  • رصدت دراسة دولية تمزقين في صفيحة تكتونية ضخمة تغوص داخل الوشاح الأرضي تحت جنوب شرق إيران.
  • كشفت الدراسة عن مرحلتين لانغلاق محيط قديم وتغير سلوك الصفائح عند اقتراب القارات من بعضها.
  • أظهرت تقنية التصوير المقطعي الزلزالي اختلافاً في أعماق غوص الصفيحة المحيطية والقارة في منطقتي مكران وزاغروس.
  • تساعد هذه النتائج في فهم آليات تشكل القشرة الأرضية وتأثيرها على النشاط البركاني وتوزيع الضغوط.

اكتشفت دراسة دولية أدلة على ظاهرة جيولوجية غير مألوفة تحدث تحت جنوب شرق إيران، إذ رصدت تمزقين في صفيحة تكتونية ضخمة تغوص داخل الوشاح الأرضي في أعماق الأرض.
