The Geology & Petrography of Timjaghas and its Environs

The study area of Timjaghas lies between Latitude 09°19¿ 00¿ N to 09°20¿ 30¿N and Longitude 09° 9¿ 00¿E to 09° 13¿ 30¿E on the Pankshin sheet 190NW. It is part of the Panyam Volcanic line. Geologically, the study area is characterized by the newer basalt and the biotite granite. The newer basalt is believed to be Tertiary in age. These basaltic rocks have been weathered forming laterites. The biotite granite is also underlain which is part of the Basement Complex was extruded by the volcanoes. Structurally, the study area has features such as veins, fractures and joints with structural trends in the NW-SE direction. Petrographically, the major minerals observed are plagioclase, olivine, amphibole, and quartz and accessory minerals such as zircon, opaque, iron oxide. Economically the rocks are not very important but can be useful in engineering geology in terms of construction materials.
