It is important to understand the roles of the engineering geologist and the geotechnical engineer when considering, generally, how land is to be used. This is especially the case for Malibu because of its relatively complex geology. Geology commonly is defined as the scientific study of earth history,...

Structural Geology
Heat from the Earth’s interior is released through the processes of volcanic eruptions and motions of the lithospheric plates. As described in the section on plate tectonics, plate motion is accomplished in three...

NOTS ON LAMPROPHYRES
INTRODUCTION
The term lamprophyre was introduced by Gumbel (1874), to
describe a group of dark colored dyke rocks from West Germany. In Greek the word
“lampros” means bright or glistering. The rock collected from West Germany
was bright due to biotitic flakes.
According to IUGS Sub-Commission lamprophyres...

Center of the earth
Center of the earth:
The first thing to remember is that NOBODY has ever been there, so what you are about to hear is barely past the Wild and Crazy Idea stage. What we think we know comes from a study of how earthquake (seismic) waves travel through the earth, and how long it takes for them to get...
GIS in ENGINEERING GEOLOGY
INTRODUCTION:
A full three-dimensional GIS system is obviously the best system to handle engineering geological data and analyses. For regional studies, this may lead to very extensive databases and consequently long calculation times, although this may become unimportant with further development...
Branches of GEOLOGY
INTRODUCTION:
Broadly stratigraphy deals with the succession of geologic events and / or rock layers from the beginning of the crustal formation up to the present time. It aims at establishing and describing the correct order of superposition of rock-units on the earth's surface. Thus, it actually establishes...

Role of engineering geology in engineering
INTRODUCTION:
The overall success of the river linking is based on the engineering safety of the dams. Channels and structures in the link. As geological conditions that would lead to failure of tunnels, dams. Aqueducts and erosion of channels are of common occurrence a geological study of the...
Geological materiyal
INTRODUCTION:
Engineers work with large volumes of soil and rock which will contain variable amounts of fluid in their pores and fractures. It is helpful to distinguish the material from which these volumes are made from the mass which they form. Sediments are made from particles, big and small, and...
