AUTUNITE

Ca(UO2)2(PO4)2-10H2O
Hydrated Calcium Uranyl Phosphate


Turner Tin Prospect (New Ross), Lunenburg County
UTM (NAD27)
Zone 20
 Northing 4960150 / 4959950
 Easting 385160 / 385190
Details:
 The Turner Sn prospect is located along both sides of the east branch of Gold River at Mill Road, Lunenburg County. The prospect is accessible by trail from Mill Road (O'Reilly et al. 1982).

 NSMOD #A16-012
Further Info:
 Mineralization: Within the greisen, mineralization is disseminated in patches of phengite and quartz and/or associated with narrow, oxidized, iron-rich veins. Minerals identified include: arsenopyrite, pyrite, sphalerite, chalcopyrite, stannite, wittichenite, cassiterite and covelite. Digenite resulted from the alteration of chalcopyrite and sphalerite. High scintillometer readings were recorded from the Discovery vein, the mineral was assumed to be torbernite or metatorbenite (Ellsworth, 1950). The presence of autenite was suggested by the existence of a green fluorescing mineral in radioactive patches (O'Reilly, 1982).
Other Minerals:
 arsenopyrite, wittichenite, cassiterite, chalcopyrite, covellite, pyrite, sphalerite, stannite, torbernite

M.e.x. Uranium Showing, Hants County
UTM (NAD27)
Zone 20
 Northing 4964040
 Easting 425770
Details:

 The prospect is located in 2, side-by-side gravel pits found along a lumber road, approximately 500 m north of Christie Lake. Christie Lake is approximately 30 km northeast of Halifax and is immediately west of Big Indian Lake.

Further Info:

 The type and style of mineralization is similar to that at the Millet Brook Uranium Deposit, Hants County, Nova Scotia.
Finely disseminated U-bearing phosphates (torbernite and autunite), chalcopyrite and pyrite are associated with an extensively hematized northeast-trending, shear zone. The uraniferous zone extends for approximately 100 m along the shear.
Rock types exposed in the gravel pit encompass all phases of the Big Indian Polyphase Intrusive Suite. The wall rocks exhibit intense hydrothermal alteration, including high-alumina hydrothermal alteration as reflected by the presence of andalusite, cordierite, sillimanite, spinel, garnet, muscovite, biotite and tourmaline.

Other Minerals:
  chalcopyrite, pyrite, torbernite, sillmanite, andalusite
