Morphology
The meaning is directly compositional: 'carbon' names the element and 'dating' denotes determining age, so the phrase literally means dating using carbon. This noun+noun method-denoting pattern is common cross-linguistically (e.g. Spanish datación por carbono) and a B1 learner who knows both constituents would readily infer the MWE's meaning.
Etymology
The noun carbon dating comes from a simple idea: living things take in carbon, and when they die that carbon slowly disappears, so by measuring how much is left scientists can date the object and learn its 'age'.
