English: A satellite picture of the Dasht-e Kavir desert in Iran.

The patterns you see are formed by different geological layers that have been eroded over thousands of years by wind and sometimes (but not often) rain.

The patterns are formed from either horizontal geological layers cut through by topographic changes, or geological formations (folds, domes, etc) in relatively flat terrain.

Most of the colours are due to chemical differences in the rocks, whilst the intense blue colours could be due to a range of materials, possibly salt deposits, possibly vegetation, depending on which area of the EM spectrum is represented by blue. I suspect (but don't know, the satellite bands to displayed colours are not mentioned) that the blue colours are salt deposits, but they could equally be other materials too. To be certain, knowledge of the bands to display colours is essential.

The black line running horizontally across the image is a sensor drop-out and the data for that line or lines has been irrevocably lost. The linear (but not straight) line running vertically down the middle left is a road.

USGS/NASA description: The Dasht-e Kevir, or Great Salt Desert, is the largest desert in Iran. It is primarily uninhabited wasteland, composed of mud and salt marshes covered with crusts of salt that protect the meager moisture from completely evaporating. This image was acquired by Landsat 7’s Enhanced Thematic Mapper plus (ETM+) sensor on October 24, 2000. This is a false-color composite image made using infrared, green, and red wavelengths. The image has also been sharpened using the sensor’s panchromatic band.
فارسی: تصویر ماهواره‌ای از دشت کویر ایران. اکثر رنگ‌های موجود در نگاره و تفاوت‌های شیدهای مختلف، به دلایل اختلاف‌های ترکیبات شیمیایی مواد تشکیل دهنده صخره‌ها و تپه‌ها است که در کنار یکدیگر جلوه‌گر شده‌اند. رنگ‌های تند آبی احتمالاً ناشی از رسوب نمک‌های باقی مانده از رستنی‌ها و گیاهان کویری است. البته این استنتاج بستگی مستقیم به طیف الکترومغناطیسی دارد که با رنگ آبی نمایش داده شده‌است.
