Geological and exploration studies
 
Geological and exploration studies
   This province has a long history of mining testified by various slag heaps of traditional smeltries.
   Systematic studies for geological and exploration studies have been started in 1973 in the framework of east Iran project. Most of mineral resource potentials are discovered during the course of preparation of 1:100,000 and 1:250,000 maps.
  
   4-1- Geological studies
   Geological mapping projects are carried out in two different scales as follows:
  
   A-1:250,000 geological mapping.
   The whole are of this province is covered by 16 sheet of 1:250,000
   quadrangles. All geological maps of this scale have been prepared and published with the exception of those sheets which are below 26 (latitude). The areas below 26 latitude are covered directly by 1:100,000 maps and their compilation to produce map of 1:250,0000 seemed to be unnecessary.
  
   B-1:100,000 geological mapping
   The most mineral resource promising areas of the province are covered by 1:100,000 geological maps. Desertic areas and plains are excluded by this type of mapping. These 1:100,000 maps and relevant reports have been published.
  
   C- Thematic geological studies.
   In addition to all published 1:250, 000 and 1:100,000 maps same thematic maps have been prepared.
  
   Some major important maps of these types are listed as follows:
  
   - Structural and geological map of hard rocks
   - Structural and geological map of hard rocks
   - Metallogenic map of north Zahedan.
   -4- exploration studies
   A major part of exploration studies is devoted to geochemical prospecting which are either regional or semi- detailed, detailed one. Some thematic studies are also carried out.
  
   A-Regional exploration
   Regional explorations are followed by using hammer prospection, stream
   sampling and ground radiometric methods. More over, following studies can be pointed out:
  
   - Metallogenical modelling of Sistan-va-Baluchistan province (1998) by compilation, completion and correction of existing data for delineation of target areas.
   - Exploration studies in a 30,000 km2 area by Zarcan Company of Canada.
  
   B- Thematic studies
   In addition to all aforementioned exploration efforts, 20 projects of exploration have been carried out using national and provincial funds.
  
   Many metallic and non metallic deposits are discovered in the course of execution of these projects. According to the report of Industries and Mines organization of this province 20 million tons of copper and 100,000 tons of chromite have been proved in this province Moreover magnesite, talc, huntite, silica pozzolan, marble and limestone in considerable amounts are reported.
  
   Followings are the list of projects carried out by industries and mines organization of this province.

   - Lar copper deposit
   - Feasibility study of copper ore beneficiation in Sistan-va-Baluchistan province.
   - Polymetallic mineralization in Asagi, Janja, Siasteragi.
   - Ore dressing plant installation for garnet, andalusite, feldspar, silica and Kaolin.
  
   C: Geophysical prospections
   Geophysical prospections are either regional or thematic. They are mainly directed toward the exploration of copper, asbestos, water and polymetallic deposits.

   3- Marine geology research
   Marine geology researches have been developed in Sistan-va-Baluchistan province in order to explore the mineral resources of coastal sands, construction of marine structures (military or development). More than one thousand kilometer of Oman beach belongs to Sistan-va- Baluchistan province. Therefore a project for marine geological studies has been started. Material and equipment needed for this project is partly furnished and training of staff for running this project is progressing.
   Geological reconnaissance has al ready been started and is under serious progression.
