The albite component increases while anorthic component decreases in detrital plagioclase.The plagioclase turned into an end - member component of albite.
Latites contain plagioclase feldspar (andesine or oligoclase) as large, single crystals (phenocrysts) in a fine-grained matrix of orthoclase feldspar and augite.
The Shuangwang gold-bearing albitite zone, which is composed of stratabound albitite, albitite breccia occurred conformably in the Xinghongpu Group, Devonian silt-slate.
Albite and labradorite both belong to plagioclase series, but they are the two different varieties.According to the characters of inclusion and transparency, iridescent ...
The middle oil-member is characterized by medium-sized sandstone and pebbled sandstone, with fair sorting and subangular sphaericity.Rock types mainly were feldspar debris sandstone.
Therefore, the albitization of plagioclase is shown in the early stage of diagenesis and albitization of potash feldspar appears only in the late stage of diagenesis.
" The properties...of moonstone...and its uses...in potion-making..." , he muttered, writing the words across the top of his parchment as he spoke them. " There."
Binns set us a foot-and-a-half-long essay on giant wars, Snape wants a foot on the use of moonstones, and now we've got a month's dream diary from Trelawney!
