The authors analyzed background of geotectonics for basalt containing Pt and Pd in the studied area. On the basis of the type of mineral deposit containing PGE, the authors also studied occurrence of Pt and Pd.

在分析黔西玄武岩中Pt、Pd岩石载体所处的大地构造背景、含铂矿床的可能类型和岩石化学特征与Pt、Pd可能存在状态的关系的基础上，研究了黔西玄武岩中R、Pd存在状态。

The intention is to drill a 250m deep stratigraphic exploration bore which will allow Widespread to confirm the shape of the Kotuku anticline, recover samples of the rock strata and the nature of any fluids contained within it.

此举的目的是钻一个250米的深层勘探孔，便于该公司确认Kotuku地区的背斜形状，采集一些岩石层组织样本及岩石层中天然液体的样本。

We analyzed the tectonic differences and deep geodynamic characteristics based on the tomographic results, which show high velocity anomalies at the uppermost mantle beneath the northeast SCS, and depict the lithospheric mantle extension from South China continent to marginal sea. Because of the low temperature and thick lithosphere beneath the northeast SCS, it seems no magma intruded from mantle, so we inferred that the rift may only occur in the crust rather than extend to the upper mantle, which shows the nature of nonvolcanic continental margin.

结果表明：南海东北部表现出陆架地区的岩石层特性，属于华南大陆向海区的延伸，岩石层厚度较大，现今不存在大规模的地幔热流活动，推测大陆边缘张裂作用仅限于地壳内部而没有延伸进入上地幔，具有非火山型大陆边缘的深部特点。

In the course of program designing, OLE mechanism and Graph for Windows have been used to generate specific geological triangular chart from computer instead of manual work in before. By using PowerBuilder 7, inquiry through a clue of combination of conditions including structural tree, strati graphic tree, well number tree and sample number tree is realized, which meets the thinking way of geologists.

在程序设计方面，针对岩石名称分类复杂、量化定名烦琐的现状，采用OLE机制和Graph for windows图形工具，对岩石含量数据进行相对数值转换，完成了平面上呈三角形排列的三个直角坐标系统的叠加，避免了人工绘制地质三角图随意性大、精确度低的问题，极大地提高了工作效率。

The rock mass rating, rock mass classification and support systems proposed for fault zones in Tuzla tunnel are insufficient for explaining the deformation and failure mechanisms encountered in the tunnel.

岩石强度等级，岩石类别，支护结构等关于Tuzla隧道的断层带的资料不足以解释隧道的变形，也没有找到一台合适的机械。

Rocks in these regions, known as Imdr Regio, Dione Regio and Themis Regio, were anomalously bright compared with their surroundings, suggesting that they were relatively young and unweathered by the corrosive Venusian environment.

这三个区域分别被称为&Imdr Regio&，&Dione Regio&和&Themis Regio&，这些区域的岩石相对于它们周围的岩石来说，亮度高的出奇，表明它们相当年轻，还没有被金星的腐蚀性环境所风化。

Combinds with several calculating ways of forming ages of rocks (Pb-Pb isochron way, inconsistent line model calculating way and three-stage model calculating way), a way to calculate element content of samples and forming ages of rocks was summarized.

本文主要是研究该法的计算，分析样品中元素量的计算，并结合几种岩石年龄方法（Pb-Pb等时线法、不一致线模式计算法、三阶段模式计算等）的计算，归纳总结出计算样品中元素量和岩石形成年龄的方法。

Secondly, study on bleaching of sandstone based on field characteristics, petrography, geochemistry and compared with other sandstone related, combined with geological setting of gas seepage in the area, reveals that natural gas leakage is responsible for bleaching of the sandstone on top of Yan\'an formation. The bleaching resulted from interaction between the reductive fluid and the rock. At the same time the bleaching suggests that the northeast of basin has experienced large scale gas seepage.

在此基础上，通过漂白砂岩野外露头地质特征、岩石学、地球化学以及相关砂岩的对比研究，结合研究区天然气逸散的地质背景，揭示砂岩漂白现象为上古生界天然气逸散过程中，还原性流体与岩石作用的结果，同时也表明其指示了天然气的大规模逸散作用。

Anticlines are folds that arch upward, with older rocks in the center and younger rocks on the outside.

背斜是褶皱的向上的拱门，和更老的岩石在中心和较年轻的岩石在外侧。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
