resorption

[rē′sȯrp·shən]
(petrology)
The process by which a magma redissolves previously crystallized minerals.
(physics)
Absorption or, less commonly, adsorption of material by a body or system from which the material was previously released.

Resorption

 

(1) In physiology, repeated assimilation; the same as absorption.

(2) In pathology and pathological physiology, the same as resolution. In cases of leukoses, for example, resorption of the bone develops very intensively and is accompanied by rarefaction and the complete resolution of the bony frame.
