Data title : 4-9-2 mineralization

Belt Malayer – Isfahan metallogeny, mineralization is seen in the following:
- Regional metallogeny Shams Abad - Abad system with lead and zinc mineralization, gold, silver, tungsten, tin,

- The lead-zinc and silver mineralization with metallogeny blacksmiths, iron and manganese,
- The Mouteh auriferous mineralization.

Some parts of the mineralization in Figure 4-12.

 
Lead-zinc mineralization

Based on this, more than 120 deposits of lead and zinc Mineral Reserves are reported in the final set of known (and mining residues) is more than 60 million tons. Among these, half of the area and the other half in the Khomein, reconciliation, Malayer, Shams Abad is placed. Possible to store the belt, is more than the amount mentioned. Signs of mineralization and mineral deposits of lead and zinc, are often bound and stratigraphy of mainly calcareous rocks, calcareous - dolomite - Chile and the Cretaceous sandstone are limited, however, few signs of mineral deposits and lead-zinc , Think of the host rocks older than Cretaceous.
The stratiform lead-zinc mineralization, vein, and the lens is seen.

In the western part of the ligament, stereotypes, building with the deposits, alteration of silica, calcite and dolomite are in the clear. While the eastern part of the area is in Anjireh - Tyran, so that no such alteration.

The origin of these deposits has different ideas, all of which are divided into two categories.
Mississippi Valley type that is subject is by further research. Given this fact, believing the whole of this belt-driven fan but have studied the Mississippi Valley type, or any part of the study have particular deposit. It seems that both of these motives, the role of lead and zinc mineralization have been, but more significant are the Brigade and more are in the western part of the outcrop belt, but the Mississippi Valley-type, more eastern part (of area) is considered.

 
Gold Mineralization

Gold mineralization in this belt, can be seen in two horizons:

1 - the Precambrian rocks - Paleozoic, most of the fault zone is like gold and Azna,
2 - along with some like the Mesozoic intrusive granite mass threshold.


Iron and manganese mineralization

Mineralization of iron and iron - manganese in Precambrian rocks - Paleozoic and Cretaceous rocks can be seen. Iron mineralization in Precambrian rocks - Paleozoic non-economic, but in the Cretaceous rocks, the mineralization is economic.


Manganese mineralization in the Cretaceous rocks in many areas has been seen sporadically.


Tin and tungsten mineralization

Hornfelsic rocks and associated granites and metamorphic rocks, sometimes Lower Cretaceous, tin and tungsten mineralization (such as tungsten deposits Arak Nezam Abad) and tin in the area south of the threshold (ten Hussein hole Homa) and East Aligudarz (range and Soil Col-Abad) is seen.


Copper mineralization

Malayer Metallogeny belt - Esfahan, in places above the Paleozoic basement - Lower Triassic is observed, works of copper mineralization is seen so far specific studies have been done on them.

Formation of nonmetallic deposits

In this group of deposits, talc, graphite, barite, and Stones, are important. Generally, the belt Metallogeny except Pb mineralization wide area Metallogeny and other mining areas are seen in the geological description was referred to.
