Fluid Inclusion Laboratory (FIL)

Halite bearing fluid inclusion from the Snowbird REE Deposit, Montana

Fluid Inclusion Laboratory - INCO Innovation Centre (FIL-IIC)

Fluid inclusions are micron-scale fluid-filled cavities in or between rock crystals. They are samples of fluid trapped during geological processes. Analysis of these inclusions can provide fundamental physiochemical information on the fluids responsible for economic accumulations of oil and gas, as well as many mineral deposit types.

Fluid Inclusions in Petroleum Exploration

• Used to trace aqueous and hydrocarbon fluid flow, and reconstruct pressure-temperature-density (PVT) conditions of fluid trapping
• Can define petroleum migration pathways and paleoresevoirs in oil wells that have otherwise recorded no presence of oil.

Fluid Inclusions in Mineral Exploration

• Provide information on ore transport and depositional processes
• Facilitate estimates on the temperatures and pressures of mineralization
• Suggest correlations with other mineral deposits, important for the development of exploration strategies .

The fluid inclusion laboratory in the Inco Innovation Centre consists of a Linkam THMSG600 heating freezing stage, mounted on an Olympus BX51 microscope outfitted for use with reflected- and transmitted-visible and ultraviolet light using 4x, 10x, 40x and 100x Olympus long-working distance objective lenses. This system allows phase transitions to be observed in fluid inclusions over the temperature range of -193 to + 600°C. Digital images of fluid inclusions are captured using an Olympus DP71 camera. Linkam THMSG600 heating freezing stage and Olympus BX51 microscope purchased by Pan Atlantic Petroleum Systems Consortium (PPSC). Rock thin sections and doubly polished fluid inclusion wafers are prepared at Memorial University.
