PROCBBDIKGS OF SECTION C. 



(e) Solvshergite. — Fife's Range, Delaney's Creek road, near 

 Woodford. Dyke rock. 



Texture: Holocrystalline, fine grained, even, and microcrys- 

 talline, almost panidiomorphic, granular. 



Constituents : Orthoclase, anorthoclase, albite, acicular 

 segirines, magnetite, and interstitial quartz. 



(/) Paisanite. — Dyke near Beerburrum Railway Station. This; 

 is a beautiful orthophyric close-grained rock, very like the 

 Conowrin comendite in hand specimen, microscopic stnic- 

 ture, and composition. As it occurs as a dyke it may be 

 termed " paisanite,'' although it is not distinguishable 

 from orthophyric comendite. 



(cf) Monzonite. — Mount Cooroy. 



Texture : Holocrystalline, medium and uneven grained, allo- 

 crysts, iBgirines, magnetite, and interstitial quartz. 



Constituents: 01igoclase--andesine, albite, orthoclase, par- 

 gasite, faint greenish diopside, biotit'e, magnetite (titani- 

 ferous), zircon, and a little quartz and apatite. 



Magmatic Names. — The alkaline rocks analysed by me from- 

 Southern Queensland fall under the headings Alaskose (Conowrin),. 

 Kallerudose (Coolum), Liparose (Ngun-Ngun, Trachyte Range), Phleg- 

 rose (Beenvah), Nordmarkose (Beei-wah), Umptekose (Mount Flinders, 

 Little Liverpool Range, &c.), Pulaskose (Mount Flinders), Adamellose 

 (Mount Cooroy). 



Some very closely allied rocks fall under different headings in the 

 American classification. 



6. Glaxjcophake Schists. — In addition to the alkaline volcanic 

 rocks, we have in South Queensland considerable areas of glauco- 

 phane schists which are amongst the most beautiful of metamorphic 

 rocks, and consist principally of the soda-amphibole glaucophane. 

 These rocks occur at Mount Mee and on the Mary River slopes of the 

 Conondale Range. I am describing them in more detail in another 

 paper.
