2008 Micromounters of New England
Annual Mini-Symposium
Saturday, May 17, 2008
at the Elk's Lodge in Hudson MA
Guest speaker will be Bill Henderson presenting talks on:
Microminerals of Italy
taly has experienced an extremely varied geological history, resulting in a great number of rock types and parageneses. These in turn have lead to an amazing number of mineral species. In fact, it would be hard to find any country of a similar size with so many. Further, a substantial fraction of these species occur in truly beautiful micro crystals. This talk will show these species arranged by their chemistry and paragenesis.

Microminerals of the Palabora Mine, South Africa
The Palabora Mine, located near the town of Phalaborwa (yes, the spellings are correct) is working in a carbonatite rock. Carbonatites are extremely rare, igneous rocks composed mostly of calcite. Several elments found only in trace amounts in granites, etc., are concentrated in carbonatites, and these crystallize to form rare minerals. In most cases, such minerals are massive or, more properly, anhedral. Only rarely are the minerals at Palabora or elsewhere found in open cavities where thay form nice specimens. Examples of such, obtained by exchange with the mine superintendent no less, are shown in this talk. |
Microminerals of Etruscan Slags
In pre-Roman days, the Etruscans mined ores on the island of Elba, where Napoleon was exiled, and carried them by sea by the thousands of tons per year to the region of Populonia on the Italian mainland. There, they were smelted, but only poorly, leaving much metal behind in gas cavities in the slags. This metal has reacted over time with sea water to form a variety of attractive microminerals such as fiedlerite, barstowite, shattuckite, spangolite and very rare species such as elyite and gerhardtite. This talk will cover and show 25 of the 44 slag species found at Populonia. |

The Micromounters
of New England was organized on November 8, 1966
for the purpose of promoting the study of minerals that require
a microscope. Read A
Brief History by Janet Cares. As the name implies, we
are unique, different from other mineral clubs, and try to
emphasize this difference. We try to keep dues and other expenses to a minimum in order that
everyone may participate. See Thoughts
on Micromounting by Pat Barker.
