本文就该矿床区域地质、矿区地质、矿床地质及矿床的同位素地质学、成矿条件和矿化规律、矿床成因类型等进行了阐述和讨论。 - 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。 - By studying the ancient barrier lake sediments , this paper mainly probes into the ancient climate evolution rule of more scale and less from twenty - two thousand to ten thousand years before present , diexi , minjiang river . moreover , influences to lower reaches of minjiang river is simply discussed because of die out of the ancient barrier . the using correlative theories in this thesis are mc chronology , sedimentology , isotope geology , environmental geology , geomorphology
本论文运用~ ( 14 ) c年代学、沉积学、同位素地质学、地貌学等学科的有关理论，通过对岷江叠溪古堰塞湖湖相沉积物的研究，采用沉积物碳酸盐碳氧同位素等多环境代用指标，研究岷江叠溪地区距今约22千年10千年古气候演化规律，讨论了古堰塞湖形成演化过程与地质环境的相关性。 - After the volcanic eruption of multi - phrase cycle - deformation , filling of basin , crustal uplifting event being studied , this dissertation tries constructing the different degree rhythm of magma activity corresponding with crust - mantle dynamic system , studying the crust - mantle deep processes . based on the studies on the characteristics of volcanic rhythm , igneous rocks assemblages , temporal and spatial distribution of igneous rocks , tectonic deformation , the author has util ized the methods of petrology , geochemistry , isotopic geology et al . to do research on the above - mentioned geological problems
通过多次幕式火山喷发-构造变形-盆地充填-地壳隆升事件序列的厘定，从火山活动节律特征、火成岩构造组合类型、时空分布及其演化和构造变形的历史记录，利用岩石学、地球化学、同位素地质学等方法，反演深部过程与浅部响应等来阐明造山过程，建立与不同级别岩浆活动节律对应的壳幔动力学系统，追索壳幔深部过程，已成为当今地球动力学研究的前沿课题之一。
