辉石岩的微量元素地球化学特征及其深部过程 - On the basis of detailed and systematic studies on the petrography , major and trace elements and sr - nd isotopic data of mesozoic volcanic rocks , especially the mafic volcanic rocks in yanshan area , we successfully studied the deep processes related to magma generation and their relationship with shallow - level tectonic evolution . the major conclusions are summarized as below . 1
论文通过对燕山地区中生代火山岩，特别是中基性火山岩，进行详细而系统的岩石学、主微量元素地球化学特征和sr - nd同位素组成特征的研究，主要取得了以下研究成果： 1燕山地区中生代( j - k )火山岩为一套钙碱性-高钾钙碱性-橄榄安粗岩系列岩石。 - Based on the geological , stratigraphic and geochemical characteristics of the ophiolitic melange , island - arc and rift volcanic rocks from the jinshajiang zone , an archipelagic tectonic model with multi - rift and multi - subduction is proposed to explain the evolution of jinshajiang paleo - tethys . the ophiolitic melanges of the jinshajiang zone are mainly outcropped at baimangxueshan , tongduo , gongka , dongzhulin and jiyidu in the deqin county . the geochemistry of major and trace elements of the jinshajiang ophiolite shows its geochemical characteristics are similar to those of the more and island - arc volcanic rocks , but different from those of the typical n - mopjb
金沙江蛇绿混杂岩主要分布在德钦县的白茫雪山、通多、共卡、东竹林和吉义独地区，主量和微量元素地球化学特征研究表明，金沙江蛇绿岩不具有典型n - morb的地球化学特征，而具有介于morb和岛弧之间的地球化学特征，暗示它并非形成于宽阔的大洋环境，不是古特提斯在滇西北地区的主缝合带，可能是古特提斯多岛洋体系中的一个弧后盆地。 - This paper deals with the basic principle of applying trace element technique to near - surface oil and gas geochemical exploration , the classification of trace element observational methods , the oil - indicating significance of the criteria , the advance in the application of the trace element method to oil and gas exploration , and the development trend of the trace element geochemical researches
