钠长石

Dawsonite is an orthorhombic, hydrated sodium aluminium carbonate appearing as radial, bunchy, trichoid platy collective and so on, filling in the pores among the grains, or as replacement of feldspar and detritus partly or on the whole, dawsonite is a kind of authigenic mineral which formed latest.

片钠铝石是一种斜方晶系、含水、钠和铝的碳酸盐矿物，砂岩中的片钠铝石是最晚形成的自生矿物之一，一般以放射状、束状、毛发状、板状等分布于砂岩的孔隙中或交代长石和岩屑等。

Dawsonite in the shapes of foliated columnar, cluster, radial, chrysanthemum or random hair mainly filled in the intergranular pores as cements and a few replaced grains such as feldspar and quartz.

其中，片钠铝石呈板柱状、束状、放射状、菊花状、杂乱毛发状集合体，主要作为胶结物产于碎屑岩碎屑颗粒间的孔隙中，少量交代长石、石英等碎屑。

Actually, the term feldspar refers to a group of closely related minerals which have generally similar composition and characteristics.

严格地说，长石这个名称指的是成分和特征大体相似的一组有密切关系的矿物，它们是钠、钾、钙的铝硅酸盐类。

Any of a group of abundant rock-forming minerals occurring principally in igneous , plutonic, and some metamorphic rocks, and consisting of silicates of aluminum with potassium, sodium, calcium, and, rarely, barium.

"任何一组由大量岩石形成的矿物，主要存在于火成岩、深成岩以及一些变性的岩石中，含有钾、钠、钙及极少的钠的铝硅酸盐，地球的外层地壳中约百分之六十是长石。"

Any of a group of abundant rock-forming minerals occurring principally in igneous, plutonic, and some metamorphic rocks, and consisting of silicate s of aluminum with potassium, sodium, calcium, and, rarely, barium.

"任何一组由大量岩石形成的矿物，主要存在于火成岩、深成岩以及一些变性的岩石中，含有钾、钠、钙及极少的钠的铝硅酸盐，地球的外层地壳中约百分之六十是长石。"

Any of a common rock-forming series of triclinic feldspars, consisting of mixtures of sodium and calcium aluminum silicates.

斜长岩三斜晶长石系列中一种普通的成岩石，由钠和钙铝硅酸盐组成

The feldspar in A-type granite is perthite, the dark alkali-minerals in which are arfvedsonite or manganese-bearing magnesia- arfvedsoniteand aegirine.

碱性花岗岩中的长石为条纹长石，暗色矿物为钠铁门石或含锰镁质钠铁门石及霓石。

The feldspars from the γA1 and γAIIa show many clear metasomatic alteration features; the- refore, the authors genetically consider the albitized protolithionite granite and the albitized zinnwaldite granite to be metasomatic altered granites.

花岗岩中长石具有清楚的交代特征，晚期岩体中的钾长石的An和Ab组份十分低，斜长石中的An和OI组份也很低，说明钠长石化黑鳞云母花岗岩和钠长石化铁锂云母花岗岩为交代蚀变花岗岩。
