    • 摘要: 滇东北会泽地区广泛出露震旦纪-寒武纪过渡地层,主体为一套浅海相碳酸岩夹碎屑岩.近期开展的1∶5万区域地质矿产调查,首次在会泽地区五星乡一带灯影组上部发现凝灰岩(斑脱岩)夹层,并进行了SHRIMP锆石U-Pb测年,获得其206pb/238U年龄加权平均值为538±5 Ma,其表明灯影组上段上部的沉积时代为早寒武世梅树村期.此外,通过与邻区前寒武系-寒武系界线对比研究,会泽地区震旦系与寒武系界线应置于该凝灰岩(斑脱岩)底界,即灯影组上段非正式地层单位(中谊村段)底部.

    • 摘要: 贵州铝土矿露头及浅覆盖区勘查工作已近乎完成,目前铝土矿多为隐伏矿,本次黔中水田坝地区铝土矿勘查主要寻找中深部隐伏矿体.黔中水田坝地区铝土矿位于黔中铝土矿之南东,赋矿层位为石炭系九架炉组(C1jj),其底板为寒武系娄山关组地层(∈2-3ls),二者为假整合接触.铝土矿的品位、厚度严格受到不整合面上岩溶洼地、岩溶漏斗的影响,平面上变化较大.根据矿区含铝岩系与顶底板的物性差异,本次在黔中水田坝地区铝土矿的勘查中,选用音频大的电磁测深法(AMT)进行勘查,划分含铝岩系与顶底板的界线及含铝岩系厚度,结合地质测量及探矿工程资料综合分析,圈出含矿有利部位,进而钻探验证,取得了较好的效果.

    • 摘要: 中—晚三叠世之交是四川盆地海陆转换的关键时期,区内中三叠统雷口坡组和上三叠统须家河组是研究该时期古生物多样性变化与古气候环境演化的重要地层单元.四川宣汉七里峡剖面出露完整连续且层序清晰的中三叠世与晚三叠世海陆过渡相地层,是进行四川盆地中—晚三叠世海陆转换研究的理想剖面.基于沉积学理论与研究方法,根据七里峡剖面的沉积岩类型、颜色、构造并结合包裹体、有机碳同位素以及古生物和聚煤特征,将宣汉七里峡地区中三叠统雷口坡组与上三叠统须家河组界线地层沉积相划分为蒸发台地—潟湖潮坪—滨岸沼泽—河口砂坝等类型,揭示了一个完整的海侵—海退旋回.结合古植物和孢粉等化石资料,对宣汉地区晚三叠世初期的古气候特征进行简要分析.

    • 摘要: 贵州铝土矿资源储量丰厚,分布面广,但多为隐伏型沉积型矿,仅有的易辨别、易发现的地表或浅层铝土矿已经开发殆尽,在此开展隐伏铝土矿的物探方法试验研究对今后勘查工作具有重要的指导意义。本文简要介绍了AMT基本工作方法以及贵州金沙长沟工区的地质和地球物理特征,重点讨论了AMT在长沟工区铝土矿勘查中的应用效果,通过对电阻率断面图的综合推断解释,划分出了二叠系、石炭系、寒武系之间地层界面,圈出了含矿有利部位。经钻孔验证,取得了较好的找矿效果。%Guizhou has rich and extensively distributed bauxite resources, but bauxite deposits there are mostly concealed sedimentary ones. The easily⁃discovered shallow and surface bauxite deposits have almost been totally exploited, and hence the experimental test of geophysical methods in search for concealed bauxite deposits is of great significance for further ore⁃prospecting work. In this paper, the authors describe in brief the basic working procedure of the AMT method as well as geological and geophysical characteristics of the Changgou work area in Jinsha district, Guizhou Province, and emphatically discuss the application results of AMT in the bauxite explo⁃ration of Changgou work area. Based on integrated inference and interpretation of the resistivity section, the authors recognized the stra⁃tigraphic boundaries between Permian, Carboniferous and Cambrian, delineated favorable ore⁃bearing places, and attained fairly good ore⁃prospecting results, as demonstrated by later drilling verification.

    • 摘要: 以西藏纳屋错地区1∶5万区域地质调查为例,阐述了在地质调查中综合运用RS、GIS和GPS技术划分地层界线的几种方法.对于地层界线不同类别的野外出露形态,采取差别取舍的办法合理运用3S技术协助划分界线.研究表明,当野外实地界定地层界线遇到困难时可借助遥感影像先行识别,当遥感影像精度欠佳时则由实地勘察确定界线,情况复杂时还常常同时运用3个“S”技术和其他相关地质研究成果综合厘定地层界线.%Taking the 1 : 50 000 regional geological surveying in Nawucuo area, Tibet, this paper discusses the integrated application of RS, GIS, and GPS technologies in determining the stratigraphic boundary in field geological surveying work, believing that when it is difficult to ascertain the stratigraphic boundary in fieldwork because of different appearances in stratigraphic boundary, RS image can be used to help. In some difficult situations three "S" technologies and other geology information may simultaneously be used to fix the stratigraphic boundary.

    • 摘要: Based on the theories of sedimentology and reservoir geology, taking Guan 1+2 sand member in the south block of Gudao Oilfield as an example, using the logging data in the condition of dense well patterns sufficiently, the type,characteristic,distribution and application of the markers for stratigraphic correlation and subdivision were studied.Firstly, the macro feature of the Guan 1+2 sand member included logging response, seismic section, etc.;secondly, the marker for stratigraphic correlation and subdivision was confirmed according to the response characteristics of induction conductivity and natural potential curves; thirdly, the confirmed markers were used to obtained the structural contour map of the top boundary of the Guan 1+2 sand member in the south block of Gudao Oilfield.The results showed that the regional marker was lack, but the local markers developed; the local markers included mudstone, sandstone, carbonate, and sand-mudstone combination; the characteristic of mudstone marker was high induction conductivity, sandstone marker was low resistivity and “box-shape” or small “bell-shape”spontaneous potential, carbonate marker was high resistivity and microresistivity, low interval transit time and spontaneous potential, sand-mudstone combination marker was strong comparability of the induction logging curves;the distributed areas of mudstone and sandstone were large, usually connected body; the distributed areas of carbonate and sand-mudstone combination markers were small, usually striped body; the composite distribution of the above four kinds of markers were all around the studied area.In general, the local markers could be used for the stratigraphic correlation and subdivision in similar area completely if the regional marker was lack.%基于沉积学和储层地质学理论,以孤岛油田南区馆1+2砂层组高弯曲流河沉积为例,充分利用密井网条件下的测井资料,研究储层细分对比中的标志类型、特征、分布及其应用.首先,介绍了馆1+2砂层组的测井响应、地震反射等宏观特征;接着,利用感应电导率曲线、自然电位曲线的响应特征寻找细分对比标志;然后,将选取的标志联合使用得到孤岛油田南区馆1+2砂层组的顶面构造图.结果表明:研究区缺少全区性标志,但存在局部性标志;局部性标志有泥岩类、砂岩类、"钙质尖"类、砂泥组合类等4类;泥岩类标志表现出高感应电导率特点,砂岩类标志表现为低电阻率,自然电位曲线呈"箱形"或小型的"钟形","钙质尖"类标志表现为高电阻、高微电阻、低声波时差,低自然电位值的尖锋,砂泥组合类标志表现为感应曲线特征的可对比性强;泥岩类和砂岩类标志分布面积较大,呈局部连片状;"钙质尖"类和砂泥组合类标志分布面积较小,呈条带状;上述4类标志在平面上的叠合分布完全覆盖研究区.总之,充分利用好局部性标志,同样能够很好地进行类似地区的储层细分对比.
