3 Exercises in class: exercises will be graded; final written exam (about 1 hr long) content of the exercises.

4 Field studies: three-day field trip to Dalarna, cost ?00 kr. 20 points.

5 ”Case study”: A written summary and oral presentation focus on the geological aspects in association with engineering projects INTERESTING and SOMETHING NEW

6 ”Case study”: both in English The oral presentations longer than 10 minuets the written summary is not to be longer than one A4 page

7 ”Case study”: graded on content, relevance, and quality

8 The final grade TEN1 = written final test & home test ÖVN1 = labs and exercises and test of the lab exercises Final Grade=  [2(TEN1) + 3(ÖVN1)]/5 60% REQUIRED FOR PASSING FOR BOTH PARTS

10 Questions?

11 Introduction Geology – is it necessary in Engineering?

12 Rock Properties – what are they? physical properties? mechanical properties? hydrological properties?

13 Physical properties parts of the rocks and soils type of rock –igneous –metamorphic –sedimentary composition –chemical – especially types of minerals –magnetic –electric –radioactivity size of particles composition of particles rock texture – how the particles are arranged and held together cementation, type and degree geological structures discontinuities

15 Mechanical properties response of materials to applied loads rock strength –compressive strength, –tensile strength, –shear strength abrasiveness, or resistance to wear impact sensitivity

19 Hydrological properties aquiclude –a geological substance that does not allow the movement of liquid or gas - impermeable aquifer –a geological substance that allows the movement of liquid of gas easily – highly permeable two end members of a continuous scale impermeable / impervious low permeability moderate permeability good permeability

20 Permeability in a porous rock

21 Permeability in a fractured rock
