According to Bobyarchick, Charlotte’s bedrock is typically more resistant to large sinkholes.
“Our bedrock is what we call metamorphic rocks, and these are rocks that have been buried deep in Earth subjected to high temperatures and pressures,” Bobyarchick said. “Many of our rocks have a lot of silicate minerals. And so, what that does is give us soils that are fairly high in clay content. And these soils tend to be impermeable or have to have low permeability.” Watch the segment at https://www.wcnc.com/article/weather/weather-iq/weather-impacts-sinkholes/275-eb29d6fd-289c-4004-b96a-1b0f3573995e.
