این تحقیق با هدف تدوین استراتژی برای مدیریت زمین شناسی و اکتشافات معدنی منطقه جنوب خاوری با مرکزیت کرمان انجام گرفته است. این مدیریت امور اکتشاف مواد معدنی و تحقیقات مرتبط با علوم زمین در جنوب شرق کشور را بر عهده دارد. این مدیریت نیاز مبرمی به شناخت نقاط ضعف و قوت و نیز فرصت ها و تهدیدهای محیط فرا روی خود داشت تا با تدوین استراتژی های مناسب بتواند نقش و وظایف خود را به خوبی اجرا نماید. روش مورد...

In this work, the concentration gradient (CG) analysis of local-scale exploration for Porphyry-Cu deposits is applied in two zones using the G(Vz) index (CG(Zn*Pb)/CG(Cu*Mo)). The first zone is covered by a 1:2000 map of the Sungun and Astamal areas in NW Iran and the second one in the Inza area in British Columbia, Canada. The rock samples are taken from Sungun and Astamal and the soil samples...

Delineation of oxide and sulfide zones in mineral deposits, especially in gold deposits, is one of the most essential steps in an exploration project that has been traditionally carried out using the drilling results. Since in most mineral exploration projects there is a limited drilling dataset, application of geophysical data can reduce the error in delineation of the sulfide and oxide zones....

our civilization is based on metals, among other life supports. the existing ore deposits are becoming rapidly depleted by almost exponentially increasing demand and production and major new ore discoveries are needed. mineral exploration is supported by modern tools and scientific ideas, but geological characteristics of orebodies and their rock associations have still to be visualized.the tim...

GIS is considered an important technique as well as a prerequisite for cost effective mineral exploration and determination of high potential areas. The purpose of this research is to determine high potential iron zones for detailed exploration using index overlay GIS method. Index Overlay was used to combine the geology, topography (scale: 1:1,000), lineaments, remote sensing (ASTER and ETM+) ...
