This is a standard deverbal noun meaning the act or process of depositing.

Etymology

Deposition comes from the Latin parts de- 'down' and pose 'place', the same root you see in deposit and position. So a deposition in nature is literally 'placing down'—the act of material like ash, frost, or sand being left in one place.
