关山动物群近些年来发现了大量特异埋藏动物化石,等刺虫是其中最常见的化石之一.过去曾经报道过云南昆明高楼房剖面的I.minor(小型等刺虫)和武定石将军的I.wudingensis(武定等刺虫),但两者的形态描述都存在明显问题.报道了采自云南省昆明市官渡区高楼房剖面寒武系黔东统乌龙箐组的大量等刺虫化石,共计3个种:I.minor,I.wudingensis和I.guanduensis sp.nov.

关山动物群近些年来发现了大量特异埋藏动物化石,等刺虫是其中最常见的化石之一.过去曾经报道过云南昆明高楼房剖面的I.minor(小型等刺虫)和武定石将军的I.wudingensis(武定等刺虫),但两者的形态描述都存在明显问题.报道了采自云南省昆明市官渡区高楼房剖面寒武系黔东统乌龙箐组的大量等刺虫化石,共计3个种:I.minor,I.wudingensis和I.guanduensis sp.nov.(官渡等刺虫),其中以小型等刺虫占统治地位.对小型等刺虫的形态特征进行修正,特别是确定了其后基刺构造;对

利用塔克拉玛干沙漠腹地近地层湍流观测资料,计算并分析了不同稳定层结条件的湍流速度谱、温度谱及局地各向同性特征。结果表明,湍流速度谱和温度谱在惯性副区均满足Kolmogorov的-2/3指数规律,且稳定条件的相关系数更高;速度谱满足湍流各向同性的低频限制理论。近中性条件的温度谱和弱不稳定条件的速度谱在高频段有尾部上翘现象;稳定情况下的v谱和近中性条件的u谱、T谱在低频处也有上翘现象。沙漠腹地水平湍流
利用加密自动站、卫星云图及雷达图像等资料,对2010年6月7日白天到夜间宁夏中北部地区出现的短时暴雨天气成因及中尺度系统演变进行分析。结果表明,此次短时暴雨是在"东高西低"稳定的环流形势和锋面过境背景下,500hPa西风槽,700hPa切变线、低涡、低空急流,850hPa切变线,地面冷锋等主要影响系统相互配合、共同作用下发生的;大降水落区位于低空急流左侧与切变线尾部的辐合区,这可作为宁夏中尺度暴雨

孤立浅水碳酸盐台地是黔桂地区晚古生代古地理格局中的重要组成部分,拉张伸展的区域构造背景和台缘同沉积断裂的差异升降对其发展演化的控制作用一直是关注的焦点.来宾铁桥剖面位于来宾-合山孤立碳酸盐台地东南边缘,本文以该剖面茅口组为重点,研究台地-盆地转变过程中该台地边缘的沉积特征和相带构成,探讨该孤立台地边缘沉积演化的主要控制因素.宏观和微相沉积特征表明,茅口期下部地层(第1旋回)为典型的开阔台地相沉积;
