besteht aus einem einzelnen <strong>chemischen Elemen</strong>t oder aus einer chemischen <strong>Verbindung von mehreren Elementen</strong>. Im Gegensatz zu einem Gestein ist es keine Mischung, sondern man spricht von chemischer Reinheit. Ein Mineral <strong>kommt in der Natur vor</strong> und wird nicht vom Menschen hergestellt.</p> <p>Heute sind mehr als 5.500 verschiedene Mineralien bekannt, und jedes Jahr werden ein paar weitere entdeckt. Allerdings sind die meisten extrem klein und sehr selten, sodass der normale Sammler nur etwa 200 bis 300 verschiedene finden und unterscheiden kann.</p> <p>Es gibt mehrere Möglichkeiten, <strong>wie sich Mineralien bilden</strong> können:<img decoding="async" class="alignright wp-image-1098 size-full" src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" data-src="https://vfmg.de/wp-content/uploads/2020/03/A20140413_151555_R8_S4.jpg" alt="" width="250" height="168" /></p> <ul> <li>Wenn sich Magma abkühlt und erhärtet, können in einem magmatischen Gestein Mineralien (wie z.B. der Olivin) auskristallisieren.</li> <li>Oft fließen wässrige Lösungen in Spalten durch die Gesteine; wenn diese Lösung langsam kälter wird, dann können sich Mineralien bilden (so was ähnliches passiert auch mit den Gasen an einem Vulkan).</li> <li>Wenn ein Gestein durch Temperatur und Druck sich verändert (in ein metamorphes Gestein), dann kann es passieren, dass sich hierdurch neue Mineralien bilden.</li> </ul> <p><img loading="lazy" decoding="async" class="alignleft wp-image-1097 size-full" src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" data-src="https://vfmg.de/wp-content/uploads/2020/03/AWDSC_0007.jpg" alt="" width="250" height="167" />Ein Mineral hat viele <strong>unterschiedliche Eigenschafte</strong>n, die man berücksichtigen muss, um sie zu unterscheiden. Dazu zählen Farbe, Strichfarbe, Glanz, Härte, Dichte (=spezifisches Gewicht), Kristallklasse, Bruch, Spaltbarkeit und noch viele andere. Ganz wichtig ist die Formel, denn sie sagt Dir, aus welchen Elementen das Mineral besteht.<br /> Einige dieser Eigenschaften wollen wir Dir auf der nächsten Seite erklären.</p> <nav class="pagination group"> </nav> <div class="clear"></div> </div> </article> </div> </main> <div class="sidebar s1 collapsed" data-position="left" data-layout="col-3cm" data-sb-id="s1"> <button class="sidebar-toggle" title="Seitenleiste erweitern"><i class="fas sidebar-toggle-arrows"></i></button> <div class="sidebar-content"> <div id="media_image-15" class="widget widget_media_image"><a href="https://steinkern.de"><img width="400" height="117" src="https://vfmg.de/wp-content/uploads/2022/04/Steinkern-Button-3.jpg" class="image wp-image-2723 attachment-full size-full" alt="" style="max-width: 100%; height: auto;" decoding="async" loading="lazy" srcset="https://vfmg.de/wp-content/uploads/2022/04/Steinkern-Button-3.jpg 400w, https://vfmg.de/wp-content/uploads/2022/04/Steinkern-Button-3-300x88.jpg 300w" sizes="auto, (max-width: 400px) 100vw, 400px" /></a></div><div id="media_image-19" class="widget widget_media_image"><a href="https://terra-mineralia.de"><img width="479" height="125" src="https://vfmg.de/wp-content/uploads/2022/04/tm_Webbanner_Image_Kombi_KHtm_230x60px_Aufschluss_220426.jpg" class="image wp-image-2711 attachment-full size-full" alt="" style="max-width: 100%; height: auto;" decoding="async" loading="lazy" srcset="https://vfmg.de/wp-content/uploads/2022/04/tm_Webbanner_Image_Kombi_KHtm_230x60px_Aufschluss_220426.jpg 479w, https://vfmg.de/wp-content/uploads/2022/04/tm_Webbanner_Image_Kombi_KHtm_230x60px_Aufschluss_220426-300x78.jpg 300w" sizes="auto, (max-width: 479px) 100vw, 479px" /></a></div><div id="media_image-18" class="widget widget_media_image"><h3 class="widget-title">Unsere Partner</h3><a href="https://kristall-labor.de"><img width="2300" height="600" src="https://vfmg.de/wp-content/uploads/2023/01/nsmail.png" class="image wp-image-3060 attachment-full size-full" alt="" style="max-width: 100%; height: auto;" decoding="async" loading="lazy" srcset="https://vfmg.de/wp-content/uploads/2023/01/nsmail.png 2300w, https://vfmg.de/wp-content/uploads/2023/01/nsmail-300x78.png 300w, https://vfmg.de/wp-content/uploads/2023/01/nsmail-1024x267.png 1024w, https://vfmg.de/wp-content/uploads/2023/01/nsmail-768x200.png 768w, https://vfmg.de/wp-content/uploads/2023/01/nsmail-1536x401.png 1536w, https://vfmg.de/wp-content/uploads/2023/01/nsmail-2048x534.png 2048w" sizes="auto, (max-width: 2300px) 100vw, 2300px" /></a></div><div class="tribe-compatibility-container" > <div class="tribe-common tribe-events tribe-events-view tribe-events-view--widget-events-list tribe-events-widget" data-js="tribe-events-view" data-view-rest-url="https://vfmg.de/wp-json/tribe/views/v2/html" data-view-manage-url="1" data-view-breakpoint-pointer="c76f6c86-5208-4aea-b7bc-e331ea8fa747" > <div class="tribe-events-widget-events-list"> <script type="application/ld+json"> [{"@context":"http://schema.org","@type":"Event","name":"46.
