果洛龙洼金矿位于东昆仑造山带东段,华力西.印支期是最重要的成矿期。矿体受近东西向断裂控制,地-层为矿源层和隔挡层,对矿质进行圈闭,变质热液及岩浆提供热源和物质。成矿作用分为变质热液期和岩浆热液期,前者包括乳白色石英脉阶段（A）和含金石英黄铁矿阶段（B）,为主成矿期,后者对应石英硫化物再富集阶段（C）,起叠加改造作用。综合稳定同位素及包裹体的特征,从多因复成的角度探讨其成矿作用。稳定同位素反映成矿物质及流体为多来源。包裹体研究表明：B、C阶段发育3种包裹体：Ⅰ型水溶液包裹体、Ⅱ型水溶液-CO_2包裹体、Ⅲ型纯CO_2包裹体。B阶段发育的3种包裹体温度集中于260~360℃,Ⅰ型、Ⅱ型包裹体盐度分别为10.70%~22.69%和3.52%~12.42%,流体可能来源于变质热液,属变质热液期。C阶段发育Ⅰ型包裹体及少量Ⅱ型包裹体,温度集中于160~320℃,Ⅰ型、Ⅱ型包裹体盐度分别为15.90%~23.32%和10.62%~13.57%,成矿热液可能主要来源于岩浆热液,为岩浆热液期。矿床在变质热液期成矿,后期受到岩浆热液叠加改造,矿质进行再富集。因此,矿床具多大地构造阶段、多控矿因素、多成矿物质来源、多成矿作用及多成因类型,属多因复成矿床。

我们已完成了穿越准噶尔盆地及其周边地区的I-I、II-II、III-III、IV-IV和额敏—哈密剖面5条综合地球物理剖面。通过综合研究,初步了解准噶尔盆地及邻近地区的地球动力学问题:准噶尔盆地基底由北部的乌伦古地体和南部的玛纳斯地体组成。两者的分界为西西北方向的滴水泉—三个泉缝合线。其西部与北东向Dalbutte缝合带相连,东部与北西向的Cranamary缝合带相连。准噶尔盆地北部的乌伦古地体基底为双层构造,上层为泥盆系和下石炭统组成的褶皱基底,大致表现为北厚(3~5 km)、南薄(1~2 km)。缝合线以南的玛纳斯地体为单层基底,即新元古代结晶基底。准噶尔盆地地壳厚度为44~52 km,北薄南厚。周边山区地壳厚度高于盆地地区。盆地及邻近地区地壳分为上、中、下层,并且中地壳一般较薄。盆地地区的地壳存在多条深断裂。南北方向发育了6条主要深断裂,分别为红车、德伦山、石溪、呼图壁、彩南和阜康。这些断层倾角较大,向上延伸至上地壳下部,向下切入地壳基底界面。壳内水平构造和构造面无明显垂向断层,似有“开放断层”特征。这些断层是上地幔物质挤入地壳的良好通道。此外,该地区还有两条主要的横向深断层。一是北西西走向的滴水泉—三个泉深断裂,它向南倾斜,具有逆断层性质,可能会破坏滴水泉—三个泉缝合带。另一条是近东西向的昌吉—玛纳斯深断裂,向南倾斜,主要发育在中下地壳,具有逆断层性质。这些深断裂对盆地构造发育具有一定的控制作用。准噶尔盆地西部的莫霍面基本连续地延伸到了天山的莫霍面,并且后者的莫霍面深度明显大于前者。但是,盆地东部的莫霍面与博格达山脉的莫霍面并不连续。前者以叠加关系延伸到后者之下,表明盆地东部的地壳向博格达山脉俯冲。这有助于解释天山东部构造活动相对减弱而博格达山脉向北推高的构造地貌现象。周边准噶尔盆地具有挤压盆地山地构造耦合格局,尤其是南部边界东部博格达—准东盆地的山地盆地构造耦合。现在将准噶尔盆地与吐哈盆地分开的博格达山脉是年轻的、仍在上升的山脉。博格达山的隆升是印支运动以来多次推覆造山运动的反映,其现貌是新近纪以来新构造运动的结果。准噶尔盆地盖层发育经历了3个阶段:与天山和松潘—甘孜造山带形成有关的二叠纪—三叠纪前陆盆地阶段,区域压缩较弱的侏罗纪—早始新世陆内坳陷阶段,以及新近纪晚期以来与天山抬升有关的活化前陆盆地阶段。

BACKGROUND Although important for determining long-term outcome, pathologic stage of hepatocellular carcinoma (HCC) is difficult to predict before surgery. Current state-of-the-art magnetic resonance imaging (MRI) using gadoxetic acid provides many imaging features that could potentially be used to classify single HCC as pT1 or pT2. AIM To determine which gadoxetic acid-enhanced MRI (EOB-MRI) findings predict pathologic stage T2 in patients with solitary HCC (cT1). METHODS Pre-operative EOB-MRI findings were reviewed in a retrospective cohort of patients with solitary HCC. The following imaging features were examined: Hyperintensity in unenhanced T2-weighted images, hypointensity in unenhanced T1-weighted images, arterial enhancement, corona enhancement, washout appearance, capsular appearance, hypointensity in the tumor tissue during the hepatobiliary (HB) phase, peritumoral hypointensity in the HB phase, hypointense rim in the HB phase, intratumoral fat, hyperintensity on diffusionweighted imaging, hypointensity on apparent diffusion coefficient map, mosaic appearance, nodule-in-nodule appearance, and the margin (smooth or irregular). Surgical pathology was used as the reference method for tumor staging. Univariate and multivariate analyses were performed to identify predictors of microvascular invasion or satellite nodules. RESULTS There were 39 (34.2%;39 of 114) and 75 (65.8%;75 of 114) pathological stage T2 and T1 HCCs, respectively. Large tumor size (≥ 2.3 cm) and two MRI findings, i.e., corona enhancement [odds ratio = 2.67;95% confidence interval: 1.101-6.480] and peritumoral hypointensity in HB phase images (odds ratio = 2.203;95% confidence interval: 0.961-5.049) were associated with high risk of pT2 HCC. The positive likelihood ratio was 6.25 (95% confidence interval: 1.788-21.845), and sensitivity of EOB-MRI for detecting pT2 HCC was 86.2% when two or three of these MRI features were present. Small tumor size and hypointense rim in the HB phase were rega

R_w = 0.063 for 1130 ob- served reflections with I> 3σ(I) . The coordinated octahedra of Cu(Ⅱ) and tetrahedra of Zn(Ⅱ) via bridging Cl atoms form a single chain polynuclear complex. The Cu, Zn and bridging Cl atoms are located on the crystallographic symmetry plane m which is perpendicular to 2N and 2O donor plane.

本文通过H2O、NH4Cl和柠檬酸三种浸取剂分别浸取对赤泥中的Na+,并通过XRD分析了浸取前后赤泥中矿物组成的变化来研究拜耳法赤泥中Na+的浸出特性。结果表明,NH4Cl对赤泥中Na+的一次浸取率与赤泥经多次水洗的浸取率之和相同;柠檬酸对赤泥中Na+的一次浸取率可达到95.56%。从XRD图上发现NH4Cl可不破坏[Al6Si6O24]结构而浸出可溶性的Na+,而柠檬酸则会破坏[Al6Si6O24]结构使赤泥中Na+完全浸出。
