...Bradley L. Jolliff; James J. Papike; Charles K. Shearer Abstract Tourmaline occurs as an accessory mineral in five of six zones in the Li-, B-, Be-, Nb-, Ta-, and Sn-enriched, internally zoned Bob Ingersoll No. 1 pegmatite located in the Precambrian core of the southern Black Hills near Keystone...

... of the pegmatite system. The consequence of interaction between pegmatite-derived fluid and quartz-mica schist surrounding selected Black Hills pegmatites (Etta, Bob Ingersoll No. 1, and Peerless pegmatites) is alteration of primary metamorphic mineral assemblages to secondary mineral assemblages and modification...

... were heated, and temperatures of cavity filling were determined by the visual method. Twelve pegmatites were sampled, but extensive results were obtained from only three pegmatites. Beryl from inner zones of the Bob Ingersoll No. 1 and Highland Lode pegmatites gave lower temperatures than beryl from...

...Kenneth K. Landes Abstract The pegmatites described are the Etta, Hugo, Peerless, and Bob Ingersoll in Pennington County in western South Dakota. The deposits are pipe or dike-like intrusions into pre-Cambrian schist which forms the central part of the Black Hills uplift. Nearby, and genetically...

... the spodumene zone. In the Bob Ingersoll pegmatite, Black Hills, South Dakota, the overlap suggests a high degree of interzonal communication during crystallization. Alternatively, such overlaps in composition may result from extreme fractionation during late crystallization of one zone, overlapping with early...
