Geology Comments

Dec 07, 2005 (P Beach) - Radioactivity is associated with a zone of calcite-hematite stringers within a NE-trending Keweenawan diabase dike. The radioactive zone, 10 to 12 feet wide, trends nearly at right angles to the diabase dike and extends for about 15 feet into granite on each side. (OGS 1983 MDC 25 P 62).

Lithology Comments

Dec 07, 2005 (G Bennett) - Quartz-biotite-gneiss: Quartz 50%, Biotite 35%, Plagioclase 15% The rock is light to dark grey in colour and fine to medium grained. Parellel bands of thin leaves of biotite alternate with layers of quartz and plagioclase approximately 0.5mm to 2mm thick. This rock is bedded, the individual strata being from a few inches to 3 or 4 feet thick. White granite: Plagioclase 50%, Quartz 35%, Biotite 15%, Sulphides 1% The rock is fine to coarse grained, greyish-white, hypidiomorphic, equigranular, aggregate of the component minerals which grades into coarse pegmatites composed of quartz and plagioclase in proportions variable from place to place. Ultra-mafic: Ferromagnesian Mineral 100%(probably an amphibole) The rock is dark green to black, exceedingly coarse grained, hypidiomorphic and equiangular. It has been considerably altered, perhaps to talc or serpentine, as indicated by its softness. Adjacent to pink granite masses the rock has been altered by the addition of pink feldspar. Pink Granite: Quartz 30% Pink Feldspar 40%, plagioclase 10%, ferromagesian minerals 20%. Diabase: Ferromagnesian minerals 60%, Feldspar 40%. Orthoclase gabbro or Metadiorite: Ferromagnesian 65 to 75%, Pink Feldspar 25% to 35%, and Sulphides (very minor).

Date: Sep 07, 1999

Geologist: G Bennett

Notes: The original discovery of radioactivity on the Jupiter claims is found in a shear zone crossing a diabase dike which strikes N 80E. A small fault offsets the dike about 10 feet just east of he shear. Strong Geiger counts are found across the whole zone but especially in the north end where large calcite stringers occur. These calcite stringers have been broken up in places and form a breccia surrounded by thin layers of blackish material which is quite radioactive in spots. The whole shear area is red stained and hematite is present in small stringers and finely disseminated throughout.
