Characteristics of zircons revealed by cathodeluminescence images from rutile ores with different colors are incredible similar.

从红色和黑色金红石矿中的锆石阴极发光图像来分析，尽管上述三个样品的矿物组合、金红石的颜色、产状及形成P—T条件有所不同，但其中锆石的特征及年龄结果却有惊人的相似，甚至完全相同。

Combined with previous studies, we suggest that the 1100-2200 Ma zircons perhaps originate from the China North Craton, while the zircons of 520 Ma may stem from Jiamusi massif.

Based on the interior structure of zircons from the ore-bearing Longwang gabrro intrusion and the results of CL analysis, the authors performed in-situ zircon U-Pb dating by means of LA-ICP-MS and, as a result, obtained reliable age data.

Therefore, the formation of the first episode of metamorphic zircons is correlated with fluid activity during the progressive high-pressure eclogite-faeies metamorphism.

This article discussed a superficial nanometer processing to the zircaloy corrosion resistance performance influence. For a surface nanometer and the ultra finer organization's zircaloy, its corrosion property influence factor not only includes the grain size, but also includes the alloy composition,the oxide film organization and the nature, the heat treatment technique, the surface condition, chemistry of reactor coolant, temperature of reactor coolant , heat flux through the cladding, irradiation effects and so on.

对于具有表面纳米及超细晶组织的锆合金来说，其腐蚀性能的影响因素不仅仅包括晶粒尺度，还包括合金成分、氧化膜的组织与性质、热处理工艺方法、表面状态、反应堆水化学、水冷却剂温度、通过包壳锆合金的热通量密度、辐照效应等等。

Of the five stages deformation, the exact ages of the (2) and (3) were determined by 40Ar/39Ar method as 290 and 259 Ma respectively.2. New results on the metamorphic belts and associated metamorphism of the Xiaopu metamorphic rocksBased on detailed microtextural observations and occurrence of typical metamorphic minerals, five metamorphic belts in the Xiaopu metamorphic rocks are identified. From the north to the south, they are biotite belt, garnet belt, staurolite belt, andalusite belt, and sillimanite belt. I suggested that the metamorphic belts occurred in the Xiaopu area belongs to the high temperature/low pressure series, may have resulted from the later Permian crust extension at ca. 290 Ma.3. I suggest that there may have been a Carboniferous backarc basin along the southern slope of the Harlik Mountain.Detrital Zircon SHRIMP U-Pb dating indicated that the sedimentary age of the Julideneng formation lithic sandstone must be later than late Devonian, most likely is Carboniferous rather than previously thought Precambrian. Analyses on its geologic setting, location of provenance, and sedimentary environment suggest the Carboniferous strata may form in a lagged backarc basin bounded by backarc uplifts.5. Reconstruction of the post-Paleozoic tectonic evolution history of the Harlik MountainThe tectonic evolution of Harlik mountains since the Paleozoic were reconstructed as followings:(1) arc-affinity magmative activities occurred during the middle-Ordovician to early-Silurian;(2) the middle-Silurian to late-Devonian was a back-arc uplift stage;(3) back-arc extension featured the Carboniferous period;(4) post-collisional extension and/then compression during Permian;(5) at the Mesozoic, differential uplift developed; and (6) the late Cenozoic is the intra-continental re-orogen stage.6. Primary estimation of the crust shortening is madeThe folded pre-Mesozoic strata were used to estimate crust shortening along the Harliknanshankou-Koumenzi, Shichengzi-Baishitou, and Qincheng-Xiaopu sections. Their shortening ratios are 16.2%, 19.8%, and 20.1% respectively corresponding crust shortening are 4.3, 9, and 11.3 km.

SHRIMP U-Pb concordia ages of the cores of rounded zircons are 620 and 219 Ma, suggesting that the parental magma for the quartz diorite porphyry may have been derived from partial melting of basement materials of the South China block that had been modified by ultrahigh-pressure metamorphism.

具有细微震荡环带岩浆锆石的SHRIMP U-Pb年龄(117.7±1.6 Ma)显示该石英闪长斑岩体的形成时间为早白垩世；浑圆状锆石核部SHRIMP U-Pb谐和年龄为620 Ma和219 Ma，这表明该石英闪长斑岩的母岩浆可能起源于经历了超高压变质作用改造的华南地块基底物质的部分熔融。
