The Iasi county (number 17 in table 1)
have only 6 mineral substances but the big
economic necessities had obligated at more
exploitation intensity (85 quarries and open
pits) to Mehedinti county (number 18 in
table 1), where an same approximate number
of quarries and open pits (80) had exploited
21 mineral substances.
Another observation: usually, the counties
containing mountain (Hunedoara, Bihor,
Cluj, Maramures, Arad, Covasna, Suceava,
Brasov, Caras Severin, Harghita, Gorj, Salaj,
Alba, Prahova, Mehedinti, Arges, Buzau,
Dambovita, Sibiu, Satu Mare, Bistrita
Nasaud, Valcea, Timis) and plateau areas
(Tulcea, Constanta, Iasi) have the most
quarries and exploited mineral substances.
The counties containing only field areas
(Giurgiu, Dolj, Olt, Galati, Ilfov, Teleorman
Ialomita, Calarasi, Braila) had exploited few
mineral substances. Some counties can to
have satisfactory open pits becose they
exploit sand and gravel along the rivers.
4 SURFACE MINING ON SUBSTANCE
It exists a very big inequality of the
quarries and open pits on (solid) substances.
Five substances (sand and gravel, common
limestone, common clay, andesite and
sandstone) were extracted with very much
quarries and open pits number: 2072 (see the
figures 4).
Figure 4. Surface exploitations percents on
the first five exploited substances and
remainder substances (1=sand and gravel;
2=common limestone; 3=common clay;
4=andesite; 5=sandstone; 6=other 77
substances).
