Oct 21-24th, 2004, Dr. Norman Duke and
7 students in the
UWO SEG chapter went on a field trip to the Grenville
province in order to get a better perspective on the Grenville
and Rhodinia in planning the Grenville short course. The trip
transected the Adirondack Highlands across the Central
Metasedimentary Belt, from New York to Southern Ontario. |

October 22 saw the group touring open pits with J.
Kreider of Grouveneur Talc to observe stratigraphy, mineralogy and
shear structures. The afternoon was spent receiving a presentation
from Bill DeLorraine of St. Lawrence Zinc on the on interpreting the
structural complexities of the Sedex – style, structurally
controlled Balmat mine. Many thanks go out to these industry people
for allowing us the opportunity to gain their insight. |

Additional stops were made on road cuts to observe
stromatolites, marbles, migmatites and gneisses.

October 23 the
group drove deeper into the Tweed-Madoc
area to observe ilmenite/hematite - bearing anorthosite
bodies and giantism around the Bartin Garnet Mine.
 |
 |
| October 24 was spent transecting the geology of the
Central Metasedimentary Belt from Kaladar to Madoc, moving north
into Southern Ontario just south of Bancroft to look at Marmora open
pit iron oxide mine and a nepheline syenite body.
Special kudos to Dr. W. Church for setting up many maps and GPS
points that took the guesswork out of navigating in the Adirondacks.
