Comprehensive Summary Herein,we have developed a strategy of Rh(III)-catalyzed C—H activation of N-nitrosoanilines and iodonium ylides to construct novel tetralydrocarbzol-4-one scaffolds,which provided valuable templates for sequential C—H functionalization such as alkylation,alkenylation,amidation and(hetero)arylation at C^(5)-position of tetralydrocarbzol-4-one with different coupling ***-scale synthesis and further transformations of tetralydrocarbzol-4-one derivatives to Ondansetron and its analogues demonstrated the utility of this protocol,which enabled the concise and diverse construction of biologically active molecules.

The Berezitovoe deposit is a large-sized Au-Ag-Zn-Pb deposit in the east of the SelengaStanovoi superterrane, Russia. Au-Ag orebodies are hosted by tourmaline-garnet-quartz-muscovite metasomatic rocks; Zn-Pb orebodies are hosted by granodiorites, porphyritic granites and tourmalinegarnet-quartz-muscovite metasomatic rocks. These orebodies are surrounded by wall rocks dominated by the Tukuringra Complex granodiorites, porphyritic granites, and gneissic granodiorites. The alteration includes silicification and garnet, sericitization chloritization, carbonatization and kaollinization. LA-ICP-MS U-Pb zircon dating indicates that the gold mineralization can be divided into two stages in the Berezitovoe polymetallic gold deposit（at 363.5 ± 1.5 Ma, and133.4± 0.5）.Hornblende-plagioclase gneisses of the Mogocha Group in the study area underwent Paleoproterozoic metamorphism（at 1870 ± 7.8 and 2400 ± 13 Ma）, gneissic granodiorite of the Tukuringra Complex yields a late Paleozoic magmatic age（at 379.2 ± 1.1 Ma）,and subalkaline porphyritic granitoid of the Amudzhikan Complex yield late Mesozoic magmatic ages（133-139 and 150-163 Ma）. Granodiorites of the Tukuringra Complex in the study area have high concentrations of SiO_2（average of 60.9 wt%）, are aluminum-oversaturated（average A/CNK of 1.49）, are enriched in the large ion lithophile elements（e.g.,K, Rb, and Ba）, U, Th, and Pb, are depleted in high field strength elements（e.g., Ta, Nb, and Ti）, and have slightly negative Eu and no Ce anomalies in chondrite-normalized rare earth element *** inclusions from quartz veins include three types： aqueous two-phase, CO2-bearing three-phase,and pure CO2. Aqueous two-phase inclusions homogenize at 167℃-249℃ and have salinities of 4.32%-9.47% NaCl equivalent, densities of 0.86-0.95 g/cm^3, and formed at depths of 0.52-0.94 km. In comparison, the CO2-bearing three-phase inclusions have homogenization temperatures of 265℃-346℃,salinities of 7.14%-11.57% NaCl equivalent, and total

黑龙江省上马场金矿床位于兴安地块东缘白乃庙-多宝山成矿带东部,是区内浅成低温热液型矿床的典型代表,龙江组粗面岩为主要容矿围岩,矿化以石英-碳酸盐脉形式产出。文章通过对矿区龙江组火山岩岩石地球化学分析和LA-ICP-MS锆石U-Pb测年,讨论了火山岩形成的构造环境与成岩成矿时代。岩石地球化学分析结果表明火山岩具有相同的微量元素特征,属于高钾钙碱性-钾玄岩系列,富集轻稀土元素和大离子亲石元素(如Rb、Ba、Th、K),Eu弱负异常,亏损高场强元素(Nb、Ta、Ti)。LA-ICP-MS锆石U-Pb测年结果显示,与成矿关系密切的粗面岩和流纹岩的锆石加权平均年龄分别为(123.4±2.1)Ma和(123±3.7)Ma,为早白垩世火山作用的产物。结合东北地区构造演化特征,认为上马场火山岩属于同源岩浆演化的不同产物,形成于蒙古-鄂霍茨克洋闭合机制下后碰撞伸展背景,正是这种伸展背景为区域大规模岩浆活动提供了足够的能量和空间,以金为代表的金属元素开始大量富集,形成了上马场金矿床。

下嘎来奥伊铅锌矿位于黑龙江省西北部,大地构造位置位于额尔古纳地块额木尔山隆起带南缘与大兴安岭火山岩带北缘交切部位的西段。矿体主要产于中酸性浅成侵入岩与新元古界—下寒武统倭勒根群吉祥沟组大理岩接触带,是一个以铁、铅、锌、钼矿为主的矽卡岩型矿床。通过野外工作和室内观察将其成矿期划分为2期5个阶段:(1)矽卡岩期:干矽卡岩阶段、湿矽卡岩阶段(形成富集的磁铁矿)、氧化物阶段(形成少量辉钼矿),(2)石英-硫化物期:早硫化物阶段(形成部分辉钼矿)、晚硫化物阶段(主要形成闪锌矿、方铅矿等铅锌硫化物)。结合成矿地质背景、矿区物化探特征,得出成矿控制因素为:(1)吉祥沟组大理岩及片岩在成矿过程中提供了部分成矿物质,(2)花岗斑岩、花岗闪长岩、细粒花岗岩等中酸性岩体在侵入过程中提供了成矿物质和能量,(3)矿区中部复式褶皱构造及北东向和北西向断裂是区内的主要控矿构造。在GIS平台上开展综合信息成矿预测,共圈出2处找矿预测区,指出了今后的找矿方向。这些认识对矿区及外围找矿工作具有重要的指导意义,为进一步开展深部找矿和相关理论研究提供了重要依据。
