海月构造带东三段滩坝砂分布及成藏主控因素分析

辽河滩海地区海月构造带东三段沉积期,三角洲前缘砂体受湖岸流和波浪的改造,形成了一系列滩坝砂沉积,细分为滩砂和坝砂,水动力强则形成坝砂,水动力弱则形成滩砂;滩坝砂平行于湖岸线呈带状分布,易于形成岩性圈闭。滩坝砂受砂体发育规模、储层物性、断裂输导体系及封堵性等多种因素控制,在滩坝砂较为发育的东三下段,靠近海南断层、盖州滩断层且封堵条件优越的滩坝砂最易于成藏。     

山东省平阴县阎庄铁矿床地质特征及成因分析

阎庄铁矿位于汶上—东平成矿带北侧，为探讨该矿床成矿标志，通过研究矿床地质特征，分析其成因并总结找矿标志，对区内找矿工作具有借鉴价值。矿体赋存于山草峪组中，其形态受基底背斜控制，呈似层状产出，岩浆岩对矿体的连续性起破坏作用。矿床成因为与新太古代火山活动及区域变质作用有关的沉积变质型铁矿床，泰山岩群变质岩系与磁异常是该类型矿床的找矿标志。

内乡县李沟矽线石矿床地质特征及矿床成因

李沟矽线石矿床位于“豫西南高铝三石成矿带”中,受区域地层、构造及岩浆活动影响显著,属沉积变质矿床。该矿床赋存于古元古界雁岭沟组片岩内,矿床受地层和褶皱构造控制,矿体呈层状产出,成矿地质条件较好。本文在研究前人地质勘查资料的基础上,总结了该矿床的区域及矿区成矿地质条件,并对该地区矽线石矿的矿床成因、找矿标志进行了探讨。笔者认为李沟矽线石矿床及区域地层、构造、岩浆活动构成了“三位一体”的控矿机制,该矿床的周边地区内矽线石矿床(点)分布较多,李沟矽线石矿床及外围地区具有寻找矽线石矿的较好找矿前景。     

薄壁带筋轮座注射成型表面气纹形成机理与缺陷消除

以某薄壁带筋轮座件为研究对象,针对零件表面气纹缺陷,基于Moldflow仿真对熔体流动规律和气纹的形成机理进行分析,利用金相显微镜对熔体结合位置冷却后的微观形貌进行观测,对结合位置的气泡与表面气纹的联系进行了分析,结果表明在熔体结合位置缺少相应排气时,熔体前端的空气难以排出,易产生气纹;基于表面气纹缺陷分析,结合模具和产品具体结构,提出增加排气镶件、修改进胶点和调整局部壁厚等解决方案。结果表明,采用修改进胶点至加强筋处同时增加加强筋壁厚的方案,可使熔体最终结合位置从按钮槽附近转移至分型面附近,型腔内气体可从分型面排气槽处排出,能有效避免熔体结合处的困气缺陷。最终通过试模验证,实现了零件表面气纹缺陷的消除。     

黑龙江黑河孟德河金矿床控矿因素及找矿标志

孟德河金矿床赋存于多宝山—大新屯北东向成矿带的新元古界北宽河组变质地层中,地层平均Au丰度值为0.17×10-6,为区内金矿床的主要矿源层。矿体呈陡倾斜似层状产于北宽河地层内,普遍发育的岩浆岩为金矿床的形成提供了部分物源和热动力,北东向韧性剪带及张性断裂构造为矿液的运移、聚集成矿提供了良好的场所。在分析矿床地质特征的基础上,探讨了控矿因素,归纳总结了找矿标志,并初步探讨了孟德河金矿床的成因。矿体严格受韧性变形带控制,矿体产于韧性变形带的强烈变形部位,矿床成因类型应为韧性剪切带型。
