ABSTRACT: The study area is located
in the west of Iran and in the north of Asadabad. This is the range between
Eastern lengths of 00', 48° to 15', 48°, and northern latitudes of 45', 34° to
00', 35°. This range is limited from north to the asphalt road of Hamadan
Qorveh, Sanandaj, and from the East and Southeast, to Asadabad of
Kermanshah-Hamedan road, and from the West to Chahardoli plain and from the
south to the plains and the town of Asadabad. According to the geological map
of the study area, intrusive outcropping of diorite-gabbro of Almoqlaq, and
quartz syenite is at Almoqlaq mountains. Intrusive rocks of the region, based
on the total Alkali oxide, against silica rocks of study area fall within the
quartz monzonite, gabbro, granodiorite, granite, and syenite between quartz and
alkali granite. And granite in the study area (due to aluminum saturation
index), is in the range of metaluminous, and metaluminous to peraluminous.
Based on normalized spider diagram with the upper crust, the typical study area
belongs to this model, and most of the elements are placed near or on standard
line of 1.
