Minerals
of Romania, Maramures County by Dan Mira
Maramures
(pronounced Maramuresh) is a Romanian county in northern
Transilvania, near the border with the modern Ukraine,
with a rich mining history. The first records and
archeological finds prove mining activities existed
in this region before Dacia (the country name before
the Roman conquest) was conquered by the Romans. A
lot of gold and silver artifacts showing the same
characteristics as the ones discovered locally were
discovered in other parts of Dacia, proving the quality
of the artifacts crafted locally was known and appreciated
in a wide area. Gold, silver, lead and zinc were commonly
extracted from the area. Manganese and barium were
also mentioned since the 1300s. High quality specimens
from the area filled collections and European museums
since late 19th century, however, the two world wars
and the following 50 years of communist regime kept
the specimens outside of the reach of collectors (especially
in US). The mines that are most familiar to collectors
are located in relatively small area around Baia Mare
(the Maramures county seat): Cavnic, Baia Sprie, Baiut,
Herja and Rosia Poieni. Most sought after specimens
include rhodochrosite, barite, black-and-white calcite
spheres and stibnite.

Dans talk will describe the geology, history,
minerals and the culture of this mining area. In addition,
Dan participated in the 3rd Cavnic Gem and Mineral Show
in 2025, which included a field trip to two local (closed)
mines. Dan will also be talking about specimens that
developed in a spherical shape (spherulites) that are
so abundant in the area. Dans personal collection
of minerals from Maramures will be displayed, including
new additions from this years trip to Cavnic and
a few specimens self-collected during the field trip
into local mines.

Dan's
Bio
Dan Mira is a Civil Engineer and passionate rockhound.
Born in Romania, Dan developed his interest in minerals
from his childhood and spent countless hours inside the
Bucharests National Geological Museum. He started
collecting mineral specimens only after moving to Denver
a few years ago. Despite the distance from Romania, he
kept permanent interest in Romanias minerals and
geology, and continuous connection with the Romanian rockhounding
community. |
