松辽盆地白垩纪古气候特征及其变化机制

本文综合研究了松辽盆地白垩纪古气候的沉积记录、孢份古植物群记录及碳、氧同位素地球化学特征，得出了松辽盆地白垩纪古气候的演变规律。并认为碳族国与古气候旋回有密切的对应关系，大气中ＣＯ＿２含量的变化是古气候变化的根本原因。每一温暖时期的开始都与大气中ＣＯ＿２含量的增加有关，随着固碳作用的增强，温室效应削弱。碳旋回是古气候变化的重要机制。     

Upper Holocene sea-level changes: Paleogeographic evolution and its impact on coastal archaeological sites and monuments

The paper presents the evolution of the geographic environment imposed by sea-level changes in selected sites of the Aegean Sea region during the Upper Holocene. The changes are due, mainly, to paroxysmic phases of the actual neotectonic evolution and to differential—in time and space—block movements, and emerged or submerged coasts. The reconstitution of these coasts is presented and, in some cases, natural harbor morphology is revealed. The use and evolution of these sites is discussed. Other sites concern coastal or inland ancient settlements or constructions affected by submersion by the sea, by the rise of the groundwater table, or by uplift movements. A general discussion on engineering measures to be applied for protection of the antiquities affected by these geographic changes closes the presentation.     

Cyclic sedimentation and climatically caused sea-level changes in the Late Palaeozoic of Central Europe

Significant short-term fluctuations are characteristic of geological history since Precambrian times. Only the younger Quaternary climatic fluctuations are known in more detail as a result of a high grade time resolution. Climatic change can also be postulated with respect to older, cold periods during which polar inland ice sheets developed. From a discussion of endogene and exogene interpretations it is shown that global climatic changes, and the sea-level changes induced by them, as well as changes in the position and extent of climatic zones throughout the world provide a control mechanism for sedimentation which is consistent with cyclic sedimentation in Late Palaeozoic times, and also if the basin subsides non-cyclically. The model allows an explanation of the development of the Permo-Carboniferous sedimentary cycles without numerous short-term vertical oscillations of the earth's crust. In reality, exogene and endogene controls on sedimentation act together in great variety of combinations.     

黔桂泥盆纪层序地层及海平面变化的频幅、速度和相位

通过对广西六景、贵州独山和乌当泥盆系剖面层序、体系域、副层序及作用相和环境相的系统研究,识别出2种层序界面;3种海进过程和10种层序、体系域和相对海面变化.并发现,阶跃型高幅海平面变化形成的层序界面、层序、体系域、副层序和旋回层往往可在大区域追踪对比;剖面作用相、环境相分析是露头层序地层和相对海平面变化研究的基础,剖面上层序、体系域及其反映的相对海平面变化的频率、幅度、速度和相位研究对层序界面、层序、体系域、副层序和旋回层的空间延拓、等时追踪对比和驱动机制的成因解释有重要的指导、预测作用.

大同镇川堡井水位阶变与地震关系初析

统计了大同镇川堡井１９８８年６月～１９９１年１２月原始记录曲线的水位阶变资料，认为该井水位阶变可能反映了口泉断裂的蠕动，也反映了两次大同—阳高地震前应力应变作用的过程。     

内陆表海聚煤盆地的曾想到处分析

在华北石炭二叠纪内陆表海聚煤盆地，海侵的突发性和事件性，泥炭沼泽化的广泛性和等时性，是划分其层序内部构成单元的良好界面。研究表明，华北石炭二叠纪内陆表海聚煤盆地的层序结构为“二元结构型”，即“海侵－高位”，缺少低位体系域。海侵体系域由１～２个小层序构成，而高位体系域由小层序构成。体系域恰与小层序组对应，海侵小层序组表现为弱退积－加积型，而高位体系域则表现为弱进积－加积型。小层序为高精度的岩相古地理编图单位，它为解析层序格架和煤聚积规律提供了最可靠的依据。     

1986年和1987年秋季西太平洋赤道附近海域的辐射状况

本文利用1986和1987年秋季在西太平洋赤道海域取得的短期辐射资料,分析了这一特定海域的辐射状况。揭示了所在海域太阳辐射的一些特征。这对了解该海域海气界面上的热状况以及它对所在海域天气气候的影响无疑都有帮助。     

An aerosol climatology of Samoa

An atmospheric monitoring station is operated at Cape Matatula, American Samoa, by the Geophysical Monitoring for Climatic Change program under the National Oceanic and Atmospheric Administration. A nearly continuous record of condensation nucleus (CN) concentration and multiwavelength aerosol scattering extinction coefficient (_sp) is available from mid-1977 to the present. This report presents the 1977–1983 data. The long-term mean of CN concentration is 274 cm^-3 the long-term mean of _sp (550 nm) is 1.54×10^-5, and no significant long-term, annual, or diurnal trend is apparent in either data record.
