History

The region of Tarom is historically divided into two parts: Upper Tarom and Lower Tarom.[6] Medieval Arabic geographers usually wrote the name as aṭ-Ṭārumayn, or "the two Taroms", reflecting this division.[6] The mountainous Upper Tarom was historically counted as part of Daylam.[6] The name "Tarom" was applied to a right-bank tributary of the Sefid Rud, and the region of Tarom comprised the river and its own tributaries.[6]

An important location in Tarom was the castle and town of Semiran, which lay in Lower Tarom on the main highway leading to Sarab.[6] The castle crowned a rocky mount above the lower town and had triple walls.[6] Ibn Muhalhal visited here c. 943 and wrote that it was one of the main strongholds of the Daylamite kings and had about 2,850 houses.[6] The Buyid amir Fakhr al-Dawla captured Semiran in 989 from the Vahsudan dynasty.[6] Al-Muqaddasi wrote about the same time that the fortress of Semiran had "lions of gold, and the sun and the moon" on its walls; the town's houses were built from mud brick.[6] He counted Semiran as part of the Salārvand district.[6] Nasir-i Khusraw visited Semiran in 1046 during his pilgrimage to Mecca; he described it as the capital of Tarom.[6] Its fortress, he wrote, was garrisoned by a thousand men and had an underground conduit to supply water.[6] By the time Yaqut al-Hamawi visited Semiran in the early 1200s, the castle had been slighted by the Nizaris, although the ruins were still impressive enough that Yaqut called it "a mother of castles".[6]

Another fortress that Yaqut mentioned was Qilāt, located in the mountains on the Daylam frontier.[6] It was located atop a mountain and had belonged to the Nizaris of Alamut.[6] Below it was a town with "excellent" markets; there was also a masonry bridge with many arches crossing the stream.[6]

In the Nuzhat al-Qulub

The 14th-century author Hamdallah Mustawfi gave a detailed description of the two Taroms in his Nuzhat al-Qulub.[7] He described the two regions as fertile for agriculture – they supplied the city of Soltaniyeh with most of its fruit, he wrote – and populated mostly by Sunnis of the Shafi'i madhhab.[7] He wrote that a town called Firuzabad, which was in Lower Tarom, had formerly been the capital of the region, but by his lifetime Firuzabad had become "a complete ruin".[7] A place called Andar, which was in Upper Tarom, had replaced it as Tarom's capital.[7]

Mustawfi described the two Taroms as being divided into five districts.[7] The first consisted of the dependencies of Qal'ah Tāj ("the crown castle"), which was in Upper Tarom.[7] He said this district included about 100 villages; the most important were Jazlā, Shūrzad, Darām, Ḥayāt, Qalāt, Razīd, and Shīd.[7] The second district was based around the castle of Semiran, in Lower Tarom.[7] This district had about 50 villages, with the most important being Alūn, Khawarnaq, Sharzūrlard, and Kalach.[7] The third district was based around the castle of Firdaws, also in Lower Tarom; this district comprised about 20 villages, with the most important being Sarvān.[7] The fourth district was based around, instead of a castle, two large villages: Nisbār and Barīdūn.[7] It consisted of 8 hamlets that were dependencies of the two main villages.[7] Mustawfi did not specified whether this district belonged to Upper or Lower Tarom.[7] The fifth and final district was Lower Dizābād; Mustawfi said nothing about this district's affiliation either.[7] In any case, it had 25 villages; the most important were Gulhār, Gulchīn, and Balhal.[7] The combined revenue of these five districts, according to Mustawfi, was 64,000 dinars.[7]

Geology

Tarom is part of the Tarom-Hashtjin Metallogenic Province, which is one of the most important epithermal regions in Iran.[8]: 1  Lead, zinc, copper, iron, and manganese are prevalent.[9]: 271  Compared to the Hashtjin part, copper and iron are more widespread in Tarom.[9]: 271  The average copper content of plutonic bodies ranges from 220 to 260 ppm.[9]: 271  Lead, zinc, and silver content are 600, 800, and 8 ppm respectively.[9]: 271  Gold deposits are found mixed in with some copper deposits, such as at Khalifeloo, Abbasabad, and Chargar.[9]: 271  There are also gold deposits at Asadi and Ghez Ghal'e.[9]: 271  Tarom also has relatively more alunite deposits than Hashtjin, including ones at Yuzbash Chay, Kamar Rud, Nasr Abad, Sirdan, Zajkan, and Zajkandi.[9]: 271  There are also minor tungsten deposits, such as at Kuhian.[9]: 271  Sericitization is less widespread in Tarom than in Hashtjin, and "greisen-type metasomatism" has not been reported in Tarom.[9]: 271
