Potansiyel Mineralizasyon Kuşaklarının Uzaktan Algılama Yöntemleri ile Saptanması, Gongola, Doğu Nijerya

Year 1990, Volume: 14 Issue: 1, 33 - 36, 15.05.1990

Abstract

Yeryüzündeki maden kuşakları genellikle uzunlamasına, eğrisel veya dairesel yer şekilleri ile ilgili olarak belirirler. Bunun nedeni, magma ayrışması sürecine bağlı olarak, minerallerin zengin olduğu eriyiklerin bu zayıf noktalardan yerin üst kabuğuna geçerek ya bu var olan çizgisel şekiller boyunca veya volkanitler şeklinde katılaşmasıdır. Bu şekiller önemli jeolojik anomalilerdir ve maden içerebildikleri için derinliğine araştırılmaları gerekir. LANDSAT verilerinden potansiyel maden bölgelerinin saptanması daha önceki deneyimlerle kanıtlanmıştır. Bunlara benzer olarak bir Nijerya LANDSAT fotoğrafında yapılan değerlendirme, Doğu Nijerya'nın Gongola eyaletindeki bazı yerlerin yüksek mineralizasyon potansiyeli olduğunu göstermektedir.

Remote Sensing Lineament Interpretation for Mineral Exploration in Gongola, East Nigeria

Year 1990, Volume: 14 Issue: 1, 33 - 36, 15.05.1990

Abstract

Most of the mineralization zones are related to linear and curvilinear features. This is due to the magma differentiation process where by the mineral rich fluids either solidify along existing lineaments (fractures) forming linear features, or intrude into the upper crust as igneous bodies forming curvilinear features. These linear features are conspicious and easily recognized on remotely sensed data which invites the attention to the anomalous geologic features for detailed investigation. Previous experiements to identify mineral target areas on LANDSAT imageries give encouraging results. Similarly, a Nigerian LANDSAT image interpretation indicates areas of high potential for mineralization in South Gongola State, Eastern Nigeria.
