Submarine, Surface ship, Land-based (in development) [ 12] The 3M22 Zircon, [ 13] also spelled as Tsirkon ( Russian: Циркон, NATO reporting name: SS-N-33) [ 14] is a Russian scramjet -powered, nuclear-capable hypersonic cruise missile. Produced by NPO Mashinostroyeniya for the Russian Navy, the missile utilizes the ZS-14 launch platforms ...
Zircon (/ ˈ z ɜːr k ɒ n,-k ən /) [7] [8] [9] is a mineral belonging to the group of nesosilicates and is a source of the metal zirconium. Its chemical name is zirconium(IV) silicate, and its corresponding chemical formula is Zr SiO 4. An empirical formula showing some of the range of substitution in zircon is (Zr 1–y, REE y)(SiO 4) 1–x ...
Hadean zircon is the oldest-surviving crustal material from the Earth's earliest geological time period, the Hadean eon, about 4 billion years ago. Zircon is a mineral that is commonly used for radiometric dating because it is highly resistant to chemical changes and appears in the form of small crystals or grains in most igneous and metamorphic host rocks.
2.15–2.18. Cubic zirconia (abbreviated CZ) is the cubic crystalline form of zirconium dioxide (ZrO 2 ). The synthesized material is hard and usually colorless, but may be made in a variety of different colors. It should not be confused with zircon, which is a zirconium silicate (ZrSiO 4 ).
Myrmekite is a vermicular, or wormy, intergrowth of quartz in plagioclase. The intergrowths are microscopic in scale, typically with maximum dimensions less than 1 millimeter. The plagioclase is sodium -rich, usually albite or oligoclase. These quartz-plagioclase intergrowths are associated with and commonly in contact with potassium feldspar.
ZTR index. The ZTR index is a method of determining how weathered, [1] both chemically and mechanically, a sediment (or a corresponding sedimentary rock) is. The letters in ZTR stand for 3 common minerals found in ultra-weathered sediments: zircon, tourmaline, and rutile. Other minerals that can be used alongside the ZTR index are garnet ...
Zirconium dioxide ( ZrO. 2 ), sometimes known as zirconia (not to be confused with zircon ), is a white crystalline oxide of zirconium. Its most naturally occurring form, with a monoclinic crystalline structure, is the mineral baddeleyite. A dopant [clarification needed] stabilized cubic structured zirconia, cubic zirconia, is synthesized in ...
Yilgarn Craton. Basic geological regions of Australia, by age. The large brown region in the lower left of the continent constitutes the Yilgarn Craton. The Yilgarn Craton is a large craton that constitutes a major part of the Western Australian land mass. It is bounded by a mixture of sedimentary basins and Proterozoic fold and thrust belts.
