Morphometric age of Khatoon-Bagh cinder cone, NE of Mahabad, West Azerbaijan province

Scoria cone near Khatoon-Bagh, NE of Mahabad in West Azerbaijan province consists of 3 Parts: Lower part containlayer of scoria, ash and tephra, middle part consist of volcanic bomb-bearing scoria and finally (Cupper part) a layer full of bomb. Their composition is mainly olivine basalt. The morphometric data used for morphologic age were either derived by manual measurement on topographic maps and by Digital Elevation Model-based (DEM) calculations. The main parameters of cone such as height, basal and crater diameter have been measured for calculation of Hco/Wco ratio and average slope angle. The main parameters show that the basal shape of this cinder cone is elliptical and at the crater is super elliptical, therefore can categorize it as horseshoe-shaped cone. The comparison of main parameters from a number of previous studied cinder cones from around the world suggest that dimensions of Khatoon-Bagh cone is similar to global average. Since with the increase in age and degradation of cone, the height, height to diameter and slope angle of cone will decrease, so Hco/Wco could be used for morphometric ages. According to Wood (1980b) and Sucipta et al. (2006) aging data and Porker (1972)’s relations, the relative age of Khatoon-Bagh cinder cone estimate 0.7-2 Ma which is in agreement with stratigraphic age in geological maps.
