Role of 'Humus Matter' in The Formation of Geochemical Anomalies
Residual soil is one of most widely employed sampling materials for tracing geochemical anomalies in geochemical exploration. Systematic studies on the phenomenon of the formation of geochemical anomalies in residual soils are being carried out by the Geolo…

Factor Analysis As An AID In The Interpretation Of Regional Geochemical Strea…
Interpretation of regional geochemical survey data requires consideration of the effects of bedrock geochemistry, weathering and other secondary factors tending to modify the bedrock-soil-stream sediment relationship. Visual interpretation of complex multielement data may only serve to recognize the obvious

The Homogeneity Of Six Geochemical Exploration Reference Samples
U.S. Geological Survey analysts have made more than 4fi,OUO determinations on six geochemical exploration reference samples for the purpose of furnishing data on the homogeneity of the samples. The samples are considered to bL• sufficiently uniform to be use f'…

North Sumatra geochemical and mineral exploration project
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 …

Proposed work plan in exploration geochemistry map and report presentation po…
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:

Geochemical practice in the exploration of soil and gas
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…

In the first place, most chemists work with materials whose chemical formulae are fairly simple, and in which the ratio of the numbers of atoms of one kind to the numbers of atoms of another are small integers, or fractions of small integers. Among such compounds are NaCl, Al203 and Si02• By contrast, the geochemist often stud…
