there are various ways in exploration. Each method is done with a special technology that will be referred to the following:
This type of exploration is done without any special technology and as following forms:
(A) Accidental explorations
Mineral exploration is not a science. Many good Ore deposits are found by researchers and or mineralogist. Perhaps no country such as Iran can be useful for simple exploration.
Beauty and special physical properties of minerals make them different from other types and it will be very useful in simple and accidental exploration so far. Of course mineral beauties are mistakes, that’s why pyrite is named fools’ gold.
(B) Intensive Exploration
Intensive Exploration is used for mining and abandons old mines in Iran. Intensive mines have following properties.
- It is done in mining and saving with western science and all of mining and saving is done by science and all of mining and saving is done by Iranian people.
- Explosive materials and machines which have mobile force were not used.
- Mainly, this type of mining refers to Abbas Mirza Era.
This type of exploration is done by mineralogists and geologists. In this method, some various regions are carried out by scientific and award selection by oriented following. In past years, this method has good results, such as generation of phosphate horizons in many points of Iran, refractory horizons in central Iran and Alborz and Sr-bearing horizons in Zagros and … and simple exploration because it has less exploration cost and it depends on awareness, intelligence degree, geologists skills and especially in mining date in a nation and we can say has the first place and we know less saltiness which is as some as that (Ref, Chapter 1).
Mineral Reservoirs are formed in a special geological environment and or in other words as some legal mineral reservoirs. Generation of a special reservoir has some evidences.
Which are compared to other regions. Geologists are discovered by study of various ore deposits and they have gained some information and in other points they seek them. Nowadays this exploration method is a base of or new exploration. Preparation of metallogeny maps does not need high technology but expertise and skilled human resource that our country is at the beginning of this way. Chapter 4 in this book is an initiation for writer.
Geochemical Exploration is based on these realities that nature is created in this way Khoy are ruined. In geometrical survey, oil and gas fields from oil gases ascending are such as ethane and ethane too. Geochemical surveys are follow seriously by progressed and big mineral companies and they have been follow with good results.
In our country, this machine is present in many governmental organization but they do not use then as optimized. Although experts are susceptible in GSI and mineral companies but there are some geochemical exploration in country is measurement of Au, Ag, As and REE and Pt Group in outside of country from expertise and much enough precision.
In Geophysical Exploration of ore deposits, physical characteristics of rocks are such as magnetic field intensity, electrical conductance and radiation and velocity of seismic waves are measured. Although most measurement methods have reflected general nature of rocks but some of them can be obvious in reality as a evidence for mentioned mineral or element.
Major geophysical explorations in metallic material exploration are radiation method, electrical, magnetism, gravimetry and … and geophysical exploration in suitable positions which is done in ground surface and it characterize presence of mineral bodies in a depth of 100 and over. We can use this type of measurement among younger sediments which are covered by mineralized rocks for study of underground study. This ability has Vast usage in Vast areas of Canada and Northern Europe than gravel and sand as glacial is big part of host rock with mineral material.
Common methods in geophysical exploration in Iran are mentioned in table No 7-7. It is necessary that new technologies are 3D and 4D geophysical in oil exploration has much use in the world and it is important role in decrease of explorative costs. These methods are using in petroleum Co..
