金红石的

Major conclutions from this study can be summarized as following:1. On mineralogy, rutiles, apatites, epidotes and vein minerals from UHPM rocks were firstly and systematically studied, by detailed petrography and mineral-chemistry investigation, some mineral or mineral assemblage with special composions or texture were firstly found in UHPM rocks from Sulu-Dabie, for example, corrudum, magnesite, high-Ti biotite and garnet were found as inclusions in rutiles from eclogites, Nb-Fe rutile and zoned Si-Y apatite were found in gneiss, epidote / allanite with euhedral zones like magmatic genesis were found in elogites and gneiss, a lot of minerals with high REE, HFSE, LILE and volatiles were found in veins of gneiss.

在矿物学方面，首次较为系统地研究了超高压变质岩中的金红石、磷灰石、绿帘石等副矿物，并通过详细的岩相学和矿物化学研究，首次在苏鲁-大别超高压变质岩中发现了一些具有特殊成分/结构的矿物或矿物组合，如在榴辉岩金红石中发现了刚玉、菱镁矿、高钛黑云母和石榴石矿物包裹体，在片麻岩中发现了Nb-Fe金红石和具有自形环带结构的高Si-Y磷灰石，在榴辉岩和片麻岩中发现了具有类似岩浆成因的自形生长环带结构的绿帘石/褐帘石，在片麻岩的脉体中发现了大量富含稀土元素REE、高场强元素HFSE(Nb、Ta、Zr、Ti)、大离子亲石元素LILE(K、Th、U、Sr、Ba)，以及挥发性组份(CO_2、F、P、S)的特殊矿物，丰富并提升了超高压变质岩的矿物学研究。2。

TiO2 is known to exist in three distinct structures: two tetragonal phase for anatase and rutile and a third orthornombic phase for brookite. Rutile has the most stable structure and physical and chemical properties. In rutile structure oxygen cavities move quickly so that rutile has better gas sensing respond and become a chief material use for oxygen gas sensors.

其中金红石结构是最为稳定的晶型，不但具有最为稳定的物理、化学性能，而且在金红石结构中，晶格中氧空位的迁移率较高，因而TiO_2金红石结构气敏响应效应较好，从而使金红石结构TiO_2氧化物材料成为氧敏传感器的首选材料之一。

Study using infrared microtechnique reveals three types of fluid inclusions in rutile:Ⅰ-type aqueous inclusions,Ⅱ-type CO_2-H_2O inclusions and Ⅲ-type CH_4 inclusions. Primary and pseudosecondary type Ⅰ inclusions, as well as Ⅱ-type fluid inclusions, having a range of pressure between 0.6 and 1.3 GPa, were trapped during the amphibolite-facies retrogression stageof eclogites, suggesting that fluids related to rutile mineralization originated from water released during retrograded metamorphism of eclogites.

利用红外显微镜对金红石进行的流体包裹体研究表明，金红石中主要存在三类流体包裹体，即Ⅰ型H2O溶液包裹体、Ⅱ型CO2-H2O包裹体和Ⅲ型CH4包裹体，其中I型原生和假次生流体包裹体和Ⅱ型流体包裹体反映出的压力范围为0.6～1.3 GPa，与榴辉岩角闪岩相退变质作用的压力相当，说明与这类金红石形成有关的变质流体源于榴辉岩退变质作用所释放的水。
