武夷山脉中段晚太古代宇宙尘特征

武夷山脉中段晚太古代宇宙尘赋存于上太古界天井坪组。粒度一般为0．15-0.2mm，最大0.32mm，最小0.042mm,形态呈单球体、不规则形或碎片状，以前者为主。在扫描电镜下表面具烧蚀、蜂巢状气印、气孔状、刺(瘤)突趁、晶洞及偏心双层等结构。宇宙尘由内核和熔壳组成；内核是自然铁(a-Fe)，含Fe、Cr、Ni、Co等元素；熔壳是磁铁矿或方铁矿，除Fe外尚含Si、Al、Cr、Mn、S等元素：根据其结构、构造组成和物质成分的综合分析结果，并与国内文献资料进行对比，本区宇宙尘可能是铁陨石在大气中的消融物或在太空中的碎裂物。     

Experimental Research on Microscopic Indicators of Temperature＇ s Returning-to-Zero in Deformation of Calcite and Discussions of Correlation Problem

In order to determine the degree of returning-to-zero of temperatures of deformed calcite, a series of rock-breaking experiments were designed to test calcite-rich limestone samples under fixed confining pressures and different temperatures. The consolidated deformed samples in their initial state were observed under a microscope and the microscopic indicators in different zero-returning states were put forward, thus providing a microscopic foundation for evaluation of reliability of dating values of deformation in calcite. At last, the correction of dating values of deformation for samples whose temperature has not yet returned to zero is discussed.     

周家塆岩体锆石年龄值及其地质意义

大别山麓前寒武纪变质岩分布区，具片麻状构造的花岗岩类分布较广。周家塆岩体即为一例。前人主要依据片麻理发育程度，以类比的声法，将这些片麻状花岗岩时代定为“大别-吕梁期”或“晋宁期”，而将周家塆岩体定为燕山早期花岗岩侵入体。这些结论，均缺乏同位素年龄数据佐证，有的也不切合地质实际，因而谬误不少。     

山东招远金矿矿石中首次发现宇宙尘埃—镍纹石

招远金矿田的人工重砂样品中首次发现宇宙尘埃——镍纹石.文中介绍了镍纹石的形态特征、物理性质和x射线粉晶与红外光谱分析结果.在此基础上,作者进一步认定招远金矿是在地层经过混合岩化和花岗岩化作用保留下来的产物.     

Medical geology：new relevance in the earth sciences

The interdisciplinary fieldresponds to the need to betterof “Medical Geology“ understand the relationships between human health and our surrounding environment. The influence of earth resources, natural environmental factors and land-use on human health has long been recognized, dating back to ancient Rome and Peru‘s Inca civilization. Today links between the natural environment and health can be found throughout the world. This review introduces the historical context of this particular type of research, contrasts the direct geological and indirect natural hazard influences on healthas a framework of study, elaborates on pathways of elemental accumulation in the body and provides examples of specific geochemical behaviours and diseases that are often associated with either too much or not enough of certain elements which comprise the Earth.

青岛文昌鱼的生活史──年龄、生长和死亡研究

于１９８９年８月－１９９０年７月对青岛文昌鱼的生活史进行研究。结果表明：（１）青岛文昌鱼种群由４个齿组组成，它至少生产４ａ以上，甚至可达６ａ左右。（２）在Ⅰ、Ⅱ齿时生长较快，平均年生长１３－１５ｍｍ，Ⅲ龄后生长速度减慢，即使同一年龄组的文晶鱼，在不同季节其生长速度也不同。（３）在冬春采集的文昌鱼中Ⅲ龄组的峰值较小。（４）繁殖季节过后，老龄文昌鱼因衰老而死亡。
