个旧锰结核矿床地质地球化学与成因初步研究

个旧锰结核矿床产在锡石-多金属硫化物矿田顶部的第四系砂锡矿之中。从矿床地质产状、化学组成、微量元素、稀土元素、矿物组合等方面进行了讨论，认为个旧锰结核属于异地海相成因，后经搬运沉积在第四系砂锡矿之中；与中太平洋海山CAD19锰结核的物质组成和微量元素进行对比，表明个旧和CAD19锰结核有相类似的稀土模式，相对富集轻稀土，并出现明显的Eu负异常和Ce的正异常。

楚雄龙岗地区超级不整合与金成矿

龙岗地区陇川运动-华力西运动间造成整个古生代地层缺失，中上三叠统直接覆于下元古界哀牢山岩群、大红山岩群等基底岩系之上，本文称为“超级不整合”。华力西期-喜马拉雅期历次地壳事件在“超级不整合”接触带形成“矿质”的“浪淘砂”式、叠次‘堆积’作用，对该区金成矿有决定性作用，先后发现小水井与大龙潭两个典型金矿床。前者为“地下水热卤水溶滤中低温热液蚀变角砾岩微粒浸染型金矿床”，可类比为“卡林型”；后者为“原生沉积地下热水溶滤中低温热液蚀变砂砾岩微粒-粗粒型金矿床”，为该区首次发现的新类型。     

镇康芦子园铅锌矿床特征及成因

芦子园铅锌矿产于镇康复背斜核部寒武系沙河厂组大理岩、板岩、片岩地层中，沿背斜轴部产生的断层及层间破碎带是主要的容矿构造，成矿物质来源于地层、酸性及基性岩浆热液，矿床成因为沉积-热液改造叠生型铅锌矿床。

Influence of the Kunlun Mountain Ms8.1 Earthquake on Horizontal Crustal Deformation in the Sichuan and Yunnan Area

In order to track the space-time variation of regional strain field holistically(in a large scale) and to describe the regional movement field more objectively,the paper uses a nonlinear continuous strain model focused on extracting medium-low frequency strain information on the basis of a region with no rotation.According to the repeated measurements(1999～2001～2004) from GPS monitoring stations in the Sichuan and Yunnan area obtained by the Project of "China Crust Movement Measuring Network",and with the movement of 1999～2001(stage deformation background) as the basic reference,we separated the main influencing factors of the Kunlun Mountain M-S8.1 earthquake in 2001 from the data of 2001 and 2004,and the results indicate:(1) the Kunlun Mountain M-S8.1 earthquake has a discriminating effect on the Sichuan and Yunnan area,moreover,the deformation mode and background had not only certain similitude but also some diversity;(2) The movement field before the earthquake was very ordinal,while after the earthquake,order and disorder existed simultaneously in the displacement field;The displacement quantities of GPS monitoring stations were generally several millimeters;(3) The principal strain field before earthquake was basically tensile in an approximate EW direction and compressive in the SN direction,and tension was predominant.After the earthquake,the principal strain field in the Sichuan area was compressive in the EW direction and tensile in the SN direction,and the compression was predominant.In the Yunnan area,it was tensional in the NE direction and compressive in the NW direction,and tension was predominant;(4) The surficial strain before the earthquake was dominated by superficial expansion,the contractive area being located basically in the east boundary of Sichuan and Yunnan block and its neighborhood.After the earthquake,the Sichuan area was surface contractive(the further north,the greater it was),and south of it was an area of superficial expansion.Generally speaking,the Kunlun Mountain M-S8.1 earthquake played an active role in the accumulation of energy in the Sichuan and Yunnan area.Special attention shall be focused on the segment of Xichang-Dongchuan and its neighborhood.     

Corresponding Relation Between the Space-time Evolution of Seismic Apparent Strain and the Region of Strong Earthquakes in Yunnan

On the basis of our predecessors' research,we study the distribution and the space-time evolution characteristics of the seismic apparent strain field in Yunnan since the 1970's using the seismic data of Yunnan and its surrounding areas.The result shows that there is a rather strong corresponding relationship between the anomaly region of seismic apparent strain and strong earthquakes.In the nine earthquakes studied,anomaly areas of seismic apparent strain had appeared before eight earthquakes,including five occurring in the anomaly region and three on the edge.Finally,the investigative result is demonstrated primarily.     

MM5中尺度非静力模式对云南省降水预报检验

根据MM5／V3中尺度非静力模式数值预报结果，检验了该模式在云南2001年汛期（6－10月）的降水预报效果。结果表明，MM5模式降水预报对云南大部分地区的小雨有较高的TS评分，对于全省性大雨过程，MM5模式24小时降水预报的TS评分高于同期预报员的主观预报，但对暴雨及以上量级的降水预报，模式结果不太理想。     

遥感技术在云南中甸地区煤炭资源调查中的应用

以卫星遥感技术为主要手段,通过遥感地质解译,结合适量的野外调查,综合常规地质资料分析,认为云南中甸地区的含煤目的层为新第三系上新统和第四系更新统。并对该区新生代盆地的形成机制及煤层聚集、赋存规律进行了总结,圈定了5个含煤远景区,为该区进一步进行煤炭资源勘探提供了靶区和基础资料,对解决滇西北严重缺煤的现状有一定的实际意义。
