Scanning electron micrograph of a large radiating cluster of dachiardite crystals deposited on hydrothermal quartz crystals. Yellowstone National Park, Wyoming. No date.
Summary
Figure caption: Scanning electron micrograph of a large radiating cluster of dachiardite crystals deposited on hydrothermal quartz crystals in a cavity at about 60 m in drill hole Y-3. Paragenetic sequence of quartz (upper left and lower right), blocky dachiardite crystals (extending from upper right to left centre), radiating fibrous mordenite crystals, and numerous clusters of tiny smectite crystals (after Bargar et al. 1981). No index card. Published as Figure 12 in Zeolites in Yellowstone National Park. The Mineralogical Record; 12: 29-38. Published as Figure 3-B in Dachiardite from Yellowstone National Park, Wyoming. Canadian Minerologist; 25: 475-483. Published as Figure 11 in Calcium zeolites in rhyolitic drill [...]
