Quentin mine
practically parallel to the strike. Felix ore is about seven
acres and is divided into 2 parts by 2 small headlands. There
has been considerable disturbance in this core. The eastern
part has the structure of a syncline and is formed of the
laminated series seen at Drum of Drum Core. In the middle
part of the core the lower 40 feet of the laminated series is
repeated by a fault running N.70 E. and dipping 70 S.
50 W. showing a distinct drag indicating that the west
or hanging wall has gone down.
"All the beds in this core show effects of metamorphism
in them, the schiel is darker reddish than normal. [To John:
whether this change appeared to be due to pressure fracturing my mind,
and then the aerial status deposited the iron in the course of the process]
"The laminated beds are here cut off by another fault run-
ing N.70 E and dipping about 75 S.20 E, with a heavy drag
and much fracturing of the footwall showing that the west wall has
come up. This brings to view 50 feet of loose shales. These are dark
and red and in bands 1/2 inch or so in thickness. The surfaces of
these bands have a sort of metallic film and they are nearly
covered with fine ridges little markings, mist mud cracks and ripples.
"Below these layers and as traveling on to the outer edge of
Felix Core is exposed about 120 feet of stiff brown shales con-
sisting of reddish sandstone in thin beds alternating with some
thinner bedded lagers. These are marked at various levels.
