Step D Engineering geological map is prepared by prehminary investigation. The map should contain the information on basement geology, main faults and weak layers, main joint sets, loosen deposit such as debris, talus deposit, loess and tephra. Water spring is also important as shown in Figure 5.

To determine the detail geologic properties of studied quarry, samples were taken from different points in the quarry. As a result of microscopic analysis performed on these samples, studied quarry included five main rock types. These rocks were massive limestone (Kl), crystallize limestone (K2), arkosic sandstone (K3), quartz sandstone (K4) and intrusive diabase (K5). To observe the distribution of these rocks in the quarry, firstly, 1/3000 scales of engineering geology map were prepared. Afterwards, cross sections were made according to this map to display the relation of different rock types (Fig. 2).

In Spain, the first two weeks are devoted to the feasibility project with the preparation of an engineering geological map of an area, the assessment of the geotechnical properties of the rock and soil units distinguished and the predictions of geo-hazards related to the feasibility projects. The first three days are reserved for a geological excursion to introduce the fieldwork area and instructions on field classification of soil and rock masses. Then, students survey and explore their allocated fieldwork area. They record observations relevant to the theme of their... 

The Milton Keynes engineering geological mapping project provided valuable experience and lessons for future similar studies. Importantly, the study enabled EGU to develop the principles on which later engineering geological maps were produced and highlighted the need for good subsurface data.
