在塔里木地台北缘断隆带上,广泛分布早元古代变质地层和同构造期蓝石英二长花岗岩.该区西部1140km~2范围内,已发现金及多金属水系沉积物综合异常20多处.其中大、小金沟金矿化区异常显示完整,具有典型性和代表性.根据该异常区原生金矿化地质特征、成矿控制条件、成矿作用与地质作用的关系,查证了本区曾经历了变质热液、岩浆热液和混合古地热水多期成矿作用的演化过程.

Blue chaleedony is one of the most precious gemstones in Taiwan, The most popular imitations of blue chalcedony in Taiwan market are dyed chalcedony, dyed quartzite and blue opal. Recentlywe checked one of the new imitations and found its RI and SG very close to blue chalcedony but the spectrum of FTIR the same as glass. With the analysis of EDXRF we make sure it is a man-made glass.

蓝玉髓是台湾最珍贵的宝石之一,它产于台湾东部海岸山脉一带。由于几十年来不断地采掘使得产量大减,在供不应求的情况下,各种模仿品应运而生。在台湾市场上最常见的模仿品有染色蓝玉髓、染色蓝石英岩及蓝色蛋白石。最近我们鉴定到一些新的模仿品,其折射率及比重非常接近蓝玉髓,但红外光谱显示与玻璃相同,以EDXRF分析,认定是人造玻璃。

Precise age determination of the Qingir gray gneisses from the northern margin of the Tarim Basin is important for our understanding of crustal evolution of the Tarim Craton. The present SIMS zircon U-Pb dating yielded an age of 2565±18(2σ) Ma for the Qingir gray gneiss, which is the dominant constituent of the Tuokelakebulake complex in this region. The new result is comparable with zircon U-Pb age of blue-quartz-bearing granite from the central section of region of Kuluketage. It indicates that they are all...

Precise age determination of the Qingir gray gneisses from the northern margin of the Tarim Basin is important for our understanding of crustal evolution of the Tarim Craton. The present SIMS zircon U-Pb dating yielded an age of 2565±18(2σ) Ma for the Qingir gray gneiss, which is the dominant constituent of the Tuokelakebulake complex in this region. The new result is comparable with zircon U-Pb age of blue-quartz-bearing granite from the central section of region of Kuluketage. It indicates that they are all Neo-Archean magmatites with TTG component. Together with the literature data, including a Sm-Nd isochron age of 3263±126 Ma (2σ), with ε_ Nd (t)=+3.2±0.7, for amphibolite enclaves in the gray gneisses from the Qingir (Hu and Rogers,1992), and several Nd model ages (T_ DM ) of 3200 to 2600 Ma for gneisses, granites, and schists from the area (Hu et al., 2000;Dong et al., 1999; Feng et al., 1998), it strongly suggests that the basement rocks in the northern margin of the Tarim Basin were formed in the Meso- to Neo-Archean times. However, all these Archean rocks have undergone post-Archean tectonic activities and metamorphism, which are witnesses by zircon U-Pb ages of ~2300 Ma and ~2000 Ma for the Qingir gray gneiss, ~2000 Ma for granitic gneiss intruded into the Qingir gray gneisses (Gao et al., 1993; Guo et al., 2003), and ~1800 Ma for an amphibolite from Tiemenguan (Guo et al., 2003). K-Ar age study also reveals Neo-Proterozoic thermal events in the northern margin of the Tarim Basin. ~ 40 Ar/ ~ 39 Ar plateau ages and laser ~ 40 Ar/ ~ 39 Ar isochron ages for hornblendes, biotites and muscovites from various metamorphic rocks in different parts of the northern Tarim range from 850 Ma to 500 Ma. These ages indicate that the northern Tarim probably underwent diachronous uplift in different regions during the late Neoproterozoic to early Paleozoic (Hu et al., in press).

获得塔里木盆地北缘辛格尔灰色片麻岩的可靠形成年龄对研究塔里木克拉通地壳构造演化是十分重要的。本研究应用SIMS锆石U-Pb定年,获得了塔里木北缘辛格尔南托格拉克布拉克杂岩中占主要成分的灰色片麻岩的形成年龄为2565±18(2σ)Ma,这一研究结果说明了辛格尔地区的灰色片麻岩和库鲁克塔格中部的蓝石英花岗岩等均为新太古代晚期形成的TTG组份的岩浆岩。综合已有的研究结果,如灰色片麻岩中以残留包体形式存在的斜长角闪岩的Sm-Nd等时线年龄=3263±126Ma(2σ),εNd(t)=+3.2±0.7(Huetal.,1992),以及塔里木北缘范围内各种片麻岩、片岩和各种花岗岩的Nd模式年龄(TDM)分布在3200~2600Ma范围内(冯新昌等,1998;董富荣等,1999;Huetal.,2000),完全可以确认塔里木盆地北缘普遍存在中—新太古代基底。但是,它们遭受了古元古代构造、变质和岩浆活动的强烈改造。辛格尔灰色片麻岩中~2300Ma、~2000Ma和片麻状花岗岩的~2000Ma锆石U-Pb年龄(高振家等,1993;郭召杰等,2003),以及铁门关斜长角闪岩中的锆石U-Pb年龄~1800Ma(郭召杰等...
