Hemimorphite

<h2 id="occurrence">Occurrence</h2>

<p>Hemimorphite most frequently occurs as the product of the <a href="/facts/Oxidation/Pyd5RVcj">oxidation</a> of the upper parts of <a href="/facts/Sphalerite/5NumvnzR">sphalerite</a> bearing ore bodies, accompanied by other secondary minerals which form the so-called <i>iron cap</i> or <i><a href="/facts/Gossan/hAmPJD6D">gossan</a></i>. Hemimorphite is an important <a href="/facts/Ore/kgc9DssX">ore</a> of zinc and contains up to 54.2% of the metal, together with silicon, oxygen and hydrogen. The crystals are blunt at one end and sharp at the other.

<p>The regions on the <a href="/facts/Belgium/YKuMXP5j">Belgian</a>-<a href="/facts/Germany/paluuWBX">German</a> border are well known for their deposits of hemimorphite of metasomatic origin, especially <a href="/facts/Vieille_Montagne/WkUfHRYH">Vieille Montagne</a> in Belgium and <a href="/facts/Aachen/dD9LBC5g">Aachen</a> in Germany. Other deposits are in <a href="/facts/Tarnowskie_G%C3%B3ry/nC9JcL1t">Tarnowskie Góry</a> area in <a href="/facts/Upper_Silesia/NHm8MPN6">Upper Silesia</a>, <a href="/facts/Poland/eXJ7fd0D">Poland</a>; near <a href="/facts/Phoenixville,_Pennsylvania/uMMQmHtm">Phoenixville</a>, <a href="/facts/Pennsylvania/HGqC5bBm">Pennsylvania</a>; the <a href="/facts/Missouri/wQ3VAb99">Missouri</a> lead-zinc district; <a href="/facts/Elkhorn,_Montana/QLgh5BBX">Elkhorn</a>, <a href="/facts/Montana/jPFKMuK5">Montana</a>; <a href="/facts/Leadville/1vERhzXB">Leadville</a>, <a href="/facts/Colorado/IgIHrJI5">Colorado</a>; and <a href="/facts/Organ_Mountains/W1jgNuo3">Organ Mountains</a>, <a href="/facts/New_Mexico/wosJCGaW">New Mexico</a> in the United States; and in several localities in <a href="/facts/North_Africa/ItxQAfs7">North Africa</a>. Further hemimorphite occurrences are the Padaeng deposit near Mae Sod in western <a href="/facts/Thailand/GCUnN4JK">Thailand</a>; <a href="/facts/Sardinia/7GGJNHCx">Sardinia</a>; <a href="/facts/Nerchinsk/m1YmIrtf">Nerchinsk</a>, <a href="/facts/Siberia/oaCoPEjF">Siberia</a>; <a href="/facts/Cave_del_Predil/dCYcSSXW">Cave del Predil</a>, <a href="/facts/Italy/tUf0PDYF">Italy</a>; <a href="/facts/Bleiberg/dwGkmnmR">Bleiberg</a>, <a href="/facts/Carinthia_(state)/KYdoqzvx">Carinthia</a>, <a href="/facts/Austria/4qWIMIyc">Austria</a>; <a href="/facts/Matlock,_England/QeCPCX6m">Matlock</a>, <a href="/facts/Derbyshire/cWS0T6gV">Derbyshire</a>, England.
