To quote the Wikia articles about Spark mechanics:

"Cross-Spark (also known as ☓-Spark) is when two or more Omni Rarity units of the same element reach a damage distribution of 150% when sparked. Cross-Sparking will also provide buffs for the squad known as Resonance."

Resonance lasts 2 turns and grant various mono-elemental buffs, such as tristat boosts and damage reductions. I'll leave a link to the full article (Mid-Right) here.

I hope this helped! (^^)/
