区域对比 meaning in Chinese
regional correlation
Examples
- Regional diversities of soil fertility along the yangtze river in jiangsu province
江苏沿江地区土壤肥力空间分布及其区域对比研究 - Though the regional correlation and study of reservoirs and sedimentary facies , they find the horizontal distribution characteristics of the major reservoir in the research area
储层沉积相区域对比研究表明，主要储层横向展布特征是：灯影组白云岩在研究区广泛且稳定分布，石牛栏组颗粒灰岩主要发育于沪州赤水道真以南的台地相区。 - I also define each unite of formation and members . including characters of petrology and regional distribution . finally , the stratigraphical framework have been constructed based on consistencies of petrology , facies and the relationships of rock units
同时对所划的各组、段的特征、含义进行了详细描述，最后依据岩性岩相特征、地层接触关系等，进行了区域对比，建立了该区石炭系的岩石地层格架。 - At last the rhythm of yanshanian volcanic rocks is classified into three series such as alkaline basalt , hkca , calc - alkaline shoshonite . 4 . based on the study of rock series , assemblage of igneous rock , characteristic of geochemistry , trace effect of isotope , the yanshanian volcanic rocks of yanshan - liaoning area are mainly calc - alkaline series , which should belong to the products of near continental margin of intracontinental tectonic setting
3 、在火山活动节律的划分、区域对比的基础上，研究了各级节律火山岩的岩石学、矿物学、地球化学和同位素地质学特征，将研究区燕山期火山岩划分为碱性玄武岩系列、高钾钙碱性系列和钾玄岩系列。 - Through synthetically study , some achievements are made as follows : 1 . based on the application of sequence stratigraphy , for the first time the characteristics of sequence stratigraphy in the xicheng concentrated mineralization area are discussed systematically and 13 three graded imperfect sequences of devonian stratum are recognized . the result shows that hydrothermal sedimentary mineralized type and hydrothermal sedimentary - rebuilded mineralized type ore deposits occur in intergrade between two sequence , as well as occur in intergrade between highstand systems tract and transgressive systems tract
通过对该区矿床成矿作用的综合分析研究，取得了如下一些成果和认识： 1 )应用层序地层学理论，首次系统论述了该区泥盆系层序地层的特征，识别出13个不完整的三级层序，并进行了区域对比。层序地层分析发现海底热水沉积型矿床和海底热水沉积-改造型矿床的赋矿部位是两个层序的过渡部位，既高水位体系域向海侵体系域过渡。
