Anhydrite (CaSO4) is the anhydrous form of gypsum and is used in the manufacture of cement, and can be a source of sulfate for sulfuric acid. The map shows the distribution of sites and map units in which anhydrite has been observed by the field teams. In most instances anhydrite was observed in thin broken bands within the soil profiles. Occasionally it was observed as a thicker layer of variable extent. || الأنهيدريت (CaSO4) هو الشكل اللامائي من الجبس، ويستخدم في صناعة الأسمنت، كما يمكن أن يكون مصدرًا للكبريتات في إنتاج حمض الكبريتيك.<\/SPAN><\/P>

تُظهر الخريطة توزيع المواقع والوحدات الخرائطية التي تم فيها رصد الأنهيدريت من قبل الفرق الميدانية.<\/SPAN><\/P>

في معظم الحالات، تم ملاحظة الأنهيدريت على شكل شرائط رقيقة ومكسورة داخل مقاطع التربة. وأحيانًا، وُجد على شكل طبقة أكثر سمكًا ذات امتداد متغير.<\/SPAN><\/P>
