Harmonic Analysis of Sedimentary Cyclic Sequences in Kansas, Midcontinent, USA

Several stratigraphic sequences in the Upper Carboniferous (Pennsylvanian) in Kansas (Midcontinent, USA) were analyzed quantitatively for periodic repetitions. The sequences were coded by lithologic type into strings of datasets. The strings then were analyzed by an adaptation of a one-dimensional Fourier transform analysis and examined for evidence of periodicity. The method was tested using different states in coding to determine the robustness of the method and data. The most persistent response is in multiples of 8–10 ft (2.5–3.0 m) and probably is dependent on the depositional thickness of the original lithologic units. Other cyclicities occurred in multiples of the basic frequency of 8–10 with persistent ones at 22 and 30 feet (6.5–9.0 m) and large ones at 80 and 160 feet (25–50 m). These levels of thickness relate well to the basic cyclothem and megacyclothem as measured on outcrop. We propose that this approach is a suitable one for analyzing cyclic events in the stratigraphic record.     

Organism relics or kerogens in oils as oil-source rock correlation indicator

Organism relics or kerogens in oils are first obsenred by a confocal laser scanning microscope (CLSM) and a transmission electron microscope (TEM). The complexes of kerogens in oils are characterized by the presence of a great variety of microfossils or macerals. These kerogens in oils are mainly the residues of the original organic substances from which oil formed, and minor kerogens from enclosing rocks enter the oils, therefore, the components and types of the kerogens in crude oils can serve as an indirect indicator of oil-source rock correlation. This method was applied to Jurassic oils in the Junggar Basin and the Turpan-Hami Basin, and there are two types of the kerogens in oils: one containing a lot of macerals from terrestrial plants may derive from coals, and the other, characterized by a high content of microscopic algae, fungus spores and Acritarch, may originate from Permian organic matter. In addition, the reflectance of the vitrodetrinites in oils can be used as an indicator of oil-source rock correlation.     

新疆西准噶尔金矿成矿域矿床成因及矿床模式

新疆西准噶尔金矿成矿域是大区域内成矿单位，成矿域中所有金矿床（点）均产于地壳构造活动带。富含金的地幔物质沿深大断裂上升侵位，分熔，产生岩浆，火山活动，壳下重熔再熔、火山物质沉积变质作用，在漫长的华力西期经历反复多次的构造变动，形成超基性－基性火山－沉积－变质含金建造，是准噶尔－哈萨克斯坦古板块碰撞作用的产物。     

蚀变岩中物质迁移的定量计算：以锡矿山锑矿床为例

本文提出了确定沉积岩蚀变作用过程中的不活动组分的方法，并以锡矿山锑矿床为例，定量计算了蚀变岩中各组分的带入带出量，研究表明：锡矿山锑矿硅化过程中ＴｉＯ２和Ａｌ２Ｏ３为不活动组；ＳｉＯ２，Ｋ２Ｏ，Ｎａ２Ｏ及锑，硫，坤，汞，铅和钡为带入组分；而ＣａＯ，ＭｇＯ，Ｆｅ２Ｏ３，ＭｎＯ及铜，锌为带出组分，锑，钡，硫，ＳｉＯ２和ＣａＯ有较大的带进或带出量，锡矿山锑矿床矿石矿物为单一辉锑矿可能是由于矿液中缺少其它

益阳市矿泉水的基本特征及形成机理探讨

益阳市矿泉水是一种弱酸、弱碱性、低矿化、富含偏硅酸的ＨＣＯ３－Ｃａ天然优质饮料矿泉水。它赋存于武陵期海底裂隙式喷溢形成的基性火山岩－细碧玄武岩的构造断裂和半风化层的风化裂隙之中。矿泉水水量起源于多途，化学成分形成于多因，是多因复成的产物。     

四川盆地碳酸盐岩油气勘探实践与认识

四川盆地烃源十分丰富。但油气演化程度高,大多已进入高成熟和过成熟阶段,至今只在侏罗系发现有油藏,三叠系及其更老地层皆为气藏。储层主要为碳酸盐岩,其特点是低孔低渗,平均孔隙度仅1.7%,平均渗透率小于1×10~(-3)μm~2,但其中的“孔洞发育层段”平均孔隙度可达3%～6%。根据四十年的勘探经验,加强预探并争取新发现是四川盆地油气勘探发展的关键。预探中,按构造带规划大中型气田勘探目标,将成藏条件相似、地域上相邻的局部圈闭群作为一个整体勘探对象,实行稀井广探,少井高效。“八五”以来,在高陡构造带勘探技术、储层横向预探技术等方面有长足的进步,勘探成效不断提高,实现了资源序列的良性循环。     

2003年6、7月西昌二次4.8级地震的预测与分析

2003年6月17日和7月10日,先后在四川省西昌市和西昌-昭觉间发生2次ML4 8级强有感地震.对于这2次地震,我们曾作了较好的中期和短期预测.但是对于6月17日发生的第一次ML4 8级地震,未能做出临震预测;对于第二次地震,则在7月1日向上级填报的周会商表中作了明确的临震预测,7月10日,在西昌-昭觉间发生了ML4.8级地震.根据西昌地震遥测台网各子台的P波初动求解震源机制,结合地震所处的地质构造以及现场烈度考察圈定出的结果分析,认为这二次地震是由安宁河断裂带、则木河断裂、凉山断裂所围成的凉山小菱形块体活动的结果.
