Research Plane Surveys Connecticut River Valley for Hazardous Mineral

A research plane has begun surveying the Connecticut River Valley to locate deposits of a mineral known as pyrrhotite, which poses significant risks to construction in the region. The initiative, led by the United States Geological Survey (USGS), aims to assess the impact of this mineral, which can cause structural weaknesses in cement and lead to the failure of building foundations.

The aerial survey focuses primarily on areas in Connecticut and Massachusetts, extending into portions of Rhode Island, Vermont, and New Hampshire. This effort is part of the USGS’s Earth Mapping Resources Initiative (MRI), which seeks to modernize the mapping of the country’s geological features, both above and below the surface.

Meghan Seremet, Connecticut’s state geologist, expressed enthusiasm about the survey, stating, “This survey covers a large portion of southern New England. It will provide new insights into Connecticut’s bedrock that wouldn’t be possible without modern geophysical tools.” The collaboration with Massachusetts and Rhode Island is expected to enhance mapping efforts along state borders, ultimately improving the understanding of geological hazards throughout the area.

The flights, which are set to continue through the fall of 2023, will launch from Robertson Airport in Plainville, Connecticut. The aircraft is equipped with advanced sensors capable of measuring magnetic fields and low-level radiation emitted by rocks. These measurements will facilitate the development of detailed three-dimensional geological maps, which are crucial for identifying both resources and hazards.

The USGS notes that the plane will operate at altitudes as low as 300 feet in some regions, making it easily identifiable by its long boom extending from the cabin. This equipment is designed to generate no emissions that would pose risks to humans, animals, or plant life. Importantly, no video or photography will be captured during the flights.

According to Jamey Jones, science coordinator for the USGS Earth MRI, enhancing knowledge of New England’s geological framework is essential for addressing national priorities, including earthquake and landslide hazards, as well as ensuring water availability. He stated, “By working together on this survey, Connecticut and Massachusetts are helping with the work of the nation.”

The results of this survey are anticipated to not only contribute to the understanding of local geological hazards but also support broader efforts in resource management and land-use planning across the region.
