  "Golden triangle" area bordered on Yunnan-Guizhou-Guangxi was one of the most important Carlin-type gold deposits concentration areas.Deep understanding of Carlin-type gold deposits in Guizhou and Guangxi Province had reached through several decades studies, but geological environment was very complex in the southeastern Yunnan, and Carlin-type gold deposits produced in the southeastern Yunnan were different from that of America, few studies were taken there.Based on a large number of field work, studies on the geological characteristics combining with geochemistry characteristics were taken, and analysis the genesis of Laozhaiwan gold deposit.

东亚大陆的基本构造格架形成于中生代,特别是中、晚侏罗世和早白垩世的构造过程,如,强烈的地壳收缩和增厚过程,以及加厚岩石圈垮塌和大规模地壳伸展减薄过程。目前,晚中生代构造的基本特征、阶段划分、阶段转换的时间节点和动力学机制等仍是地质学家普遍关注的科学问题。本文对东亚大陆在侏罗纪晚期-白垩纪早期的沉积作用、构造变形、岩浆作用、变质作用、岩石地球化学和年代学等方面的最新研究成果进行了综述,获得了以下两方

拉萨地体位于西藏高原的南端,其构造演化对青藏高原的形成具有重要的研究意义.虽然目前已有许多研究成果,但是对于印度-亚洲大陆碰撞之前拉萨地体的构造与古地理演化仍然存在很多未知和争论.为了查明拉萨地体早期构造演化过程,我们选取拉萨地体中部的措勤盆地为研究对象.措勤盆地发育完好的中上白垩统地层,其主要包括澎波组和达雄组.研究区位于措勤县城以北约30km,达瓦错附近.澎波组沉积不整合于下伏早白垩世则弄群火
银川断陷盆地位于鄂尔多斯地块西缘,西以贺兰山褶断带与阿拉善地块相邻;东边紧邻鄂尔多斯地块上发育的陶乐-彭阳冲断带;其南缘与青藏高原东北缘的宁南弧形构造带相接.银川盆地新生代以来沉积了巨厚的新生界地层[2-5],使得新生代构造演化成为研究难点.目前关于银川断陷盆地的形成演化特征研究成果较少,丁国瑜和邓起东等[3,8]认为银川盆地受中生代发育的NNE向断裂控制,渐新世受区域水平拉张作用断陷成盆,银川盆

发生于龙门山褶皱冲断带的汶川地震和芦山地震增加了南段山前隐伏断层的库仑应力,而南段具有环青藏高原周缘最陡峭的地形,势必还会存在地震危险性(Liu-Zeng et al.,2009; Zhang,2013; Li etal.,2014).余震重新定位的结果表明汶川地震和芦山地震之间存在75 km 长的地震空区,两次地震之后库仑应力的改变增加了南段地震危险性.针对两次地震中均未发生同震变形的南段山前隐
文章分析了广西金龙铝土矿的物质组成以及嵌布特征,分析可知:(1)金龙铝土矿主要为-水硬铝石型堆积铝土矿,铝硅比较低,属低品位、难选矿石。主要矿物为-水硬铝石,另有大量的铝硅酸盐矿物如叶腊石、高岭石等,及少量赤铁矿、三水铝石等。(2)一水硬铝石具有链状结构基型,属斜方晶系双锥体类。在矿石中嵌布主要呈自形和半自形晶、豆状和豆鲡状、隐晶质和微晶集合体3种形式。在以-水硬铝石为主的碎屑间充填茹土矿物高岭石
