Saskatchewan a pionierat tehnica înghețării sărurilor umede (formarea Blairmore) pentru a le manevra prin puțurile miniere. Principala companie minieră este <i>Corporația de Potasă din Saskatchewan</i>. Oceanele reprezintă o altă sursă de potasiu, însă cantitatea prezentă într-un volum dat de apa de mare este relativ scăzut, în comparație cu sodiul.<sup id="cite_ref-USGSCS2008_33-0" class="reference"><a href="#cite_note-USGSCS2008-33"><span class="cite-bracket">[</span>33<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-USGSYB2006_34-0" class="reference"><a href="#cite_note-USGSYB2006-34"><span class="cite-bracket">[</span>34<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Izotopii_potasiului">Izotopii potasiului</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Potasiu&veaction=edit&section=5" title="Modifică secțiunea: Izotopii potasiului" class="mw-editsection-visualeditor"><span>modificare</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Potasiu&action=edit&section=5" title="Edit section's source code: Izotopii potasiului"><span>modificare sursă</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Potasiul are 24 de <a href="/wiki/Izotop" title="Izotop">izotopi</a> cunoscuți, dintre care trei sunt întâlniți în <a href="/wiki/Natur%C4%83" title="Natură">natură</a> în următoarele proporții: <sup>39</sup>K (93,3%)<sup id="cite_ref-autogenerated29_35-0" class="reference"><a href="#cite_note-autogenerated29-35"><span class="cite-bracket">[</span>35<span class="cite-bracket">]</span></a></sup> <sup>40</sup>K (0,0117%)<sup id="cite_ref-autogenerated29_35-1" class="reference"><a href="#cite_note-autogenerated29-35"><span class="cite-bracket">[</span>35<span class="cite-bracket">]</span></a></sup> și <sup>41</sup>K (6,7%).<sup id="cite_ref-autogenerated29_35-2" class="reference"><a href="#cite_note-autogenerated29-35"><span class="cite-bracket">[</span>35<span class="cite-bracket">]</span></a></sup> Izotopul <sup>40</sup>K se <a href="/wiki/Dezintegrare" class="mw-disambig" title="Dezintegrare">dezintegrează</a> în izotopul stabil <a href="/wiki/Argon" title="Argon"><sup>40</sup>Ar</a> (11,2% din dezintegrări) prin captura <a href="/wiki/Electron" title="Electron">electronică</a> sau emisie de <a href="/wiki/Pozitron" title="Pozitron">pozitroni</a>, sau se descompune în <a href="/wiki/Calciu" title="Calciu"><sup>40</sup>Ca</a> (88,8% din dezintegrări) prin <a href="/wiki/Dezintegrare_beta" title="Dezintegrare beta">dezintegrare beta</a>;<sup id="cite_ref-36" class="reference"><a href="#cite_note-36"><span class="cite-bracket">[</span>36<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-autogenerated28_37-0" class="reference"><a href="#cite_note-autogenerated28-37"><span class="cite-bracket">[</span>37<span class="cite-bracket">]</span></a></sup> <sup>40</sup>K are un timp de înjumătățire de 1.250×10<sup>9</sup> ani.<sup id="cite_ref-autogenerated33_38-0" class="reference"><a href="#cite_note-autogenerated33-38"><span class="cite-bracket">[</span>38<span class="cite-bracket">]</span></a></sup> </p><p>Dezintegrarea izotopului <sup>40</sup>K în <sup>40</sup>Ar activează o metodă folosită în datarea rocilor.<sup id="cite_ref-39" class="reference"><a href="#cite_note-39"><span class="cite-bracket">[</span>39<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-40" class="reference"><a href="#cite_note-40"><span class="cite-bracket">[</span>40<span class="cite-bracket">]</span></a></sup> Metoda convențională de datare prin potasiu și argon presupune că rocile nu conțineau argon la momentul formării și că argonul radiogenic a fost reținut cantitativ (de exemplu <sup>40</sup>Ar).<sup id="cite_ref-41" class="reference"><a href="#cite_note-41"><span class="cite-bracket">[</span>41<span class="cite-bracket">]</span></a></sup> <a href="/wiki/Mineral" title="Mineral">Mineralele</a> sunt datate prin măsurarea concentrației de potasiu și de <sup>40</sup>Ar radiogenic acumulat.
