This map presents the field observations and initial geological interpretations for the Pond Inlet area (part of NTS 38-B), Baffin Island, Nunavut. The bedrock geology comprises Archean tonalitic to monzogranitic gneiss that includes minor mafic to intermediate components, and relatively homogeneous monzogranite-granodiorite intrusions. The Archean Mary River Group forms discontinuous volcano-sedimentary belts, consisting of mafic volcanic rocks interlayered with siliciclastic strata, banded iron-formation, and felsic to intermediate and ultramafic volcanic units. The supracrustal rocks are intruded by monzogranite-granodiorite plutons. Pre-Mesoproterozoic rocks record a complex structural history involving at least two regional deformation events and mineral assemblages indicate metamorphic conditions ranging from upper-greenschist to granulite facies. Mesoproterozoic clastic and carbonate platform sequences of the Bylot Supergroup unconformably overlie Archean units in the central part of northern Baffin Island. These strata were deposited within a graben that forms part of the larger Borden Basin.
