Geology, the science of the earth is a fascinating branch of study in Natural Science. It is fascinating because it explains to us the development of topographical scenery on the surface of the land such as the high mountains (the Himalayas, the Alps etc.,) vast plains, volcanoes, waterfalls, grand canyons and coral …
Geoscience has a vital role to play in underpinning the social, economic and indus• trial infrastructure of nations, now and as we move into the 21st century. If we are to have the mineral and energy resources to sustain a global population of 10 billion or more; if we are to manage the fragile environment we cohabit, mitigate against the…
The machines are equipped to run at U.K. mains voltage and frequency, ie 240v 50Hz, and consume 146VA power at full load. Computers are sensitive to voltage fluctuations, and '.even more so to sudden voltage failures. It is usually prudent to install some form of protection device between the mains and the computer. Mains-born interference can take …
This report focuses much on regional geochemistry as a system for mapping of the secondary environment. The reasons for this are that geochemistry has during the past decade found applications far beyond the traditional ones in the search for mineral commodities. The fields that applied-- geochemistry currently finds applications to are primarily:

Nonnally oil or gas occupy only a small fraction of the total pore -1. volume in the subsut!l:-ece; the rest of the spJlce contains water_.Sometimes the water associated with the oil is fresh, but usually it is salty. In general, the deeper and older a rock is, the saltier the water it contains. Thr origin of oil-field brines is not well understoo…

As shortages in the supply of mineral cotmnodities become more probable, there is an•increasing need for reliable and comparable reserve/resource data. It is therefore necessary to standardize the traditional classification procedure by quantifying the three basic criteria in resource evaluation: economic feasibility, geologic assurance, re…
