Mineral Specimens with Minium
- 5 specimens selected
6.0 x 4.8 x 4.5 cm. Minium is a RARE secondary alteration product of lead. This brick-red specimen is SOLID minium, either as microcrystals or in massive form. Sparkly lead microcrystals RICHLY cover one face and are scattered on other faces and in vugs on this rare mineral from a VERY UNCOMMON Utah locality - the iron mines near Cedar City. The iron mines operated from 1851 through the 1980s. Ex. Charles Hansen Collection, a noted California collector. Hefty for the size (lead, of course) at 303 grams or 10.7 ounces.
7.0 x 4.7 x 3.8 cm. Minium is a RARE secondary alteration product of lead. This brick-red specimen is SOLID minium, either as microcrystals or in massive form. A very well-placed, 7 mm cluster of lead microcrystals dominates the front of the scupltural matrix and lead microcrystals are scattered on other faces and in vugs on this rare mineral from a VERY UNCOMMON Utah locality - the iron mines near Cedar City. The iron mines operated from 1851 through the 1980s. Ex. Charles Hansen Collection, a noted California collector. Hefty for the size (lead, of course) at 282 grams or 9.9 ounces.
6.3 x 5.8 x 4.2 cm. Minium is a rare secondary alteration product of lead. This yellowish-green to brick-red specimen is solid minium, either as microcrystals or in massive form. Lead microcrystals, as discrete crystals or as clusters or masses are richly scattered on the 3-dimensional mounded matrix from a very uncommon Utah locality - the iron mines near Cedar City. The largest lead crystal is 2 mm. Ex. Charles Hansen Collection. Hefty for the size (lead, of course) at 427 grams.
6.5 x 5.0 x 4.0 cm. Minium is a rare secondary alteration product of lead. This yellowish-green to orangish to brick-red specimen is solid minium, either as microcrystals or in massive form. Lead microcrystals, as discrete crystals or as clusters or masses are richly scattered on the 3-dimensional mounded matrix on this rare mineral from a very uncommon Utah locality - the iron mines near Cedar City. The largest lead crystal is 5 mm. The iron mines operated from 1851 through the 1980s. Ex Charles Hansen Collection. Hefty for the size (lead, of course) at 450 grams or 15.8 ounces.
4.8 x 3.8 x 3.4 cm. Intense red microcrystals or druse coating matrix, of this lead oxide species. The matrix seems to be cerussite altering to galena or anglesite, and is surprisingly hefty. Ex. Bill Pinch Collection.
