Lapis Lazuli near Lake Harbour, Southern Baffin Island, Canada
Two lapis lazuli occurrences are present in marble near the cores of synforms near Lake Harbour, southern Baffin Island. The main occurrence covers an area of 3500 m 2 and contains 4 zones, the longest traced for 168 m. The lapis lazuli consists mainly of haüyne, diopside, plagioclase, and calcite i...
