[2][9][10] The name 'euchlorine' comes from the Greek word εΰχλωρος meaning "pale green" in reference to the mineral's color, other reported spellings include euclorina, euchlorin, and euchlorite.

[2][13] Mineral associations at this site include dolerophanite, eriochalcite, chalcocyanite, melanothallite, anglesite, atacamite, cryptochalcite, palmierite, barite, and natrochalcite.

[16][17][18][19][20][21] At fumarole deposits in the North Breach from the Tolbachik Volcano eruption of the Great Fissure on the Kamchatka Peninsula euchlorine (as euchlorite) was found associated with newly discovered mineral avdoninite and reported around 2005–2007.

[17] Not long after, in early 2013, yaroshevskite was reported newly discovered from scoria cones of the Great Fissure Eruption at Tolbachik Volcano in association with euchlorine.

[19] Work conducted on fumarole deposits from the same eruption found euchlorine being associated with a newly discovered mineral called itelmenite and was reported in 2015 and published in mid to late 2018.
