← ScienceWhich mechanism causes carbon-14 dating inaccuracy near volcanoes?
A)Fractionation alters isotopic concentrations
B)Volcanic ash increases beta emission
C)Magma outgasses old carbon dioxide✓
D)Lava flows metamorphose organic material
💡 Explanation
Volcanic activity releases carbon dioxide depleted in carbon-14 through degassing of magma. This dilutes atmospheric C-14, leading to underestimated ages via isotopic dilution, because measurements assume a constant atmospheric C-14 ratio rather than localized changes.
