Guide des excursions au Canada1-10 . sur le lot 32 de Con. Ill, canton de Glamourgan. Cette syénite néphéline, qui est exposée sur la route, est très fraîche et représente une varietypétie qui est très distinctement foliée et sombre en couleur.Néphéline et hornblende preponderate en grande partie dans le therock, le feldspath étant subordonné en quantité. Thehornblende a les propriétés optiques de hastingsite et le feldspath est albite. La roche contient également quelques grains de calcite, arrondis sous forme et se produisant comme inclusions dans les autres constituants de la roche. Ils ne sont manifestement pas d'origine secondaire, mais sont semblables en ch

Guide books of excursions in Canada1-10 . on lot 32 of Con. Ill, Glamorgan township. This nepheline syenite, which isexposed on the road, is very fresh and represents a varietywhich is very distinctly foliated and dark in colour.Nepheline and hornblende preponderate largely in therock, the feldspar being subordinate in amount. Thehornblende has the optical properties of hastingsite and thefeldspar is albite. The rock also contains some grains ofcalcite, rounded in form and occurring as inclusions in theother constituents of the rock. They are clearly not ofsecondary origin but are similar in character to those foundin the nepheline syenites in other parts of the area asalready described (see pp. 58-62). An anlaysis of the rock by M. F. Connor of theDepartment of Mines is given en page 96). 77 Miles andKilometres Annotated Guide (Continued).Bancroft.

Nepheline syenite from lot 32, Con. VI, Glamorgan township, showing biotite, nepheline andmicrocline, with two included grains of calcite. with some included masses of crystalline lime-stone. The original hastingsite was found inthe nepheline syenite near this road about 2miles (3-2 km.) from Bancroft. The latterpart of this journey, after leaving the main 78 road (about 5-5 miles (8-8 km.) from Bancroft), is through the old Egan or Bronson farm, an oldlumber depot and farm owned by the lumberingfirms whose names it has borne. It is nowknown as the Lancaster farm, from the name ofits present owner. A now deserted lumberroad connects the farm buildings with the oldcamping ground on York river still known asBronsons Landing. 410-37 m. Bronsons Landing.
