تهیه نقشه زمین‌شناسی یکپارچه حوضه تهران از سوی سازمان زمین شناسی

مدیرکل دفتر زمین‌شناسی منطقه‌ زمین‌شناسی و اکتشافات‌معدنی کشور از مراحل پایانی پروژه تهیه نقشه یکپارچه استان تهران با مقیاس یک‌پنجاه‌هزارم خبر داد.

به گزارش ایسنا، به نقل از روابط‌عمومی سازمان زمین‌شناسی و اکتشافات‌معدنی کشور، رضا سلامتی ناظر پروژه تهیه نقشه یکپارچه استان تهران، با بیان این‌که این نقشه با مشاوره علمی دکتر حمید نظری معاون پژوهشکده علوم زمین در حال تکمیل است، افزود: برای تهیه این نقشه بیش از ۷۰ روز ماموریت صحرایی انجام شد و از واحدهای سنگی و رسوبات عهد حاضر جهت آزمایش‌های فسیل‌شناسی، سنگ‌شناسی، رسوب‌شناسی و کانی‌شناسی نمونه‌برداری‌های لازم صورت گرفته است.

وی با بیان اینکه پروژه تهیه نقشه یکپارچه استان تهران با مقیاس یک‌پنجاه‌هزارم مراحل پایانی خود را طی می‌کند اظهار کرد: در اوایل سال ۱۳۹۸ در مدیریت زمین‌شناسی منطقه‌ای با هدف ارائه اطلاعات دقیق‌تر، جدیدتر و پیاده‌سازی داده‌های تولید شده از مقالات معتبر بخصوص در زمینه لرزه‌زمین ساخت این پروژه آغاز شد و اکنون در مرحله پایانی تولید است.

سلامتی خاطرنشان کرد: متاسفانه با گسترش بی‌رویه شهر، حوضه آبریز طبیعی کوهپایه تهران، دست‌خوش تغییرات برگشت ناپذیر شده که بررسی‌های میدانی را با مشکلات بسیاری مواجه کرده که بر همین اساس علاوه بر برداشت داده‌های سطحی، از داده‌های زیرسطحی چاه‌ها، گودبرداری‌ها و ترانشه‌های راه‌ها و جاده‌ها استفاده شده است.

مدیرکل دفتر زمین‌شناسی منطقه‌ای سازمان زمین‌شناسی و اکتشافات‌معدنی کشور درباره مهم‌ترین ویژگی‌های پروژه تهیه نقشه یکپارچه استان تهران گفت: تطبیق داده‌های سن‌سنجی مطلق موجود و تعیین سن مجدد نهشته‌های آبرفتی تهران مهم‌ترین ویژگی‌ این پروژه است و براساس مطالعات انجام شده تغییر قابل ملاحظه‌ای در جایگاه ژئوکرونولوژی واحدهای آبرفتی ایجاد شده است.
