چکیده: در راستای سیاست كلی دولت مبنی بر عدم وابستگی سیاسی؛اقتصادی ورهایی از سیاست تك محصولی و جهت رشد و شكوفایی صنایع و بر آورد نیاز اولیه آنها با توجه به وسعت صنایع و گسترش آن در سطح استان تهران و روند رو به رشد آن در سایر مناطق و نیز با نگرش به تنوع حوادث زمین شناسی و رسوبات آن در تهران مصمم شدیم قدمی هر چند كوتاه در این راستا برداشته و برآن شدیم كه در سطح استان تهران پتانسیل یابی مواد معدنی را بررسی نماییم.ذكر این نكته لازم است كه استان تهران با توجه به موقعیت آن از لحاظ مركزیت كشور ؛ وجود مراكز دانشگاهی وسازمان زمین شناسی و حضور متخصصین زمین شناسی خارجی در سالهای قبل تا حدودی از لحاظ اطلاعات زمین شناسی واطلاعات اولیه در بعضی مناطق غنی می باشد و گزارشهایی نیز در مراكز یاد شده وجود دارد ولی از لحاظ زمین شناسی اقتصادی و بعد شناخت مواد معدنی و با توجه به اولویت ها فعالانه در این راستا قدمی برداشته نشده است0با توجه به اینكه استان تهران یك منطقه نسبتا وسیع و با پراكندگی روستاها وجمعیت ها است و همچنین بدلیل وجود سلسله جبال مرتفع البرز در شمال این منطقه كه باعث صعب العبور شدن خیلی از نقاط این استان شده و بعلت تنوع رسوبات از لحاظ زمین شناسی و حوادث تكتونیكی اتفاق افتاده؛ مطالعات بصورت مناطق مجزاء در نظر گرفته میشود كه بتوانیم نیروی بیشتری در یك منطقه اعمال نمائیم و به همین منظور از مساحت استان كه در حدود 30000 كیلومتر مربع می باشد قسمت غرب استان یعنی بخشهاو روستاهای كرج-اشتهارد- ساوجبلاغ- هشتگرد با مساحتی كه در حدود پنج هزار كیلومترمربع است مورد پی جویی قرار گرفته شده است كه ره آورد آن بطور خلاصه بشرح زیر میباشد: ...
