Which of the following would NOT be considered an expected origin of a mercury deposit?

Mercury deposits typically form through specific geological processes that facilitate the concentration of mercury mineralization. The origins that are commonly associated with mercury deposits include epithermal, which involves the formation of minerals from heated water rich in mercury and other elements, and volcanogenic, which relates to the release of mercury during volcanic activity that can deposit it nearby.

Clastic sedimentation refers to the process where sediments are transported and deposited. While sedimentary processes can sometimes lead to the accumulation of minerals, they do not directly contribute to the formation of mercury deposits, which requires more specific conditions for mercury concentration and mineralization.

On the other hand, weathering can release mercury from parent rocks but does not typically lead to the establishment of significant mercury deposits in a concentrated manner. Therefore, it’s less of a direct process for forming deposits as compared to the other origins typically associated with the concentration of mercury.
