THE MINING AND QUARRY INDUSTRY I9II JI 



of the properties formerly owned by Moore Brothers and the 

 Ausable Granite Co., controls a large acreage of the syenite and 

 anorthosite in that vicinity which as yet is only partly developed. 

 The syenite quarries lie on both sides of the Ausable river, the more 

 important property covering the ridge which lies north of the river 

 and just east of the village. This is an excellent situation, both for 

 economic extraction and shipment. The syenite is of medium grain 

 and has a bright green color on polished surfaces. It is composed 

 mainly of alkali-feldspar and magnetite. It is particularly adapted 

 for monumental work, taking a lustrous polish and showing the 

 finest tracery in strong relief. It is sold under the name of " Adi- 

 rondack green granite." The company has a second quarry on the 

 west side of Ragged mountain, south of the river, where the rock 

 is of finer grain and darker color. This is marketed as " Killarney 

 green granite." The anorthosite properties are situated south of the 

 village on the ridge along the east branch of the Ausable. This has 

 been opened only in one place, the Wienholz quarry, from which 

 some building stone has been shipped. The anorthosite belongs to 

 the border phase, having a fine ground mass of crushed feldspar 

 which lends a medium gray tone to the rock as seen in large samples, 

 whereas the characteristic Adirondack type has a very coarse texture 

 and dark gray or green color. The light body is set off by inclusions 

 of black pyroxene and hornblende, with an occasional fragment of 

 dark uncrushed feldspar showing the iridescent play of colors 

 peculiar to labradorite. The color effect of the rough and dressed 

 surfaces is about that of a medium gray granite, for which it is an 

 all-round substitute. Owing to its simple mineral character the 

 anorthosite has superior fire- re si sting qualities, an important con- 

 sideration for some purposes. It is no doubt a strong and durable 

 stone. 



The syenite quarries owned by F. G. Carnes of West Chazy are 

 situated just south of Ausable Forks. The Keystone lies near the 

 base of Ragged mountain and yields a green syenite of lighter shade 

 than that from the quarries at a higher elevation. The Emerald 

 quarry is situated on the westward continuation of the exposure 

 across the river. The stone from this locality is a medium dark 

 green and rather fine in texture. Both afford excellent monumental 

 material. 



Another syenite quarry, known as the Clements quarry, is 

 situated on the side of Ragged mountain overlooking Ausable Forks. 

 It has shipped some monumental stock.
