88 notes on some minerals. 



Chabazite. 



At Ben Lomond (N.E.), in rhombic crystals (like figure 6) in 

 cavities in amygdaloidal basalt, with other zeolites and calcite. 

 Colourless and transparent when moist, usually white and opaque 

 when dry. Occurs with other zeolites in the basalts about 

 Emmaville. Phacolite is found in isolated crystals, in basalt, 

 near the bridge at Inverell ; translucent, friable (in forms like 

 figure 7). 



Analcite. 



At Ben Lomond (N.E.), in trapezohedra grouped together in 

 druses, or lining the walls of cavities in basalt. Crystals generally 

 very perfect. Colourless, sometimes massive and opaque. Occurs 

 also in the vesicular basalts of the Emmaville District. 



Laumontite. 



Fifteen miles from Tarn worth, in Old Goonoo Goonoo Creek, a 

 quarter-of-a-mile above crossing of the road to Thos. Blevin's farm, 

 in vein in fossiliferous rocks. The vein is about two inches in 

 width. Colour, creamy tinted, opaque, pulverulent, very few 

 crystals. Also two miles from James Swain's farm, seven miles 

 S.E. from Carroll (Liverpool Plains), in veins in calcareous slates 

 with stilbite and calcite ; creamy white, opaque, good crystals 

 though small. 



At Werris Creek, crystallized ; in small veins with stilbite in 

 trap rocks (forms like figure 11). Crystals not common, usually 

 amorphous. 



Stilbite. 



At Werris Creek in nodular deposits, and in crystals in 

 amygdaloid, also in veins, associated with, and often enclosing, 

 white opaque calcite. Crystals like figure 10 but small, not more 

 than £ inch in length. The nodules exhibit a very perfect 

 cleavage, and a pearly lustre. Colour, pale flesh red, to yellowish 

 white, and nearly colourless. Transparent in thin laminae. Some 

 of the uncrystallized mineral may be heulandite. 



Near James Swain's selection, seven miles S.E. from Carroll 

 (Liverpool Plains), in veins, near rocks containing marine fossils. 

 Often inclosing nodular masses of white calcite. Crystals small. 



At Walcha Road, Great Northern Railway, near railway 

 station, in veins in decomposing granite. Crystals radiately 

 compacted, but often with free terminations. Colour, pale buff, 

 greyish, or nearly white translucent or opaque, pearly lustre, 

 friable ; common.
