摘要主要論述了與早前寒武紀變質地層(學)有關的8個方面的問題:早前寒武紀變質地層的研究概況;早前寒武紀變質地層的復雜性和研究難度;早前寒武紀變質地層研究的思路和工作方法;早前寒武紀變質巖石地層單位巖群、巖組和雜巖的劃分問題;重要區域性不整合的研究;鑒定變質地層的原巖類型、巖石性質和恢復古環境;正確區分變質地層和ttg巖系以及其他變質深成巖;變質地層時代的確定。2 both the hanging wall and the footwail rock of ore bodies are garnet biotite schist, protoliths are alkaline volcanic rocks ( tracyh andesite ). according to characteristics of trace elements assemblages and the setting of tectonics, these alkaline volcanic rocks were derived from the lower degree melting of metasomatic and enriched mantle ( eml ) in the initial stage of middle proterozoic epoch. they strongly enriched in large ion lithophile elements ( lile ), such as ba
2 、礦體頂、底板圍巖(石榴石黑雲母片巖、鈉長黑雲母片巖等)的原巖為堿性火山巖(粗面安山巖) ,相對富集大離子親石元素ba 、 cs 、 rb 、 k 、 lree及貧zr 、 sr 、 ti 、 hf 、 hree ,為早元古代末期-中元古代早期交代富集地幔低程度部分熔融所形成的堿性火山巖。The pges abundance patterns of residual mantle rock with a peleo - subduction background is characterized by pd, pt depletion and ir, ru relatively enrichment, while the basalt and basic dyke by the processing of partial melt in the same background take an opposite feature of pd, pt enrichment and ir, ru depletion. the existence of fluid in the subduction zone increases the degree of partial melt on the one hand, and on the other, activates the activity of pd, pt compare to ir, ru, and thus reduces the pd ir and pt ru in residual mantle rock. the pges patterns for basalt and basic dyke from two carboniferous volcano zones to south qoltag and north turpan - hami basin, xinjing uigur autonomous region, take a shape of gentle positive inclined curve with lower pt and pd differentiation and lower pges. all these features are obviously different from that of basic dyke and basalt from typical ophiolite and therefore the author believe that their fluid - rich paleo - subduction zone environment can be ruled out
古俯沖帶背景下的殘餘地幔巖的pges配分以pd , pt明顯虧損和ir , ru相對富集為特徵,而部分熔融產物的玄武巖和基性巖脈則呈現相反的ir , ru明顯虧損和pd , pt相對富集特徵。俯沖帶中流體的參與一方面增加了部分熔融程度,有利於pd , pt從原始地幔進入熔融相另一方面,流體的作用使得pd , pt相對于ir , ru遷移活動性效率提高,造成地幔巖中According to sedimentary characteristics of the carboniferous taiyuan formation in feicheng coal field, including lithology, size distribution, sedimenta ry structure, geochemistry and paleontology etc., the carboniferous paleoenvironme nt of this area is divided into carbonate open platform and tidal flat environme nt. it is recognized that the taiyuan formation is formed in the epicontinental c oast which is dominated by the tidal. the peat flat is the important paleoenviron ment for coal accumulation. the tidal channel destroys the coal bed. the pulsative vibration of the crust is the major factor which controls the evolution of the sedimentary environment and the coal accumulation
