Preferred Labelskos:prefLabel | feldspathic lithic detrital mode |
---|---|
Definitionskos:definition | Sandstone petrographic composition term indicating that detrital mode for clastic rock (Q-F-L) includes less than 75 percent quartz and the feldspar to lithic ratio is between 1 to 1 and 1 to 3. This corresponds to the feldspathic litharenite field of Folk (1968). Rocks in this class are likely to be quartzo-feldspathic in terms of mineralogical composition terms in this vocablary, but because the mineralogical composition of the lithic fraction is not constrainged, this correlation is not necessary. |
