چکیده

کانسار مس سرچشمه و سایر اندیس های مس پیرامون آن در کمربند دهج- ساردوئیه ( استان کرمان) قرار گرفته اند. گسلها گاه با ایجاد شرایط مناسب سینماتیکی و مکانی می توانند الگوی تشکیل رخ‌داد های مس را کنترل کنند. در راستای بررسی صحت این فرضیه، با استفاده از روشهای سنجش از دور، خطواره ها، استخراج و سپس با مشاهدات صحرایی، گسلهای اصلی و فرعی مشخص شدند. بررسیهای ساختاری در قالب تهیه نمودار گل سرخی و محاسبه محور فشارش انجام شد. با استفاده از قابلیتهای GIS، اقدام به تهیه نقشه هم‌شکستگی و فاصله داری رخ‌دادهای مس از گسلها شد و لایه موقعیت رخ‌دادهای مس بر روی سایر لایه های خروجی منطبق شد. نتایج بررسی نقشه های خروجی نشان می دهد گسلهای اصلی دخالت مستقیمی در کنترل محل رخ‌دادهای پورفیری و رگه ای نداشته و رده های دوم این پهنه های گسلش، موقعیت رخ‌دادها را کنترل کرده اند. همچنین مشخص شد که محل رخ‌دادهای مس آغشتگی ارتباط نزدیکتری با گسلها داشته و بیشتر رخ‌دادها نزدیک به گسل رفسنجان قرار دارند.
