes element enrichments taking place by metasomatic processes causing the formation of hydrothermal ore deposits. It is shown that metasomatic element enrichment can result in a fractal distribution of element abundance data in the low concentration region
with a smooth truncation at higher concentration values due to the existence of physical upper concentration limits imposed by the mineralogical nature of the ore. The developed model is tested on the basis of base and precious metal concentration data determined on diamond drill core samples collected from the Waterloo massive sulfide deposit, Australia. It is shown that the frequency distributions of Zn, Pb, Cu, and Ag conform relatively well to truncated power–law relationships as predicted by the
model. In contrast, the frequency distribution of the Au data was found to be better described by the log-normal law, presumably due to syn-genetic processes of element redistribution that have not been modeled by the proposed dynamic model." name="eprints.abstract" />

In the present contribution a dynamic model is proposed that describes element enrichments taking place by metasomatic processes causing the formation of hydrothermal ore deposits. It is shown that metasomatic element enrichment can result in a fractal distribution of element abundance data in the low concentration region&#13;
with a smooth truncation at higher concentration values due to the existence of physical upper concentration limits imposed by the mineralogical nature of the ore. The developed model is tested on the basis of base and precious metal concentration data determined on diamond drill core samples collected from the Waterloo massive sulfide deposit, Australia. It is shown that the frequency distributions of Zn, Pb, Cu, and Ag conform relatively well to truncated power–law relationships as predicted by the&#13;
model. In contrast, the frequency distribution of the Au data was found to be better described by the log-normal law, presumably due to syn-genetic processes of element redistribution that have not been modeled by the proposed dynamic model.</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">The definitive version is available at http://www.sciencedirect.com/</td></tr><tr><th valign="top" class="ep_row">Keywords:</th><td valign="top" class="ep_row">truncated fractal frequency distribution; massive sulfide deposits; base and precious metals; metasomatic processes</td></tr><tr><th valign="top" class="ep_row">Subjects:</th><td valign="top" class="ep_row"><a href="http://eprints.utas.edu.au/view/subjects/260100.html">260000 Earth Sciences &gt; 260100 Geology</a></td></tr><tr><th valign="top" class="ep_row">ID Code:</th><td valign="top" class="ep_row">2014</td></tr><tr><th valign="top" class="ep_row">Deposited By:</th><td valign="top" class="ep_row"><span class="ep_name_citation"><span class="person_name">Mrs Katrina Keep</span></span></td></tr><tr><th valign="top" class="ep_row">Deposited On:</th><td valign="top" class="ep_row">04 Oct 2007 14:52</td></tr><tr><th valign="top" class="ep_row">Last Modified:</th><td valign="top" class="ep_row">09 Jan 2008 02:30</td></tr><tr><th valign="top" class="ep_row">ePrint Statistics:</th><td valign="top" class="ep_row"><a target="ePrintStats" href="/es/index.php?action=show_detail_eprint;id=2014;">View statistics for this ePrint</a></td></tr></table><p align="right">Repository Staff Only: <a href="http://eprints.utas.edu.au/cgi/users/home?screen=EPrint::View&amp;eprintid=2014">item control page</a></p>
