Tarikh (al-Tabari) 17
Creation of the heavens and the earth
ذِكْرُ الْمَعَادِنِ قَدْ أَحْصَى بَعْضُ الْقُدَمَاءِ الْمَعَادِنَ الْمَعْرُوفَةَ كَالْجِصِّ وَالنَّوْرَةِ فَوَجَدُوهَا سَبْعَمِائَةِ مَعْدِنٍ . قَالُوا: وَلَا يَنْعَقِدُ الْمِلْحُ إِلَّا فِي السَّبْخَةِ، وَالْجِصُّ [إِلَّا] فِي الرَّمْلِ وَالْحَصَى.
