DOE ISSUES PROCEOURES MANUAL FOR GEOCHEMICAL SAMPLING OF URANIUM The Grand Junction, Colorado, Office, U.S. Department of Energy (DOE), has issued a report entitled "Procedures Manual for Stream Sediment -Reconnaissance Sampling," as part of the National Urani um Resource Eva1 uation (NURE).
The Wolfson geochemical atlas (Webb et al., ) provided full stream sediment coverage of England and Wales but has now been succeeded by the G-BASE stream sediment survey in terms of sensitivity of measurements and the range of analytes. Thus the new G-BASE data provides us with the best insight into the major and trace element geochemistry.
The commonly practiced collection of stream sediment samples in mineral exploration, including the Canadian British Columbia (BC) government’s Regional Geochemical Surveys (RGS), is the ‘grab’ method of collecting fine fluvial silt by hand which, in the typical.

The aim will be to demonstrate the spatial extent of any stream sediment contamination around the mine site and, 1. GEOLOGICAL MAPPING AND GEOCHEMICAL SAMPLING. The objective of the work program was to search for gold mineralization, by following-up geochemical anomalies from basal till sampling by Geoscience BC (Jackaman and Sacco, ), and geochemical anomalies from stream sediment sampling by the BC Geological Survey.
dards for geochemical mapping (Darnley et al., ). Panned heavy-min-eral concentrates and stream-water samples are often collected at the same time as stream-sediment samples. Collection procedures for these samples are described in other leaflets in the series.

During the Geological Survey of South Africa embarked on a regional geochemical stream sediment sampling programme which will eventually cover then entire million km 2 of the country.
Samples are collected at an average density of 1/km 2 and where possible from first order streams. To date, samples, representing 16% of the area of South Africa, have been collected.

Cruikshank I, D.M. Hoatsonl & J.G. Pykel A geochemical orientation study in the Davenport Province, Northern Territory, indicates that stream-sediment sampling is an effective geochemical technique for mineral assessment, despite.
Stream sediments are widely employed in reconnaissance exploration for gold especially in areas where outcrops are scarce and the overburden thick such as in the eastern Cameroon goldfields. In this study, stream sediment samples were collected from the Lom river drainage basin. The study aims at identifying the main geological processes affecting the geochemical data from the sediments by.
A reconnaissance geochemical stream-sediment sampling survey was conducted in a 1,km 2 ( mi 2) area in the central part of the Okanogan Range, adjacent on the west to a 2,km 2 ( mi 2) area previously studied.
The initial part of the study entails a reconnaissance geochemical stream sediment survey, in which samples of stream sediment weighing approximately g each are collected from depths of cm along river beds over an area of km2.

Wet and dry sediment samples were collected throughout km2 arid to semiarid area and water samples at available streams, springs, and wells.Sampling Design Stream-sediment sample sites were chosen to provide representative coverage for a geochemical assessment of metallic mineral resource potential in the study area.
The study area was divided into one-square-mile cells.
