Three types of subvertical pegmatitic leucogranites and pegmatites populate the Red Cross Lake pegmatite field, located in a greenstone belt of the Sachigo Subprovince, Manitoba, in the northwestern part of the Archean Superior Province of the Canadi

Liddicoatite, a rare species of tourmaline, has been found in the McCombe pegmatite, of complex type and spodumene subtype, an example of the LCT (lithium, cesium, tantalum) family. It is one of a group of beryl- and complex-type pegmatites exposed a

Rare-element pegmatites may host several economic commodities, such as tantalum (Ta-oxide minerals), tin (cassiterite), lithium (ceramic-grade spodumene and petalite), and cesium (pollucite). Key geological features that are common to pegmatites in t

Wet-chemical analyses (41) of tourmaline from granitic pegmatites (barren, barren-pocket, beryl, lepidolite types) in the Moldanubicum, Czech Republic revealed that members of the oxy-subgroup ĄV common oxy-schorl, minor oxy-dravite and rare oxy-foi

Les exemples de phosphates contenant le beryllium sont rares, et limites aux pegmatites granitiques et, de facon exceptionnelle, aux granites enrichis en elements rares. Une cristallisation primaire semble tout-a-fait inhabituelle. Au contraire, la p

The classic petalite-subtype Nykopingsgruvan pegmatites are located on the northern part of Uto Island, Stockholm archipelago, Sweden. They consist of two genetically related pegmatite bodies, the southern (minor) and northern (major), transecting th
