| 3. | The geographical and histological division of primate in henan province 河南灵长类动物地史分布初探 |
| 4. | With the geological evolution in precambrian , minerogenetic materials and types of mineral deposits obviously varied and increased 随著中国前寒武纪地史的演化,成矿物质种类和矿床类型具有明显的变化和增多。 |
| 5. | Tectonic - lithogenic - mineralogenetic epoch and its geologic history evolution indicate that intracontinental rifting stage ( t3 ~ e1 ) is the main metallogenic period of the jiangda tectonic belt 构造-成岩-成矿定年与地史演化研究表明,江达构造带主成矿期为陆内裂谷期。 |
| 6. | In the new plan , the position of the studied strata in the stratigraphic column of late precambrian of china shows an impotant relation between sinian system and qingbaikou system on the geologic and biologic evolution 新方案中这些地层在我国晚前寒武纪地层柱中的位置,反应出了震旦系与青白口系的地史演化及生物演化间的重要关系。 |
| 7. | Baoshan is located in the southern part of the ' bee - waist - structure ' of the three - river area and it is relatively stable in it ' s geological history , so it ' s not the emphasis of finding massive sulfide deposits 保山地区位于“三江” “蜂腰”构造南部散开端,因其在地史发展过程中长期处于构造相对稳定的状态,人们并未把该区作为探寻块状硫化物矿床的重点。 |
| 8. | Aad , it is due to the complicated geological structural environment resulted from the separation , merging , collision of plates which consists of land nucleus in geologic history , and it results in the multiple cyclic state of china s land nucleus development 而造成中国油气地质条件的复杂性的地质构造环境,则是在地史中各陆核组成的板块之间分合和碰撞,使得中国陆核的发展呈多旋回状态。 |
