Gold prospecting using Remote Sensing ‘A case study of Sudan’

<p>Gold has been extracted from northeast Africa for more than 5000 years, and this may be the first place where the metal was extracted. The Arabian-Nubian Shield (ANS) is an exposure of Precambrian crystalline rocks on the flanks of the Red Sea. The crystalline rocks are mostly Neoproterozoic in age. ANS includes the nations of Israel, Jordan. Egypt, Saudi Arabia, Sudan, Eritrea, Ethiopia, Yemen, and Somalia. Arabian Nubian Shield Consists of juvenile continental crest that formed between 900 550 Ma, when intra oceanic arc welded together along ophiolite decorated arc. Primary Au mineralization probably developed in association with the growth of intra oceanic arc and evolution of back arc. Multiple episodes of deformation have obscured the primary metallogenic setting, but at least some of the deposits preserve evidence that they originate as sea floor massive sulphide deposits.
