胜利油田火山岩的岩浆网络及其意义 总被引:1,自引:0,他引:1
在前人工作基础上,研究了胜利油田火山岩岩浆网络特征,提供了胜利油田二氧化碳气藏与碱性橄榄玄武岩浆去气有成因联系的新证据。样品分别采自二氧化碳气藏区和非二氧化碳气藏区早第三纪的火山岩(潜火山岩)。选取了火山岩辉石中包裹体的棕色玻相、无色玻相和玻璃基质对其岩浆网络类型和断键程度用RAMANOR U-1000型激光拉曼探针进行了测定。然后对拉曼图谱进行处理,确定各玻相网络分子结构类型;再近似计算各玻相网络结构单元的相对摩尔百分含量;进一步算出各玻相的断键程度。结果表明,在岩浆演化的不同阶段其岩浆网络类型和断键程度是有区别的。随岩浆由早期向晚 相似文献

A great quartity of cosmic dust(spherules) was found in deep-sea sediments during May to July,1983manganese nodule investigations by the R/V“XIANGYANGHONG 16”in the area 7°-11°N,167°-178°Win the Pacific.Comprehensive study of the cosmic dust and determination with Laser Raman MolecularMicroprobe(LRMM) of the molecules in it showed that besides Fe-Fe,Fe~(3+)-O,Fe-Ni,Al-O,Fe-Obr-Si and Si-Onb,it also contained the organic molecules C-H-O and C-H-S-O,various no fixed form molecules of C,CH_2,CH_3 and volatile molecules CO_2,H_2O,OH~- and H_2S,etc…The study result has very important applications for exploring the origin of interplanetary dust parti-cles and life material. 相似文献
