| 1. | The discovery and origin of the round columnar joints in the basic dyke swarms 岩墙群圆柱状节理的发现和成因机制探讨 |
| 2. | Basic dyke swarms ; round columnar joints ; cool shrink ; viscous shearing 基性岩墙群圆柱状节理冷却收缩黏滞性剪切作用 |
| 3. | As shown in the close - up , these rock layers are characterised by six - sided , columnar joints , from north ninepin island 近看这些岩层有六面,成圆柱状自北果洲连接一起。 |
| 4. | Penghu islands , mainly composed of basalts , enjoy well - developed columnar joints that create many dramatic geological and landscape types of scenery 摘要澎湖群岛主要由玄武岩构成,岛上有各式各样独特的地质、地貌景观。 |
| 5. | The round columnar joints show that the dyke swarms are in upper crust brittle tectonic setting , and the western shandong block is brittle extensional in the mesoproterozoic time 岩墙发育圆柱状节理表明岩墙侵位时地块已经处于上地壳脆性构造环境,中元古代鲁西地区是一个脆性伸展的大地构造环境。 |
| 6. | The round columnar joints are one of the flow structures showing the horozontal emplacement of basic dyke swarms . the round columnar joints show that the basic dyke has rheological behaviour of the viscous shearing in magma emplacement 岩墙发育圆柱状节理表明出露的是岩墙的顶部,反映基性岩墙群侵位时岩浆具有黏滞性剪切作用的流变学特征。 |
| 7. | A rare kind of primary round columnar joints is developed in the basic dyke swarms in the western shandongwhich is made of the radial joints and the round columnar joints with same axis vertical to the strike of the dyke , arranged one by one along the strike of the dyke 在鲁西地区前寒武纪基性岩墙群内发育一种罕见的原生圆柱状节理,由同轴圆柱状节理和放射状节理组成,垂直于岩墙走向,沿岩墙走向排列,是一种指示岩浆水平侵位的流动构造。 |
