The chromite deposits in the muskox complex occur only in feldspathic peridotite . 在穆斯科克斯杂岩体中，铬铁矿矿层仅产于长石质橄榄岩中。

Preliminary tests and study on construction methods of building dams on feldspathic sandstone 砒砂岩筑坝施工方法初步试验研究
3.
The reservoir from the lower part of qiketai formation to xishanyao formation is mainly composed of feldspathic litharenite , which is the second lithologic section 七克台组下部-西山窑组储集层以长石岩屑砂岩为主，属于第二岩性段。
4.
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 岩石学与xrd全岩分析表明，孔店组上段砂岩主要为长石砂岩，此外还发育少量岩屑砂岩。
5.
The feldspathic sandstones belong to this formation of composite sources metamorphic , sedimentary , and igneous sources , but mainly from metamorphic source due to the high abundance of brown cl colors of quartz 上述情况表明，研究区长石砂岩物源母岩包括变质岩、沉积岩与火成岩，但从发育大量棕色石英颗粒来看，物源以变质岩为主。
6.
According to rock and mineral analysis , the formation consists dominantly of detrital feldspathic fine - sandstone with medium and silt sandstone secondly . lithologically , the content quartz is lower than those of feldspar and detritus , and the cement is dominated by clay , which gives the feature of low compositional maturity and low textural maturity 馆上段储层岩性以岩屑质长石细砂岩为主，其次为中细砂岩和粉砂岩，岩石中石英含量低，而长石、岩屑含量高，胶结物以泥质为主，表现出低成分成熟度和低结构成熟度的特点。
