Dominican Amber
There are three main sites in the
Dominican Republic: La Cordillera Septentrional, in the north, Bayaguana and Sabana, in the east. In the northern area,
the amber-bearing unit is formed of clastic rocks, sandstone accumulated in a deltaic or even deep-water environment.
In the eastern area, the amber is found in a
sediment formation of organic-rich laminated sand, sandy clay, intercalated lignite as well as some solated beds of
gravel and calcarenite.
Both areas seem to have been
part of the same sedimentary basin, but later disrupted by movements along major faults. (Iturralde-Vincent and MacPhee, 1996).
According to Poinar, 2001, Dominican amber is from Oligocene to Miocene, up to 30 Mio years old.
The oldest, and hardest of this amber comes from the mountain region north
of Santiago area where we have our "Amber Ranch" from the mines at La Cumbre, La Toca, Palo Quemado, La Bucara, and Los Cacaos
mining sites in the Cordillera Septentrional not far from Santiago.
There is
also amber in the (south-eastern Bayaguana/Sabana area. It is less expensive, but softer,
sometimes brittle and suffers oxidation afer being taken from the mines.
And there is also copal found with only an age of 15-17 million years.
Since the amber in these mountains is tightly imbedded in a lignite layer of sandstone, holes are dug into the
sides of the cliffs.
The miners accomplish their work only with the help of primitive, simple tools and risk their
lives daily.
