横山中侏罗世延安期响水曲流河道砂体的储集性研究

响水砂体是一出露比较完整的中生代的曲流河河道沉积。通过大断面写实的研究方法，运用沉积体系分析、层序地层分析、砂体内部沉积构成分析等方法，比较细致地划分了砂体内部成因单元和储层岩性相，从成因上研究了影响油气运移的沉积因素。通过砂体断面上一定间距的比较均匀的采样，并根据测试成果编图，展示了各种孔沙参数在空间的变化特点及其与各种界面、沉积水动力能量的联系，并依此总结曲流河点坝渗透率的分布模式。     

秦岭浸染状金矿床与热水沉积铅－锌矿床地质地球化学共生富集关系──值得重视的成矿系列和找矿方向

秦岭沉积岩区浸染状金矿床与热水沉积铅锌矿床共生富集关系是独特的．金主要以伴生金、共生金及独立金矿床形成产出。分别对三种形式的金矿化与铅锌矿床的空间分布关系、成因联系进行了评述，从地质地球化学方面进行了对比，对它们共生富集规律进行了探讨。目的在于拓宽秦岭沉积岩区找矿思路，争取在找矿认识上有所突破。     

滇西孟连曼信一带火山岩微枕状构造特征及其地质意义——兼论曼信—老厂一带火山岩时代

首次发现报道了曼信一带海相火山岩微枕状构造的地质特征。主要根据野外第一手资料，分析探讨了曼信—老厂一带火山岩的时代，主要认识是：“依柳组”火山岩的主要形成于晚二叠世；老厂地区泥盆纪—中晚石炭世有少量基性—中性火山活动及三叠纪火山活动。     

论界牌峪地区“陀状”角砾岩成因及找矿意义

湖南石门界牌峪地区存在大量的所谓“陀状”角砾岩，它们互不相连，外观圆形，有的聚集成群或者呈完全孤立的山包。角砾岩地表多为椭圆状和等轴状，与围岩多呈刺穿状接触。通过地质学、岩石学和地球化学等方面研究，认为该区“陀状”角砾岩是一种由热泉气体及部分物质在封闭还原条件下产生急剧爆发所形成的特殊的角砾岩群。它们是一种极好的容矿控矿体，具有重要的找矿意义     

The Confirmation of a New Type of Chondrites and Their Cosmochemical Significance

The data available show that some Antarctic carbonaceous chondrites are similar to Cl meteorites.Tehy contain a lot of phyllosilicate aggregates and the oxygen isotopic composition of the whole-rock samples is approximate to that of C1 chondrites,so they are named after quasi-C1(Q-C1)chondrites Unlike Cl metcorites,the Q-Cl chondites possess chondrule structrue,and the compositions of hih temperature condensates(chondrule fragments,mineral grains or aggregates)show that the oxygen fugacity varied within a wide range in the surroundings where they were formed,similar to the variation range from E.H.L,LL to C group chondrites.It is inferred that the Q-C1 chondrites could be formed at the edges far from the equator in the whole asteroid region of the solar nebular disk.where the nebula was lower in density and the condensates were lower in accretion velocity,so that the hydration of chon drules and matrix occurred during the late stage of nebular condensation.The discovery of the Q-Cl chondrites and the fact that the earth and other terrestrial planets contain water indicate that at the edges far from the equator in the terrestrial reigion of the solar nebular disk,a large amount of water was incorporated into the lattice of minerals in the condensates as a result of hydration during nebular condensation,and then found its way into the interior parts of the Earth and other terrestrial planets due to accretion.
