39 29 The groundmass of the Quartz-Eye Porphyry is aphanitic with an aplitic texture. The general appearance is "dusty" due to the presence of finegrained sericite and clay. The only recognizable primary phase in the groundmass is quartz. Zircon was noted but is uncommon. X-ray diffraction scans indicate that sericite and clays of the kaolin group are indeed present. Orthoclase also observed on the x-ray scan may indicate it is present as a phenocryst phase or in the groundmass, or both. Finally, the x-ray scan indicated the presence of dolomite even though it was not noted petrographically. Breccias Distribution Three types of breccias are present in the Black Gulch area: 1) intrusive breccias, 2) contact breccias and, 3) fault breccias. Two bodies of intrusive breccia were mapped, both of which passively intruded shales and limestone of the Benton-Niobrara undifferentiated (Kbn). One body located on the east end of Haggis Hump (Plate I), is termed the Haggis Hump Breccia (Thhb). The body is a breccia dike approximately 2 meters in width and has extremely sharp contacts with the surrounding rocks (fig. 15). The Kbn to the north was not disturbed by the intrusion of the breccia. However, minor calcite veining-in the Kbn may be related to the emplacement of the breccia body, since the Thhb contains disseminated calcite in the matrix.
