Explanation

The Chirchiq-Ohangaron district lies in the north-east of Uzbekistan between the Syrdarya and the Western Tien Shan. In the north-west it borders Kazakhstan and in the east Kyrgyzstan; the Kurama range separates it from the Fergana Valley and its south-western boundary follows the Syrdarya. The district includes part of the Western Tien Shan, the Chirchiq and Ohangaron valleys and the Dalverzin desert. The surface falls from the north-east towards the Syrdarya. The mountains (Ugam, Pskem, Chatkal, Kurama, Karzhantau) were folded and raised in the Paleozoic and later worn down; new tectonic movements still continue, so earthquakes occur. The highest peaks are Beshtor (Pskem) 4299 m, Sayram (Ugam) 4236 m, Baboiob (Kurama) 3769 m and Greater Chimgan 3309 m. A road and railway run to the Fergana Valley through the Kamchik pass (2267 m). The district is rich in copper, gold, tungsten and lead ores, alunite (aluminium raw material) and kaolin (porcelain raw material).

Worked examples
The route from Tashkent to Fergana crosses the Kurama range, so the Kamchik pass and its tunnels are an important transport corridor.
The kaolin deposits of the Ohangaron valley supply raw material for making porcelain and ceramic ware.
Class activity

“Hand of ranges”: draw your hand as a map, make the Ugam, Pskem and Chatkal ranges the fingers and write the peak heights.
