چکیده

منطقه ارزوئیه در مرز دو استان کرمان و هرمزگان قرار دارد. در این منطقه اکتشافات رسوبات آبراهه ای در مقیاس 1:100000 انجام شد. مهمترین عنصر اکتشافی در این منطقه کروم است که در اصل باید با پریدوتیت ها و دیگر سنگ های اولترابازیک همراه باشد؛ ولی در منطقه مقادیر بالای کروم با سازندهای تخریبی همخوانی دارد. برای تعیین زون های آنومالی فلزی و حذف آنومالی های کاذب می‌توان از چند روش استفاده کرد که در این پژوهش از روش شاخص آماری AHP و سیستم اطلاعات جغرافیایی استفاده شد. در این راستا، سه معیار لیتولوژی، ژئوشیمی عنصری و زمین‌ساخت در نظرگرفته و سپس با استفاده از این مدل، عوامل مربوطه ارزیابی و تعیین وزن شد. در پایان برای تهیه نقشه نهایی، لایه های اطلاعاتی این عوامل در محیط GIS تهیه و تلفیق شد. نتایج حاصل از بررسی نقشه آنومالی نشان داد که این روش باعث حذف آنومالی های کاذب در این منطقه می شود.
