granitoid adj.花崗巖狀的;有花崗巖結構的。

granivorous

The main element analysis of whole rocks , the ree analysis and the trace element analysis have been done for the granitoid samples in this area . the chemical composition analysis has been done for the amphiboie and biotite minerals . the epma and x - ray powdered crystal diffraction have been done for k - feldspar , plagioclase , amphiboie , biotite , quartz , magnetite , titanite 對本區花崗巖類樣品進行了全巖主量元素、稀土元素及微量元素分析,對角閃石和黑云母單礦物進行了化學成分分析,對鉀長石、斜長石、角閃石、黑云母、及石英、磁鐵礦、磷灰石和榍石進行了電子探針和x射線粉晶衍射分析。

Comparing with the granitoid from jiaodong guojialing in mineralogy , the minerals in the granitoid in nimu - qushui granitoid crystallized in the environment of oxidization , the granitoid has a characteristic of rich volatile components and a high content of alkali , the rock - forming minerals and accessory minerals have a characteristic of i - type granite , and the granite shows a characteristic in favor of an and cu ore formation 通過與膠東郭家嶺地區的花崗巖類的礦物學進行對比,可知本區花崗巖類礦物結晶時處于氧化狀態,具有富含揮發分的特征,堿質含量高,造巖礦物及副礦物表現出型花崗巖特征,具有殼幔混源物質,表現出有利于金、銅礦形成的花崗巖類的礦物特征。

On the paas - normalized plots , the parent granite and the granite weathering crust are enriched in lree without ce anomaly . while the groundwaters are also enriched in lree , they display significant negative ce anomaly , indicating the fractionation of ce during water - rock interaction . based on the study of two profiles of granitoid weathering crust , we concluded that ree concentrations in the groundwaters from the granitoid weathering crust are likely related to the continued chemical weathering , as well as the ree concentrations in the crust near the water table , clay concentration and the wate r ph values 地下水與母巖、風化殼稀土的paas標準化分布模式基本相似,呈lree富集型,母巖中無ce異常,而水樣中有ce負異常,表明ce在水巖作用過程中發生明顯的分異;通過研究兩個典型花崗巖風化殼剖面發現,地下水的稀土含量與連續的化學風化,以及水位附近剖面上的稀土含量、粘土礦物含量以及水的ph值等有關。

The microscopical observation proves that the main types of granitoid rocks are granodiorite and quartz monzodiorite , and the enclave is mainly monzodiorite . the rock - forming minerals are mainly k - feldspar , plagioclase , amphiboie , biotite , quartz , magnetite , titanite , apatite , epidote , etc . the zonation of the feldspars is very popular . the dark - colored minerals , such as biotite and titanite , have been highly oxidized 通過對本區花崗巖類樣品進行顯微觀察研究,知其主要的巖石類型為花崗閃長巖、石英二長閃長巖,其中的巖石包體主要為二長閃長巖,其造巖礦物為鉀長石、斜長石、角閃石、黑云母、石英、磁鐵礦、榍石、磷灰石和綠簾石等,長石中環帶現象比較常見,黑云母、榍石等暗色礦物顏色較深,表明其氧化程度較高。

2 . 6 2 . 7ga , these granitoids are most likely to be derived from the partial melting of hybrids both 2 . 6ga metavolcanic materials in archean wutaishan magmatic arc and older continent crustal materials under lower than 1 . 2gpa . petrological and geochemical characteristics of wangjiahui granitoid intrusion suggest that is probably fored under post - collisional tectonic background 2 . 1ga在- 3 . 82 - 2 . 80范圍,表明王家會古元古代花崗巖最有可能形成于大約2 . 6ga五臺山大洋島弧火山巖物質和更老的陸殼物質在

The present lake wall of stone and granitoid was not then in place , but the road had been well laid out , the intermediate spaces of lawn were lovely to look upon , and the houses were thoroughly new and imposing 在北區沿著現在的北湖濱路已建起了一批漂亮的府郟那個湖當時還沒有用石塊和花崗巖鋪的湖堤。井然有序的道路把草坪分隔成一塊塊的,看上去很悅目,簇新的府第十分氣派宏偉。

Our results indicated that ree concentrations of groundwater within the granitoid weathering crust in baisha area are high relative to many groundwater samples within granite weathering crust worldwide 研究結果表明,白沙地區花崗巖風化殼地下水的稀土含量偏高,最高達到114 g / l ,比世界其他地區高1 - 2個數量級。
