The four Field Trips run for the year to date have been as diverse as the membership of the Society itself. The hard working Field Trip subcommittee provided participants with Guides to the planned Stops on each of the Trips.

The first trip, on January 25, to the eastern part of the Northern Range, was held jointly with the Field Naturalist Club. Of the fifty participants, just six were geologists and their observations and discussions on the geology and potential of the formations encountered were of great interest to the naturalists.

The second field trip was to the Fishing Pond coastal area and through the western part of the Central Range, to examine the Late Miocene and Plio/Pleistocene formations which crop out there. This trip was sponsored by corporate member, Schlumberger, who provided two mini-buses with drivers and refreshments for all. The trip was lead by Steve Geetan and John Scott, and thirty members .

The third trip for this year was lead by Francis Inniss and John Scott, and was held on May 2. The thirty participants parked in the Coast Guard compound at Chaguaramas and travelled by pirogue, first to Crondstat Island, to examine outcrops of the Laventille Limestone and to learn a bit about the barite processing operations of corporate member Baroid. The group then made two stops on Gaspar Grande to examine the only known deposit of natural fluorite minerals in Trinidad and to explore the limestone caves. The last stop was at La Tinta Bay for a quick look at the interesting geological structures and minerals, and for a rest and swim. A planned stop at the salt pond had to be aborted because of the difficulty in approaching the pond by either sea or overland, coupled with a time constraint. To say that the group had an interesting and enjoyable excursion would be an . We had a GREAT time.

The fourth trip was to the Goudron area with Carol Telemaque, Anthony Richardson and Steve Geetan as trip leaders. The group of twenty-four participants examined sedimentary structures and subtle structural features in the younger sandstone sequence in the Goudron field (such as those shown in this photo taken by Steve Geetan), as well as a modern analogy, a sand deposit in the Pilote River, Guayaguayare.

The planned trip to Trinidad and Venezuela, run by Sam Algar and Jim Pindel, came off on June 4-9, 1992. Over twenty participants, local and foreigners, took part in two days of field work in Trinidad and three in Venezuela. Several GSTT members were in the field party and Steve Geetan took his usual excellent photos for our records. The GSTT's own plans for a trip to Eastern Venezuela fell through because of a lack of support, se we were pleased that some members could benefit from this trip.

The next planned local trip is scheduled to be another excursion in the Central Range area to see outcrop sections of the early Tertiary formations, which we have not examined recently. Circulars will be sent out when arrangements are finalized.
