Location of the deposit
This target is located in Gjegjan Commune – Pukw (Prroi i Shutenws) having these coordinates
Y = 4415100 Y= 4415600
X= 4645700 X= 4646100
His located south east of map sheet K – 34 – 76 – B – b
Danita’s contain only a few amounts of olivine, very little pyroxene and basic plague clause
Danita’s are rich in orthopyroxene, less serpentines and rarely are encorintered seppertiniza plagioclase Dunites
Hartzburgites are periodicities where pyroxene belongs to rhombic type (institute or bronzed) their chemical composition varies as follows: SiO2 = 37.1%, TiO2 = - ,
Al2O3 =0.89%, Fe2O3 = 1.46 %, FeO = 6.57 %, MnO = 0.12 %, MgO = 45.8 %, Cao = 0.32%, G2O3 = = 0.5 %, H2O + = 6.7 %, H2O- = 0.43 %
So that 90 % of rock is dominated by SiC = 37.1%, MgO2 = 45.8 %, and FeO = 6.57 %
Chemical composition of hartzburgites : SiO2 = 44.05 %,TiO2 = 0.1 % ,Al2O3 = 2.3 %,Fe2O3 = 0.83 %, FeO = 7.97,MgO = 41.35 %,CaO =2.2%,MnO = 0.12 %,G2O3 = 0.47 %,NiO = 0.31 &%,H2O = 0.87 %,Na2O = 0.007%,K2O = 0.003%
3.1. B Physical properties
- Hardness varies from 8 to 10.6
- Texture of these rocks is presented as
- In general their structure is massive, rarely is encountered layered structure
- Fascination as one of most important features, is stronger developed in surface,
Especially primary and secondary ones
-
Specific weight varies , from 2.728 to 2.95 gr/cm 3
-
Volumetric weight varies from 2.73 to 2.749 gr/cm 3
-
Humidity = 0.02 – 0.03 %
-
Natural absorption = 0.05 – 0.07 %
-
Porosity = 3 – 6.4 %
3.1. C – Mechanical properties
These indices result on the tolerable average
For example ( resistively in mono axial pressure ) = 560 – 640 (minimal ) up to 900 – 1100 kg / cm 2 , Rpr ( receptivity in section ) = 110 – 120 ( minimum ) up to 192 – 206 (maximum ) , Rt = 77 – 90 (minimum ) and 114 – 136 kg / cm 2 (maximum )
Estimated reserves in this target at the road level and up wards are some millions of m3 blocks
