2Graduate School of Chinese Academy of Sciences, Beijing 100049, ChinaAbstract: Two sets of dehydrationmelting with a natural solid amphibolite(56vol.% hornblende, 43vol.% plagioclase), collected from the DabainengLeyu profile in the southern Ailaoshan orogenic belt, Honghe County, Yunnan Province, have been carried out in multianvil apparatus(YJ3000t and JL3600t) at 1035 GPa and 950 ℃ for 20300 h. One is keeping the temperature at 950 ℃ and the annealing time of 100 h, varying the pressure (1035 GPa). The other is keeping the pressure at 30 GPa and temperature at 950 ℃, varying the annealing time (20300 h). The products are inspected with microscope and electron probe.

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。
