Paleogene basalts from the liaohe basin, northeastern china, are dominated by alkaline olivine basalts and olivine basalts. These basalts are generally enriched in high field strength elements (HFSE), depleted in large ion lithophile elements (LILE) and comparable to those of typical ocean island basalts (OIB). Positive anomalies of Ba, Sr and Zr with high Nb/U, U/Pb, Ce/Pb and Zr/Hf ratios imply that materials from an oceanic crust had been added to the mantle sources of the basalts. In addition, the basalts are generally depleted in Sr, Nd and Pb isotopes, indicating that an enriched mantle (EMI) and a depleted mantle (DM) sources were added to the OIB-like resource. Comprehensive {2. on lithosphere evolution and tectonic setting of the liaohe basin and surrounding areas suggests that these basalts were derived by variable degrees of partial melt-ing from an upwelling asthenosphere mantle. Materials from an oceanic lithosphere were added to the source in company with Paleogene tectonic transition from platemargin to intraplate envi-ronment. Retreating and steepening of the subducting Pacific oceanic plate could be the main cause for the tectonic environment transition.

Independent of Indochina extrusion, the South china Sea experienced a process from passive continental rifting to marginal sea drifting. According to the fault patterns in the Beibu Gulf basin and the Pearl River Mouth basin, the continental rifting and early spreading stage from 32.to 2. Ma were controlled by extensional stress field, which shifted clockwise from southeastward to south southeastward. From 2. Ma on, the sea spread in NW-SE direction and ceased spreading at around 15.5 Ma. Integrated geological information with the assumption that the South china Sea developed along a pre-Cenozoic weakness zone, we did analogue experiments on the South china Sea evolu- tion. Experiments revealed that the pre-existing weakness zone goes roughly along the uplift zone between the present Zhu-1 and Zhu-2.depression. The pre-existing weakness zone is composed of three segments trending NNE, roughly EW and NEE, respectively. The early opening of the South china Sea is accompanied with roughly 15° clockwise rotation, while the SE sub-sea basin opened with SE extension. Tinjar fault was the western boundary of the Nansha block (Dangerous Ground), while Lupar fault was the eastern boundary of the Indochina, NW-trending rift belt known as Zengmu basin developed between above two faults due to block divergent of Indochina from Nansha. In the experiment, transtensional flower structures along NW-trending faults are seen, and slight inversion occurs along some NE-dipping faults. The existence of rigid massifs changed the orientations of some faults and rift belt, and also led to deformation concentrate around the massifs. The rifting and drifting of the South china Sea might be caused by slab pull from the proto South china Sea subducting toward Borneo and/or mantle flow caused by India-Asia collision.

关键词： South china Sea, rifting and drifting, clockwise rotation, analogue modeling, rigid massifs.

限定了井眼方向的待钻井眼轨道设计问题需要求解一个7元非线性方程组,通常使用的数值迭代方法有许多固有的缺点,提出了一个新方法──代数法:将原始非线性方程组化简成一个三元多项式方程组,再进一步归结为求一个10次多项式方程全部正实数解问题和一个二元线性代数方程组问题。给出了代数法的计算机实现方法,具有计算速度快、数值稳定性好、存储需求小等特点。代数法具有与解析法相近的良好数学性质,能够对问题是否有解做出事前判断;在问题存在多个解的情况下,能够正确求出全部的解。所使用的数学化简技巧能够推广应用到求解定向井、水平井的井眼轨道设计问题中,有重要的理论价值和应用前景。

对地层层序、地震相、沉积相、地化分析实验数据以及热演化程度进行了研究,提出了一种定量评价泥质烃源岩的有效方法。在层序地层格架下,以重构声波时差曲线为约束,反演出各沉积相带下的烃源岩分布;采用盆地模拟技术,外推出无实测镜质体反射率(Ro)值井区的Ro数据,经由中子、深侧向电阻率和密度测井曲线获得的成熟度指数的校正后,得出各井的Ro数据,再通过克里金插值生成Ro数据体。烃源岩分布与Ro数据体二者结合即可预测出优质烃源岩的分布。该方法的优点主要表现在将储层预测的随机相控反演运用到有利烃源岩分布的预测中,并将Ro数据由点上升到体,实现了湖相泥质烃源岩的静态定量评价。利用该方法对辽河坳陷西部凹陷清水洼陷的泥质烃源岩进行了评价,取得了较好效果。
