Question for geologists/explorers

[Shaele]

Doing exploring runs I have noticed a lot of landable planets seem to have a high arsenic content (according to EDDI) and just wondering if that was true and why.

It may be confirmation bias but just sees a lot of planets have arsenic on them more than other ingredients

Check for volcanic activity, hot like iron magma not cold like nitrogen magma. A lot of arsenic is released into the environment on earth by volcanic eruptions, most of the rest by leaching from crystals water soluble rock so I wouldn't expect an icy planet to have much around on the surface, however if it has a large component of rock the scanner may be picking up arsenic locked away in salts and crystals and rock formations.
