补充资料:斜长石
斜长石 plagioclase 由钠长石分子Na[AlSi3O8]和钙长石分子Ca[Al2Si2O8]两种组分(前者用Ab表示;后者用An表示)组成的类质同象系列矿物的总称。按两种组分含量比例的不同分为6个矿物种:钠长石(An0~10 Ab100~90)、奥长石(又称更长石,An10~30 Ab90~70)、中长石(An30~50 Ab70~50)、拉长石(An50~70 Ab50~30)、培长石(An70~90 Ab30~10)和钙长石(An90~100 Ab10~0)。按它们的SiO2含量由高到低还可划分为酸性斜长石(前2种 )、中性斜长石(中长石)、基性斜长石(后3种)。斜长石的成分还常用所含An组分的摩尔百分数表,称为斜长石的牌号。如成分为An18 Ab80的奥长石,其牌号为18。许多斜长石晶体的内核与外缘的牌号不同,形成环带状斜长石。斜长石属三斜晶系,晶体呈板状或扁柱状。聚片双晶极为常见,晶面及解理面上有的可见双晶条纹。集合体呈粒状或块状。白色至暗灰色,玻璃光泽,莫氏硬度6~6.5,比重2.61~2.76。鉴别需借助偏光显微镜。斜长石占全部长石总量的70%,是构成火成岩的最主要矿物。不同种的斜长石分别存在于酸性、中性和基性火成岩中;钠长石是碱性火成岩的重要矿物成分。较高温度、较迅速结晶条件下形成高温斜长石;反之,则形成低温斜长石。 |
