STRUCTURAL DATA
Structure type | Strike | Dip | Separation |
---|---|---|---|
schistosity | 15 | 68 |
Rock Number | Type | Width (m) | Strike | Dip |
---|---|---|---|---|
0 | Molson dike | 0.00 | 71 | 69 |
-this particular dike appears to be of the NORT composition suite
-the sample is from around 15 cm from the footwall
PETROLOGIC DATA
Rock Number: 1
-grey weathering, PORT, well foliated, slightly sheared GRDR
-10% white MC phenocrysts up to 6 mm
-excellent preservation of the old fabric with its intendent beige pegmatitic lee
-this old fabric has been warped into the 050, probably in this location a drag along a fault
-this rock is a good example of CWB-WJC-GRDR
Rock Number: 2
-foliatied high - MG Molson dike
-NW shore of this channel has almost continuous exposure of typical grey-brown weathered DIBS
-this has a strong fabric at 069 but slightly inconsistant
-there is only 3 metres of thickness exposed but grain size continues to increase to the south east and th opposite shore shows extensive HM-pinking of joint surfaces which suggests th dike may have a possible thickness of up to 45 meters thick
-fairly obvious that this section of the stream is controlled by the Molson, (see notes...con't)
