PURPOSE: A division marking device for a geological survey is provided to be fixed on the uneven or inclined ground without an inclination while workers check first and second inclinometers. CONSTITUTION: A division marking device(2) for a geological survey comprises a case unit(110), a fixing shaft unit(120), first and second division marking units(140,140'), and a drive pin unit(150). The fixing shaft unit is placed in a first inner space of the case unit, and divides the first inner space. The first and second division marking units are respectively placed at the upper and lower parts of the fixing shaft unit, and placed in the first inner space. The first and second division marking units are unwound out of the case unit, and comprise installation spots which guide first and second marking strings. The drive pin unit comprises a hitting rod, a support plate, and a drive pin. The support plate is formed on one end of the hitting rod to support the bottom of the case unit. The drive pin is extended from the support plate, and inserted into the land.
