feldspar n.【礦物】長石。

feldspathic

The feldspar of the reservoir sandstone in the study area consists of a higher percentage of na feldspar that of k . feldspar . the sandstone is composed of certain little rock fragments such as pyrite , mica , siltstone , mudstone , chert , and volcanic fragments 砂巖內長石由鈉長石與鉀長石組成,以鈉長石為主;巖屑由黃鐵礦、云母、粉砂質、泥質、燧石與火山巖屑構成。

Observed through sem , grain edge of clastic feldspar was broken into pieces because of dynamic consolidation . compared with samples of the same layer and location before and after tamping , grain diameter of tamped soil was attenuated 掃描電鏡下觀察土中較大顆粒的碎屑長石,強夯后顆粒邊緣出現破碎;對比強夯前后同一層位、同一位置的土樣,夯后土顆粒粒徑有細化現象。

Realm . e . feldspar s application : manufacturing potassium fertilizer , manufacturing porcelain and enamel ware , glass raw material , wheting the grain etc . . f . the barite primarily used for the artesian wells of petroleum and natural gas 麥飯石原巖本身多半由鉀長石斜長石石英等礦物組成,含有銅鋅鋁錳鐵鈦磷等微量元素,且又具有良好的溶出性和吸附性。

The determinative characteristics of common rock forming minerals containing quartz group , feldspar group , mica group , hornblende group , pyroxene group , olivine group and carbonatite minerals will be discussed in greater detail 對常見造巖礦物,如石英類、長石類、云母類、角閃石類、輝石類、橄欖石類、碳酸鹽類礦物的鑒定特征將予以詳細的說明。

A . the granite is made up of quartz , feldspar and mica . it has the high degree of hardness , bearing abrasion , anti - shake , ant - press . its color primarily contain deep ash and shallow ash , emerald green , rose red and blue 花崗巖是由矽石英長石和云母等細粒組成,具有高硬度耐磨抗震抗壓的特性。其?色主要有深灰和淺灰,翡翠綠玫瑰紅和蘭色。

4 . when the quartz fraction was cleaned of feldspar grains by etching in concentrated hf for 40min , more quartz fraction was etched away , and this method may be not suitable for the purity of quartz in loess 所以,黃土細顆粒混合礦物的blsl可能來自石英和長石, post - irosl與純藍光釋光信號(無ir暴露)相比,更富含石英的osl 。

4 ) the main reservoir of studying region is low pority , low peremeability litharenite and feldspar litharenite with the character of the low component maiturity and middle textural maturity . mostly the reservoir space is secondary pore 研究區儲層主要為低孔低滲的巖屑砂巖和長石巖屑砂巖,成分成熟度低,結構成熟度中等。

Minerals in deposit are made up simpler , the metal minerals are pyrite , chalcopyrite in second , and littler natural gold ; the veinstone minerals are quant , feldspar and carbonate 礦床礦石礦物組成較簡單,金屬礦物以黃鐵礦為主,其次為黃銅礦,有一定量的自然金;脈石礦物以石英、長石、鐵碳酸鹽為主。

The cementation of laumonite , calcite and chlorite , compact and pressure solution , as well as the dissolution of laumontite , feldspar are also of main factors which affect reservoir properties 方解石、綠泥石、濁沸石的膠結作用、壓實壓溶作用和濁沸石、長石的溶解作用也是影響儲集性能的主要因素。

The petrographic and xrd analysis reveals that the reservoir of the upper part of kongdian formation mainly consists of feldspathic and minor amount of lithic sandstone . the feldspar is consisting mainly of na 巖石學與xrd全巖分析表明,孔店組上段砂巖主要為長石砂巖,此外還發育少量巖屑砂巖。

Furthermore , the lunar orbiters confirmed that the highlands of the moon are dominated by anorthosite , an igneous rock composed primarily of the mineral feldspar and rich in calcium and aluminum 此外,兩艘月球軌道船證實了月球高地主要由斜長巖(一種主要由長石形成的火成巖,富含鈣和鋁)構成。

This stone is actually quite rare and difficult to cut , so in many cases other types of rock were used as substitutes , for example green feldspar , basalt , and serpentine 這個石頭實際上相當稀罕和難于切割,因此在許多情形里其它類型巖石被當作代用品使用,例如綠長石,玄武巖和蛇紋石。

The results indicate that the jade mainly consists of illite and a small quantity of feldspar , quartz , hematite , siderite and rutile , which is argillaceous sedimentary rock 結果表明,其礦物成分以伊利石為主,含有少量的長石、石英、赤鐵礦、菱鐵礦和金紅石,為泥質沉積巖。

Loess is silt - sized aeolian deposit and is mainly composed of quartz and feldspars , its osl signals can be set to zero by exposure to light 黃土作為一種風積物,主要礦物是長石和石英,光釋光信號在搬運漂浮于空中時可以被陽光曝曬“回零” 。

Hematite mainly occurs in cleavage cracks and microfissures of such minerals as feldspar , and the higher the hematite content , the deeper the red color 赤鐵礦主要賦存在長石等礦物的解理縫及其顯微縫隙中,赤鐵礦的含量越多,顏色越紅。

It is the most important gem of plagioclase clan to draw the feldspar , its captivating place is a color that can see the color spot form the gem 拉長石是斜長石族最重要的寶石,它的誘人之處是透過寶石面可以見到彩斑狀的顏色。

The products scope of chuanshi minerals processing factory : mica , vermiculite , quartz sand , colored grit , cobble , tourmaline , light calcium carbonate , feldspar , feldspar powder , marble , etc 靈壽縣川石礦產加工廠生? ?品范圍:

Big one draws feldspar and shows this kind of effect is best , called and glistenned to change colors , this is caused by one layer of forms structure 大塊拉長石顯示這種效應最佳,稱為閃光變彩,這是由于層狀結構引起的。
