The Relationship between Heavy Metal Contents of Soils and Rice in Coastal Areas, Fujian Province, including Influencing Factors

Yankuang ceshi, 2016
Lead content of soil in coastal areas of Fujian Province is higher than that of soil in other areas and in the background level of China, and is therefore of significant influence on food safety and the ecological environment. Based on Pb and Cd contents

A synthesis of the National-scale Geochemical Survey in the last 50 years in Brazil

Journal of the Geological Survey of Brazil
At the end of the 19th century, classical geochemistry arrived in Brazil through Henri Gorceix, being primarily used in his studies of mineralogy and petrology. Meanwhile, exploration geochemical arrives later, in the mid-20th century.

Exploration geochemistry workshop

, 1991
Specific criteria used for exploration for new ore may be derived from genetic models. These might include specific lithological assemblages, fractionation trends, alteration assemblages and ore-controlling structures, for example. Three "lithogeochemical" methods of use in exploration include: diagnostic petrogenetic trends, obtained from geographical
