Geology (from the Greek Ge, the earth;logos, logical speech or science) is the science of the earth, its constitution, structure and development, of the processes going on in its atmospheric, aqueous and stone envelopes. The earth, the globe is comprised of several shells.
The science of geology is concerned with the earth and the rocks of which it is composed, the processes by which they were formed during geological time, and the modelling of the earth’s surface in the past and at the present day. The earth is not a static body, but is constantly subject to changes both at its surface and at deeper levels.

Pulau Kalimantan yang terkenal sebagai “Pulau seribu Sungai” menyajikan keragaman geologi yang unik. Pada pulau terbesar ketiga di dunia ini kegiatan tumbukan (subduksi) terakhir diduga terjadi pada kala Oligo Miosen, jutaan tahun yang lalu. Dengan demikian proses magmatic tersebut telah menghasilkan larutan hidrotermal yang kaya akan mineral logam terutama emas.

Application of earth sciences to the solution of civil engineering problems or geotechnics constitutes the subject of this book. The point of view is that of the engineer and the earth science particulary geology have been brought into the engineering pattern only when they have direct bearing upon the problems under discussion.
Geology, the science of the earth, is comparativly young but despite its youth it already has done much to stimulaste the stinking the thinking of mankind. Man always has been interested in the earth on which he lives and he long has speculated about places and region beyond the horizon.
To geologist, the field is where rocks or soils can be observed in place, and field geology consist of the methods used to examines and interpret structures and materials at the outcrop. Field studies are primary means of obtaining geologic knowledge. Some studies may be as simple as visiting a single outcrop or quarry, making notes and sketches on the relations between certain rocks, and colle…
