Exempel på hur man kan använda ZIRCON i en mening

• The economy of Senegal is driven by mining, construction, tourism, fishing and agriculture, which are the main sources of employment in rural areas, despite abundant natural resources in iron, zircon, gas, gold, phosphates, and numerous oil discoveries recently.
• Besides zircon, zirconium occurs in over 140 other minerals, including baddeleyite and eudialyte; most zirconium is produced as a byproduct of minerals mined for titanium and tin.
• Natural resources in the Flowery Branch area include: gray marble, marble, clay, granite, graphite, limestone, iron ore, manganese, pegmatite, mica, beryl, quartzite, zircon, lead, copper, silver, and gold as known by the local Gold Hill Mine and regional popularity of The Hall County Gold Belt prospected during the Georgia Gold Rush.
• This is because, when silica is free in the system (silica-saturated/oversaturated), zircon is the dominating phase, not baddeleyite.
• The thermal history of a basin is usually calibrated using thermal indicator data, including vitrinite reflectance and fission tracks in the minerals apatite and zircon.
• Monazite also shares many structural similarities with; zircon, xenotime, scheelite, anhydrite, barite, and rhabdophane.
• There is coal mining, but gold and silver mines are also found in Chungcheongnam-do, as is Monazite (a rare thorium bearing mineral) and zircon.
• The jars at Site 1 (using detrital zircon geochronology) were determined to have been transported to their current location from a presumed quarry eight kilometers away.
• Naracoopa was the chief bulk fuels port and depot and is the site of a mineral sands deposit from which rutile, zircon and ilmenite were extracted between 1968 and 1977.
• Sand mining for monazite (zircon, uranium and thorium) between the World Wars damaged the environment further.
• GCHQ therefore decided to produce a UK-designed-and-built signals intelligence satellite, to be called Zircon, a code-name derived from zirconium silicate, a diamond substitute.
• A recent study (de Grave, 2015) aimed to fill this gap by presenting the initial zircon U/Pb ages of the volcanic basement and thermochronological ages for the rocks of Kunashir Island, thus establishing a definitive temporal framework for their emplacement and subsequent exhumation.
• It is an extinct volcano dating to the Neoproterozoic and is approximately 704 million years old (+/- 4 million years) as dated using the U-Pb zircon crystal geochronology method.
• It is commonly associated with zircon, monazite, gadolinite, fergusonite, uraninite, yttrialite and pyrochlore.
• However, recent detrital zircon geochronology results have suggested that the Jackpile Sandstone Member is part of the Burro Canyon Formation.
• It occurs in association with columbite, zircon, monazite, uraninite, aeschynite, magnetite, albite, topaz, beryl, garnet, muscovite and biotite.
• Iron ore, rutile (titanium oxide) and zircon are mined from the dunes close to the lagoon by Richards Bay Minerals, part of the Rio Tinto Group.
• These minerals, mostly titanium (ilmenite), zircon, and rutile were recovered from beach sands by the Buckman and Pritchard Mining Company.
• Accessory minerals include chlorite, apatite, zircon and magnetite, with rare biotite, hornblende or pyroxene.
• It occurs as a rare component within ultramafic nodules in kimberlites in association with olivine, enstatite, chrome diopside, chromian pyrope, chromian spinel, ilmenite, perovskite, zircon, diamond, omphacite, rutile, carbonates and micas.
