Abstract :
A qualitative interpretation from the regional aeromagnetic
data in a 40Km2 on the south western portion of the Torbate Haidariye sheet and semi detail aeromagnetic and potassium in 150Km2 on the west central portion of the Kashmar sliced has beer made. Regional data shows a broad strong elipsoidal anomaly in (lie south west of Torbate - Haidariye 1: 25000) sheet wich correlates with the mapped granodiorite, granite, andesite and part of the tuffacous material close to the Koohezar area. This anomaly extends in east west direction to the Kashmar sheet. Magnetic character of this regional data limits the resolution of the magnetic characteristics of the various intrusives and volcanic which are favorable lithologies for the formation o gold and has metal deposits. Interpretation of the regional and semi detail data does not show any intrusive signature arround the Dehane Siyah and surrounding. Companative studies of the regional magnetic data with mapped geology and copper distribution (1: 1 000000) indicates paralehism of copper to similar high curvi linear magnetic anomalies between Abbassabad Sabzevar and Dehane Siyah area. The simlarity of copper distribution parallel to magnetic anomalies. Lithologies and age between Abbassabad and Denne Siyah makes the former is a model for the latter.
Comparative studies between geology, semi detail magnetic and potassium data. satelite alteration image, old mine, and stream geochemical data (1: 100000) shows Dchane-Siyah area has the highest potential in copper mineralization relative to the investigated area of the surrounding (Zangaloo. cheshmine. and cheshme-gaz). Pegging the Dehane-Siyah aeromagnetic anomaly to the ground. measuring the magnetic susceptibility of the lithologies involving the magnetic anomaly, ground magnetic profile measurement through it, and laboratory related ferromagnetic studies are essential for the understanding of the relation of magnetic anomaly with ore deposit and host rock.
