查询词典 geological

After a brief discussion on Earth system science, the author puts forward two viewpoints of the study of metallogeny based on Earth system science, namely:(1) a metallogenic system is a special kind of geological systems;(2) an abrupt geo-event shows dual features both of a disaster and of a mineral resource, i.

Analysis of the sporopollen record and regional geological data indicates that the thick-bedded conglomerate in the upper part of the Kokyar section should be early-middle Pliocene in age,while the deposition of the entire molasse should begin still earlier,i.e.in the late Miocene.

孢粉记录结合区域地质资料分析表明，柯克亚剖面上部厚层砾岩的形成时代应为上新世早中期，而整个磨拉石开始沉积的时代应更早，为中新世晚期。

Meanwhile the SHRIMP zircon U-Pb age of the fine-grained monzonitic granite is (131.4±1.6) Ma. These precise dating results represent the ore-forming period of this molybdenum deposit, the main dominant geological events and suggest its close relationship with buried Yanshan fine-grained monzonitic granite.

文章通过采集WZK1钻孔211.2~214 m细脉浸染状矿石的辉钼矿纯样，获得辉钼矿的等时线年龄为(134.1±3.3) Ma，并对比了矿区细粒二长花岗岩的锆石SHRIMP年龄(131.4±1.6) Ma，两者基本一致，表明矿床的形成主要与隐伏的燕山期细粒二长花岗岩有着密切关系。

This paper reports the zircon SHRIMP U-Pb age data for the Loufanggou metamorphic crystalline rock sheet amphibolite-leptite and biotite-bearing monzonitic quartz schist in the Xianghe area, Shangnan, Shaanxi, in the central part of the Qinling orogenic belt and discusses their geological significance.

其基底组成为广大地质学家所关注。

Because the geological consistency of the earth above the object is Morainal, researches conclude that the Object was buried there more than 10 000 years ago.

由於地球的地质一致性在物体上面是 Morainal，研究员得出结论，物体在一万多年前被埋在那里。

Although different geomorhopologic landscapes appeared unique geological characteristics because of the difference of their formation, the formation of geornorhopologic landscapes are related to the Geologic-tectonic evolutional history and the multicycle magmatic activities, especially the neotectonic movements.

尽管不同类型的地质地貌景观由于成因上的差异而显现出独特的地学特征，但地质地貌景观的形成均与新疆复杂的地质构造演化史和多旋回的岩浆活动、尤其是新构造运动密切相关。

The differences in reservoiring conditions of natural gas and oil, as well as the multicycle developments and evolution histories of major gas bearing basins in China, and the geological environments characterized by relatively active tectonic movements in later period have resulted in the forming conditions of gas fields in China to be more complicated than those in many basins all over the world.

由于天然气与石油在成藏条件上的差异和中国主要含气盆地多旋回的发展演化历史、晚近时期构造运动比较活跃的地质环境，中国气田形成条件较世界上许多盆地复杂和成藏类型较多。总结中国大中型气田的成藏历程，可以新近纪、古近纪和中生代为界将气田的形成归为 4类：1超晚期生烃成藏型；2晚期生烃成藏型；3早期生烃聚集和晚期定型成藏型；4早期生烃成藏型。在这 4类中，以晚期和超晚期成藏和定型为主且分布最广、天然气前景最好、是中国天然气最主要富集领域。早期生烃成藏型在保存良好的盆地也有较好的前景。

By assuming a common mutation rate of the cpDNA-IGS regions, our inferred timings of these events (0.82-4.39 Mya) broadly agrees with both previous geological and molecular estimated time of drainage rearrangements in this region.

基于叶绿体核苷酸平均替代速率，我们推测出了不同分支间的隔离时间大约在0.82-4.39Mya之间，结果与已有的鱼类分子系统的研究结果基本一致，也与现有的地质学文献关于红河改道的时间一致。
