DERE SEDİMANI VERİLERİNE "FRAKTAL MODEL" VE "FAKTÖR ANALİZİ" UYGULANARAK CR MİNERALİZASYONUNUN TANIMLANMASI: KHOY 1:100.000 PAFTASI, KB İRAN

Fraktal yöntemler, sığ ve derin mineralizasyon zonlarının sınırlarının birbirinden daha hassas bir şekilde ayrılması açısından oldukça etkili yöntemler olarak kabul edilmektedir. Bu araştırmada, KB İran'da bulunan Khoy 1:100.000 ölçekli jeoloji haritası içinde, Cr, Co ve Ni gibi elementleri açısından umutlu olabilecek alanları saptamak amacıyla konsantrasyon-numara (C-N) ve konsantrasyon-alan (C-A) fractal yöntemler uygulanmıştır. Elementler üzerinde factor analizi uygulanmış olup her iki fractal yöntem, elementler ile ilişkili faktörler izole edilerek çalışılmıştır. Ekstrem anomalilerin güncel jeolojik konumları araştırılmış olup sonuçlar karşılaştırıldığında bunların çok yakın ilişki sundukları ve çakıştıkları gözlenmiştir. Sunulan model sonuçlarına bakıldığında, incelenen çoğu elementin, paftanın merkez ve GB kesimlerinde kaldıkları anlaşılmıştır. Litoloji açısından bakıldığında ise, bu alanlar serpantinitin harzburjit ve dünit gibi ultramafik kesimlerine karşılık gelmekte olup aynı zamanda Cr mineralizasyonu açısından yüksek olasılıklı alanları göstermektedir. Ulaşılan sonuçlar aynı zamanda faktör analizi ile doğrulanmıştır. Bu ise, bu elementlerin faktör akümülasyonunun her bir elementinki ile tam olarak aynı olduğu anlamına gelmektedir

DELINEATION OF THE CR MINERALIZATION BASED ON THE STREAM SEDIMENT DATA UTILIZING FRACTAL MODELING AND FACTOR ANALYSIS IN THE KHOY 1:100,000 SHEET, NW IRAN

Fractal methods are regarded as a highly efficient method for more accurate separation of boundaries between mineralized zone in shallow and deep studies. In this research, concentration-number (C-N) and concentration-area (C-A) fractal methods were used in order to identify promising areas of the elements like Cr, Co and Ni in the Khoy 1:100,000 geological mapping sheet, NW Iran. The factor analysis was performed on the elements, and factors, which were related to the elements, were isolated and studied by both fractal methods. The current geological locations of the extreme anomalies were investigated and the results showed a very close relationship and overlapping. The results of the presented models show that the most elements under study are located in the central and southwestern parts of the sheet. From the point of view of the lithology, these areas correspond to the serpentinite ultramafic units of harzburgite and dunite, and as a result, there is a high probability of Cr mineralization. The achieved results are confirmed by factor analysis. This means that a factor accumulation of these elements is exactly the same as those of each element
