3 GEOLOGICAL MAPS AND BASE MAPSTo make a geological map you need a topographic base map on which to plot your geological observations in the field. You will also need a second map on which to replot your interpretation of the geology as a fair copy map to submit to your employer or supervisor, when your work is complete.3.1 Types of Geological MapGeological maps fall into four main groups. These are: reconnaissance maps;maps made of regional geology; large-scale maps of limited areas; and maps made for special purposes.3.1.1 Geological reconnaissance mapsReconnaissance maps are made to find out as much as possible about thecgeology of an area as quickly as possible. They are usually made at a scalecc of 1:250 000 or smaller, sometimes very much smaller. 3.1.2 Regional geological mapsReconnaissance may have given the outline of rock distribution and general structure; now the geology must be studied in more detail, most commonly at a scale of 1:50 000 or 1:25 000, although any resulting map will probably be published at 1:100 000.Regional geological mapping done on the ground may be supported by systematic photogeology, and it should be emphasised that photogeological evidence is not inferior to information obtained on the ground although it may differ in character. All geological mapping should incorporate any techniques which can help in plotting the geology and which the budget will allow, including geophysics, pitting, augering, drilling and even t
