"Transformer"</h1> <p> by <a href="/user/Mineralogist1990/"><strong>Dmitry Tonkacheev</strong></a>, IGEM RAS, Moscow, Russian Federation </p> <div itemprop="description" class="hyphens"><p>Presented intergrowths of the infinite number of dark-brown sphalerite's and arborescent crystals of gold were synthesized using gas transport method at 850 centigrade degree during 20 days by Dmitry Chareev from the Institute of Experimental Mineralogy RAS in Chernogolovka city, Moscow Region while we were working on the project of Russian Scientific Fund in the Institute of Ore Geology, Petrology Mineralogy and Geochemistry RAS. <br>The main aim of this project was the determination of the maximum possible concentration and chemical state of some trace elements in the most aboundant sulfides, synthesized using different techniques, including in ZnS. We obtained crystals of Fe-bearing sphalerite with simultaneous incorporation of Cd, Mn, In, Se and Au. The concentration of gold reaches 3 000 ppm (0.3 wt.%). This is amazing for natural sphalerite. The next goal was in-depth-study of the influence of the presence of Se, In, Fe, Mn on Au concentration and also lattice parameter in ZnS. In this connection in the furnace-charge of Fe-bearing sphalerite, different admixtures were added in different combinations or severally.<br>According to LA-ICP-MS data Fe did not encourage Au annexation (73±1 ppm). The bulk of Au wire "boards" on the dark-brown phase surface in the form of fascination crystals (usually arborescent). Some of them looks like a weapon from the "Transformers" arsenal or parts of his armor. Also bright diamond luster of this creature makes our "Knight" even more ultra-modern. <br>Militiamen's profile was confirmed by twisted skeletal crystal on the transformer's head. It looks like ostrich plumage or horn, which were the main attribute in the plate armor of ancient warriors and indicated about their noble birth. Truly, it is a king of all sulfides.<br>The good news for us is the fact, that the coarsening of this bellicose subject is approximately 1-2 mm.<br>Thank you Tim Pashko and Pavel Martynov for using your equipment and assistance</p></div> <p> <a href="/photo-competition/2016/">Finalist in the EGU Photo Competition 2016</a> </p> </div> <div id="comments"> <form method="get" action="/login/"><input type="hidden" name="csrfmiddlewaretoken" value="MEH6Pk8vq9WkaR1w9Qz7BUmQr40qugf5cYnex6qn52z1zPj7AwjsWWWDe9Djz4qy"> <fieldset> <input type="hidden" name="next" value="/view/3791/"> <button type="submit" class="btn btn-default pull-right" data-username="">Login to Comment</button> </fieldset> </form> </div> </div> <div id="right"> <h4>Category</h4> <ul> <li><a href="/category/geochemistry-mineralogy-petrology-volcanology/">Geochemistry, Mineralogy, Petrology & Volcanology (986)</a></li> </ul> <h4>Location</h4> <div itemprop="contentLocation" itemscope itemtype="http://schema.org/Place"> <meta itemprop="name" content="Europe, Eastern Europe, Russian Federation"> <ul> <li><a href="/region/europe/">Europe (3874)</a></li> <li><a href="/region/eastern-europe/">Eastern Europe (457)</a></li> <li><a href="/region/russian-federation/">Russian Federation (224)</a></li> </ul> </div> <h4>Tags</h4> <ul> <li><a href="/tag/crystal-growths/">crystal growths (1)</a></li> <li><a href="/tag/sulphides/">sulphides (7)</a></li> <li><a href="/tag/gas-transport-method/">gas transport method (1)</a></li> <li><a href="/tag/experimental-mineralogy/">experimental mineralogy (1)</a></li> </ul> <h4>Colours</h4> <div id="colors" class="indent"> <a href="/color/000000/" title="#000000 - 32%"><svg width="24" height="24" viewBox="0 0 100 100" version="1.1" xmlns="http://www.w3.org/2000/svg"><circle cx="50" cy="50" r="45" stroke="#ccc" stroke-width="2" fill="#000000" /></svg></a><a href="/color/330000/" title="#330000 - 16%"><svg width="24" height="24" viewBox="0 0 100 100" version="1.1" xmlns="http://www.w3.org/2000/svg"><circle cx="50" cy="50" r="45" stroke="#ccc" stroke-width="2" fill="#330000" /></svg></a><a href="/color/333300/" title="#333300 - 12%"><svg width="24" height="24" viewBox="0 0 100 100" version="1.1" xmlns="http://www.w3.org/2000/svg"><circle cx="50" cy="50" r="44" stroke="#ccc" stroke-width="2" fill="#333300" /></svg></a><a href="/color/333333/" title="#333333 - 5%"><svg width="24" height="24" viewBox="0 0 100 100" version="1.1" xmlns="http://www.w3.org/2000/svg"><circle cx="50" cy="50" r="30" stroke="#ccc" stroke-width="2" fill="#333333" /></svg></a><a href="/color/666666/" title="#666666 - 4%"><svg width="24" height="24" viewBox="0 0 100 100" version="1.1" xmlns="http://www.w3.org/2000/svg"><circle cx="50" cy="50" r="28" stroke="#ccc" stroke-width="2" fill="#666666" /></svg></a><a href="/color/663300/" title="#663300 - 3%"><svg width="24" height="24" viewBox="0 0 100 100" version="1.1" xmlns="http://www.w3.org/2000/svg"><circle cx="50" cy="50" r="26" stroke="#ccc" stroke-width="2" fill="#663300" /></svg></a> </div> <hr> <h4>Image properties</h4> <p class="indent"> <a href="/width/2596/" itemprop="width">2596</a> × <a href="/height/3700/" itemprop="height">3700</a> px;
