萤石

• For thirty years , the institute has been engaged in geological prospecting for alunite , illite , pyrite , bentonite , fluorite , phosphate rock , sericite etc , has completed and submitted more than 70 geological reports
  该院对明矾石、伊利石、硫铁矿、膨润土、萤石、磷矿、绢云母等矿进行了综合找矿，综合评价，先后提交各类地质报告70余份。
• Don edwards showed me some new fluorite from a single pocket find at the crich quarry in derbyshire - excellent for derbyshire fluorite and , more unusually , fluorescent ( possibly do to organic inclusions )
  唐?爱德华兹从一个单独的袋子找出了一些德比郡克赖奇采石场新的萤石向我展示了，都是出色德比郡萤石，而更不寻常这些东西发萤光（可能含有有机包裹体） 。
• Thin films with thickness of 0 . 31m and 0 . 36m respectively on si substrate , have been successfully prepared by a sol - gel spin coating method . cubic nanocrystals can be obtained at relatively low sintering temperature with an average grain size of about 47 nm and 51 nm respectively . the aluminia - doped scsz thins film are the same dense as the scsz thin films . however , there are a small amount of pinholes found in the microstructure of the titania - doped scsz films
  0 . 70固体电解质纳米晶薄膜。烧结实验结果表明，两种薄膜均在650以上开始晶化，温度越高，晶化越完全，在800可完全晶化所得纳米晶颗粒呈纯的萤石结构立方相铝和钛掺杂的纳米晶颗粒的平均大小分别为47和51nm 。

• The wall rock of ore - bodies is the siliceous dolostone and alkaline volcanic rock ( trachy andesite ) in the yinachang deposit . based on the shape of ore - bodies and the structure and texture of ores , the deposit was identificed as synsedimentary with wall rocks . there occurred ree minerals , such as bastnaesite , monazite and allanite , associated with apatite and fluorite with ree contents to a certain extent
  矿体产出形态和矿石的结构构造等均显示矿体与赋矿地层同沉积特征；出现独立矿物氟碳铈矿、独居石及褐帘石，磷灰石、萤石、菱铁矿等矿物中也含有一定量的稀土，沿矿体走向和垂向稀土元素变化不大。
• There is a close relation between mesozoic tectonic evolution , fluid evolution , petrogenesis and mineralization in the manzhouli - e ' erguna region in the northeast of the northern orogenic belt , china , and three evolution stages of the mesozoic tectonic - fluid - petrogenetic and metallogenetic system are proposed out : 1 ) acompanied by ree and cu mineralization , the calc - alkaline volcanic rocks and mantle - crust mixed type granite occurred under the regional tension tectonic background caused by the mongolia - okhotsk residual ocean that was closing in scissors form in the early - middle jurassic . 2 ) acompanied by pb , zn and ag mineralization , the calc - alkaline and alkaline volcanic rocks occurred under the regional shear - compression tectonic background in the late jurassic . 3 ) acompanied by u , f , pb , zn and ag mineralization , the caic - alkaline and alkaline volcanic rocks occurred under the regional tension tectonic background in the early cretaceous
  摘要本文讨论了北方造山带东北段满洲里额尔古纳地区及其毗邻区中生代构造流体成岩成矿系统及其演化的三个不同阶段： 1 )早中侏罗世张性“似裂谷环境”下所形成的中基性碱性火山岩、同熔性花岗岩及深源流体活动形成的稀土矿床和斑岩性铜铝矿床； 2 )晚侏罗世挤压剪切环境下所形成的酸性火山岩、斑岩类及深源流体活动所形成的铅锌银矿床； 3 )早白垩世张性环境下所形成的基性碱性火山岩及深源流体活动所形成的铀矿床、金银矿床及萤石矿床。
• The gangue minerals are mostly carbonating minerals , fluorite , barite , celestite and so on ; the rock alteration is slightly silicified , carbonated , baritizated , celestited , which is low - temperature alteration . because of continual downgoing extrusion from india plate to euro - asian plate , there are some thrusting nappe structures in lanping basin related to the orogens on the two sides
  矿床中矿石矿物发育典型的中低温热液成因的矿物组合，如黝铜矿系列、方铅矿、黄铜矿等，脉石矿物主要为碳酸盐类矿物、萤石、重晶石、天青石等；围岩蚀变主要发育弱硅化、碳酸盐化、重晶石化、天青石化等低温蚀变组合。
