Minerals inAfghanistan

There are at least 21 factories producing marble in Afghanistan,but the total output is not known. The marble is exported asrough hewn blocks to Pakistan where it is processed and thentransported back to Afghanistan. This imported marbledominates the market as local producers are unable to competewith the low prices and high quality. The Afghanistan marbleindustry suffers from a lack of adequate equipment, has little

technical knowledge, and uses poor extraction methods thatoften significantly reduce the value of the marble. Extraction is byblasting using ‘black powder’, typically imported from Pakistan.This causes micro-fracturing throughout the entire quarry andresults in up to 50% of wastage at the quarrying stage. Furtherwastage occurs at the marble factory where blocks often break upduring the cutting and polishing stages of production.

The result is a relatively poor quality polished marble with acomparatively high unit cost of production.

There is a wide variety of marble in Afghanistan currentlyextracted from quarries in Badakhshan, Balkh, Bamyan,Helmand, Herat, Kabul, Kandahar, Logar, Faryab, Wardak,Nangarhar, Paktia, Parwan and Samangan provinces. Marblesdeveloped in rocks of Proterozoic age are considered to be thehighest quality for use as dimension stone. Marble depositsinclude the following:

● Kabul Province. Proterozoic marble is quarried in Ghazak,Hazare Baghal, Kariz-Amir, Pul-e-Charkhy, Qalamkar, andTara Kheel. The Proterozoic Kariz-Amir marble occursapproximately 40 km north of Kabul and consists ofgranular white, rarely grey-yellow marble. The Ghazakmarble (known as ‘Ghazak Black’) is a popular fine-grained, black marble that occurs 32 km east of Kabul.

● Logar Province. Proterozoic marble is quarried inAwbazak, Dehnow and Mohammad Agha. Awbazakmarble is bioclastic and brown in colour; Dehnow marbleis brecciated and brown in colour; Mohammad Aghamarble is black and white in colour.

● Wardak Province. The Proterozoic Maydan marble occursnear Maydan Shar and consists of grey and dark greymarble ‘beds’ up to 450 m thick, interbedded with schist.The ‘Maydan Marble Mines’ are well known, with five

working areas in a 10–12 km outcrop that has beenworked for 40 years.

● Badakhshan Province. The Silurian-Devonian Bini-Kamamarble consists of medium and coarsely crystalline marble;the resource is estimated as 1300 million tonnes.

● Herat Province. The Proterozoic Chesht-i-Sharif marbleoccurs 120 km east of Herat city and consists of a finelycrystalline marble ranging in colour from pure white to asubtle light green.

● Nangarhar Province. The Proterozoic Khogiani marbleoccurs 35 km south-west of Jalalabad and consists of awhite marble known as ‘Afghan White’.

Onyx marble. Onyx is a banded variety of chalcedony, acryptocrystalline form of quartz. Onyx is highly valued as a highquality marble and the colour of its bands range from white toalmost every other colour. Afghan onyx is quarried from severalprovinces including Bamyan, Helmand and Faryab, withcolours including shades of yellow, green or brown. Some ofthese may in fact be a variety of aragonite (calcium carbonate)called travertine, however the traditional name of onyx hasremained in place and is still used to this day.

The Chesht and Khogiani marbles are currently worked fordimension stone and have been favourably compared toCarrara marble, an Italian marble recognised to be one of thefinest in the world.
