中亚造山带岩浆铜镍硫化物矿床深部找矿：以红旗岭铜镍矿床为例

为了对中亚造山成矿带东段南缘红旗岭岩浆型铜镍硫化物矿床深部（500～1 000 m）隐伏矿体进行成矿预测,采用高精度重力和2.5维人机交互式反演方法,对含矿性较好的镁铁质—超镁铁质岩体（如#1、#3及新#3岩体）进行底部含矿性研究。结果表明：高精度重力异常开展不同高度上延并结合垂向一阶导数等数据处理,可有效地厘定深部隐伏岩体空间展布;2.5维人机交互式反演方法可以识别深部微弱的矿致异常,推测研究区#3岩体埋深700～1 100 m存在5个脉状盲矿体。经钻探验证,成功发现32 259 t]镍矿（矿石平均品位达0.36%）,其中②号矿体为最厚矿体,见矿深度为700～1 100 m,镍矿平均品位为0.39%,储量达27 433 t。

NONHYDROSTATIC NUMERICAL SIMULATION FOR THE “96.8” EXTRAORDINARY RAINSTORM AND THE DEVELOPING STRUCTURE OF MESOSCALE SYSTEM*

During the period of 3—5 August 1996(for short "96.8"),an extraordinary rainstorm event occurred in Henan,Hebei and Shanxi Provinces in China,resulting in severe flood catastrophe.Synoptic analyses indicated that the stable gross col field and the interaction between a northward moving typhoon(down into low pressure)and its east lateral Pacific subtropical high were the large-and meso-scale circulation conditions of the "96.8" extraordinary rainstorm.The mesoscale typhoon-low and its specific dynamical and thermodynamical structures were directly related to this rainstorm event.The nonhydrostatic version of mesoscale numerical model MM5 was used to conduct investigation of numerical simulation for this case.The simulation with the full physical processes of nonhydrostatic version MM5 was basically possessed of a capability to reproduce the genesis,development and evolution of the large-scale and meso-α scale synoptic systems.The simulative results using a two-way interactive nesting procedure revealed that the typhoon-low was possessed of an intensive coupled mechanism between the dynamical and thermodynamical fields,namely,the developing typhoon-low was possessed of a structure of the.cyclonic vorticity column with warm center and high humidity,the vorticity column on the lower levels was the moist convective instability and negative moist potential vorticity structure:the intensive ascending vertical motion and the intense divergence on upper levels and intensive convergence on the lower levels as well as the development of the convective cloud cluster were intercoupling:the intense southern wind jet companied by the typhoon-low was not only the interaccompanying and intercoupling condition of the development and maintenance of the typhoon-low and convective cloud cluster,but also was the transportable belt of the moisture source and heat energy of the "96.8" extraordinary rainstorm.The analysis of simulative results of precipitation indicated that the distribution of the rainfall belt and rainfall rate was basically consistent with that of the observation in spite of some rainfall centers less or larger than those of the observation for coarse or fine mesh domain,respectively.
