The trade scenario in the Ottoman Empire
Between 1826 and until 1838 the Ottoman Empire, in response to the Industrial Revolution, to protect the internal market and to control/limit the export of commodities, restricted internal trade to local monopoly agents (Yed-i Vahid system) barring foreigners from domestic commerce. These agents purchased exclusive trading rights of specific or a group of commodities from the Ottoman administration (the Porte). Foreigners were limited to import-export activities. The 1838 Balta Liman Treaty of Commerce ended these monopolies and granted foreigners access to domestic trade, but remnants of the old system persisted, and foreign participation remained limited until the 1850s.

Chromite discovery in Turkey
In 1848 Prof. John Lawrence Smith, an American chemist and mineralogist temporary working (1846-1850) for the Ottoman administration, while conducting mineral exploration in Bursa province southeast of Constantinople at 57 miles distance, discovered the first chromite deposits in Turkey, near the village of Nallılar (currently in the Orhaneli district). Further discoveries took place later southern in the Harmancık district and then in the neighbouring province of Kütahya (Dağardı mine).

Geochronology

Mineralization age: Mesozoic : 230 Ma to 100.5 Ma

Important note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
